The report contains detailed maps and site descriptions for all sites that have been sampled during the first seven years of the program. Locations (Nominal Site Centers) provided are the most recent available for a specific site and are based on chart data and Global Positioning System (GPS) positions, when available. GPS positions have been obtained for approximately 75% of the sites sampled. Loran C positions are not available for the Caribbean, therefore only GPS positions are provided. GPS and Loran C data are provided in Appendix A. SamplingHistory In 1986, GERG undertook the first NS&T Mussel Watch site sampling in the Gulf of Mexico. GERG's efficiency in field sampling is attested to by the fact that during the course of the past eight years of the project, the Gulf Coast field collection effort increased from an initial.50 sites in Year I to 86 sites by Year VII. The days in the field which were required to complete the sampling decreased from. 48 days in Year I to 26 days in Year IV, despite the 40% .increase in sampling effort. Years II.and III sampling showed similar efficiencies, requiring 31 and 30 days respectively. The sampling dates established in Year V dictate a time frame during which all subsequent sampling will be completed: Texas and western Louisiana sampling is done in December, and sites in eastern Louisiana, Alabama, Mississippi, and Florida are sampled in January. In Year VII we added Puerto Rico, which is sampled in February. No new sites were added in Year VIII. The sites from which we have collected oysters in the Gulf of Mexico have not been limited to the coastal embayments but have included a number of sites which face the open Gulf and can only be reached by long boat transits. Stretching from Port Isabel in the lower Laguna Madre of Texas to Bahia Honda Key in Florida, the study area encompasses over 1500 straight line coastal miles. The actual distance to be traversed is appreciably longer since access to many remote areas within the embayments is by circuitous route. A single field crew sampling half of the Gulf sites would travel over 8000 miles I during a field season. This limited access to the shoreline combined with the very shallow waters of most of the bays (63% of all maintenance dredging in the continental U.S. is done in the Gulf of Mexico) has supported our original contention that the Gulf of Mexico sites are the most difficult U.S. coastal sites to sample. Bivalve Distributional Patterns in the Gulf of Mexico Distributional patterns of molluscan assemblages are dependent on water depth, substrate type, turbidity, salinity, and wave energy. Parker (1960) defined molluscan assemblages along the Gulf coast based on salinity and substrate type. The important inshore, estuarine, and lagunal assemblages are as follows: I . River Influenced, Low-SaLinity Assemblage - The largest and most abundant bivalves in this assemblage are: Rangia cuneata - Common in beds all along the Gulf coast, large; Rangia flexuosa - Less abundant than R. cuneata; Polymesoda carolinensis - Missing from Mobile, Alabama, east and Matagorda Bay, west and south and Macoma mitchelli - common in most low salinity lagoons and estuaries; small. This assemblage is. characteristic of soft-bottom areas surrounding river mouths, where the salinity is usually less than 1OToo. Typically, the numerically dominant mollusk in this zone is Rangia cuneata. Rangia cuneata, flexuosa, and Polymesado carolinensis have life spans of several years whereas Macoma mitchelli is an annual species. Of the longer-lived species, Rangia cuneata is also the biomass dominant in this assemblage. II. Delta - Front Distributary and Interdisciplinary Assemblage .- The largest and.most dominant bivalves in these assemblages are: Rangia cuneata - not as abundant as in river influence assemblage; Rangia flexuosa - more abundant in interdistributary bays; 2 Macoma mitchelli - rare; Crassostrea virginica - very abundant in higher salinity interdistributary bays; and Petricolar pholadiformis - common, but small. III. Low Salinity Oyster Assemblage - The largest and most dominant bivalves in this assemblage are: Crassostrea virginica - predominates in this zone; and Brachidontes recurvus - at times very abundant. Oyster reefs are abundant where salinities range from 10-3090'0. Most oyster reefs are found in relatively shallow waters. Typically, large reefal structures are formed at right angles to the dominant current flow. These reefs are easily located and are a major geologic feature in most of the bays along the Gulf Coast that were included in this study. Crassostrea virginica is the biomass dominant as well as the most numerically-abundant large bivalve in the assemblage. The mytilid Brachidontes recurvus is usually found associated with oyster reefs. However, it is not as abundant nor as large, and it has no previous baseline established in the Mussel Watch programs. Furthermore, it rarely occurs in other assemblages where C. virginica is an important component. IV. High Salinity Oyster Assemblage - The largest and most abundant bivalves in this assemblage are: Anomia simplex - common, but small; Brachidontes exustus - common, attached to oyster valves; small; Diplothyra smithii - rare; and Ostrea equestris - abundant, long lived species. High salinity reefs form near inlets where relatively high salinity water (34-36%) is constantly renewed by tides. The substrate is old shell. Ostrea equestris is generally abundant and replaces C. virginica when salinities rise above 300loo. Over the long-term, drought cycles frequently result in the replacement of C. virginica with 0. equestris (and vice versa in wet years) 3 along most of the Gulf coast (Parker, 1960). Thus, this assemblage is .effectively identical to the Low Salinity Oyster Assemblage except where salinity causes the replacement of species with other closely related species. In this assemblage, 0. equestris typically is the biomass dominant. V. Hypersaline Lagoon Assemblage - The largest and most abundant bivalves in this assemblage are: Mulinia lateralis - abundant but small; Tellina tampaensis - moderately abundant; and Anomalocardia auberiana - very abundant Hypersaline lagoons and estuaries are common along the lower Texas coast and have salinities ranging from 40-80,Yoo. The species in this assemblage are very abundant but are short-lived and small. The numerical dominant in this zone is Anomalocardia auberiana. In the previous EPA Mussel Watch Program, .genera from the family Mytilidae (the mussels) were used as the organisms of choice.for portions of the geographic range of the mussel watch program. Along the Gulf coast, however, mussels that do occur (i.e., the genera Brachidontes, Lioberus'_ Lithophaga, Modiolus, Geukensia, and others) are often too small and frequently not abundant or widespread enough to be considered as target organisms. Previous baseline organisms along the. Gulf Coast for the EPA Mussel Watch Program were all species in the family Ostreidae (viz. Crassostrea virginica and Ostrea equestris). These two species are frequently biomass dominants, abundant and easily resampled from their respective habitats. The American oyster, C. virginica, occurs in intertidal and sub-tidal habitats all along the Gulf coast (Scott and Lawrence, 1982). C. virginica is sufficiently widespread so that it has been able to be collected at the majority of the designated sites. C. virginica typically inhabits coastal and lagunal environments with salinity levels normally varying between 20-30,7oo, although populations at both lower and high salinities are known. Moreover, as shown above, it is one single species common to nearly all the Gulf Coast and is usually biomass dominant where it occurs. The oyster reefs produced by C. 4 virginica, which make up the bulk of the sites selected for this portion of the NOAA Mussel Watch Program, are permanent and for the most part large features which are easily located for sampling and resampling. In addition, living oysters usually are abundant on these features and are recruited yearly to the reefs; thus, these areas will be able to sustain repeated sampling over a ten year plus period with minimum impact on the population structure of the reef. Clearly, due to the previous baseline established for this species, its abundance, large size, and ubiquitous occurrence along the Gulf coast, C. virginica is the target organism of choice. Although C. virginica has a particularly wide salinity tolerance, a few areas that have been.designated as sites are outside its range. In areas of low salinity which do not support C. virginica, Rangia cuneata is the dominant bivalve. R. cuneata is relatively large and abundant. It is the characteristic organism of the low salinity assemblage and it occurs in most low salinity habitats along the Gulf Coast. R. cuneata is usually found in abundance at the sediment-water interface on soft bottoms. We have attempted to find C. virginica in the high salinity bays in the lower Laguna Madre between Corpus Christi and Port Isabel with limited success. 0. equestris, an ecological equivalent, usually replaces C. virginica in these areas. 0. equestris is usually associated with hard bottoms or mangrove roots and is abundant and large. It has an established baseline for comparison because it previously was used in the EPA Mussel Watch program. In addition, it belongs to the same mollusk family (Oestreidae) as C. virginica. In most habitats which usually do not support C. virginica, 0. equestris can be collected and is the organism of choice. In hypersaline lagoons (i.e., Baffin' Bay, Texas) where C. virginica and 0. equestris are absent, Anomalocarida auberiana could be sampled. This species is small, yet it is very abundant, reaching population levels of -2000 per M2 in some instances. Because of the concerns about species effects, none of the alternate species at the sites which do not support C. virginica have been collected to date. 5 Fieldl.,o&fics Collection and field processing of oyster and sediment samples was conducted by GERG utilizing small boats and a portable self-contained laboratory (used in Years I - VI) which was specifically equipped for sample processing and storage. A field collection crew consisted of two people (sometimes three, depending on the site) using a trailered outboard boat. Table 1 summarizes collection methods and site accessibility. In Years VII and VIII, the processing was not conducted in the mobile lab. Samples were collected, packed on blue ice, and shipped back to our labs in College Station by Federal Express for processing the next morning. Samples from Puerto Rico were shipped via American Airlines as perishable items and were received at the GERG laboratory in less than 48 hours. The Gulf of Mexico field collections were made in four sampling legs. The first leg departed College Station, sampling the -12 sites within a 200 mile radius of College Station (Brazos River, Galveston Bay, and as far east as western Louisiana) in a 5-day period. Samples were returned to College Station by Federal Express, private aircraft, and/or the returning field crews. The next sampling leg was based at Port Lavaca. During this five day period, two boat crews completed sampling the -19 remaining Texas sites and returned to College Station. Following the Christmas holidays, sampling resumed with two boat crews who sampled from central Louisiana, through Mississippi, to Alabama. Upon completion of the - 20 sites as far east as Mobile, Alabama, the sample crews returned to College .Station. The last leg sampled 24 sites in Florida. After completion of the Gulf sampling, the boat crews returned to College Station. In Year VII a fifth sampling leg was added in February to sample Puerto Rico, where local fishermen were employed to use their boats to take us to collection sites. 6 Table 1.

In the Caribbean, logistical concerns were much more complex since all collection gear had to be carried aboard airplanes and permitting and regional politics played a much larger role. In the Gulf of Mexico, one major problem concerned accessibility to the oyster sites. Some samples were little trouble to obtain, such as from rock rubble beneath a highway bridge in Galveston, but some were difficult, such as ones that required a 35 mile drive from the nearest motel to the launch, a 15 mile boat ride through Louisiana marshes, and 10, miles alongshore in the open Gulf to a site that had to be sampled by dredging. Not only was this situation difficult, but the site was situated within a private lease which extended to all oyster bottoms in the bay system. It was owned by a family who initially met us at the boat launch and who were adamantly against our sampling from their lease. The site was located on what may be the most prolific oyster beds in Louisiana (and, therefore, on the entire Gulf coast), and was exposed to outflow from the entire Atchafalaya drainage basin. Particularly in the Gulf, we had need of. a relatively large, fast and seaworthy boat that had a draft shallow enough to traverse the shallows en route to the site and to get on the reef for sampling. Proper equipment and navigational gear was needed to safely cross the Mississippi Delta area, where landforms and bayous in and around the delta showed essentially no conformity to the most recent NOAA navigatio)jJ,'9'.,1 charts, as was verified by our direct experience in the field and from very recent aerial photographs. The other sampling extremes were typified by sites such as Cockroach Bay, which was accessible only with a very shallow draft boat and which required a two mile ride through an uncharted mangrove swamp and across oyster bars, over which the boat had to be dragged even on a flood tide. On the other hand, sites such as Dry Bar in Apalachicola (where dredges were absolutely forbidden) required about a 7 mile run across the open bay in the Boston whaler to a site so shallow that it was collected by hand while wading. 10 The distance between the Gulf sites measured 1500 nautical miles when the straight line distances between nearest sites were totalled. However, a single boat crew completing half the sites over the range from Laguna Madre to Naples drove over 8000 miles in a sampling season because of the limited and circuitous routes to launching ramps and sites. In the Caribbean, transportation on land and on the water had to be arranged on each island and at each collection site. There were few commercial or recreational boat rental sources; therefore, local fishermen had to be -located at each collection site for which boats were needed. Local fishermen were -sometimes hesitant to take scientists to their oyster harvesting areas since they believed that there could be some interference with their livelihood. Permits Collection of oysters in all the affected states was regulated by state agencies. A scientific collecting permit was required prior to collection in Texas, Louisiana, Alabama, Florida and the Virgin Islands. Prior written permission was required in Mississippi. Collections in Puerto Rico were made under the University of Puerto Rico permit. Additionally, the preponderance of privately leased oyster beds in Louisiana required that we obtain permission from the individual lease holders for those -instances where the site was (or was thought to be) located in a leased area. Permit applications were submitted to and obtained from the following: Texas - Mr. George C.

Box 5000 RUM-LTPR Mayaguez, Puerto Rico 00681-5000 Sampling Gear Boats Two boats were used during the course of collection. A 17' Boston Whaler with an 88 hp engine and electric tilt/trim and a 16' Whaler with an 88 hp engine provided the greatest versatility and utility in sampling. Each boat was equipped with dual fuel tanks, a VHF radio, Raytheon Loran C, a fathometer, and emergency/safety equipment. A handheld GPS receiver was used on one of the boats during Year VII. The boats were trailered to a launch site near the sampling site. Due to the remote location of several sites, running times of up to 3 hours were required to get from the launch site to sampling sites. 12 Radio Communications All vessels were equipped with CB/VHF marine radios. This allowed us to coordinate sampling activities between both boats when they worked simultaneously and kept us in contact with the Coast Guard and other vessels operating in the area if emergencies or difficulties arose. It also kept us abreast of coastal weather conditions which were broadcasted continuously on the VHF weather frequencies. Safety Considerations All boats were equipped with Coast Guard-required safety and emergency equipment (life jackets, lights, reserve fuel, first aid kit, etc.). Our group conducts extensive field activities, approximately 120 man months on oceanographic cruises per year, including over 40 weeks on chartered boats that we fully equip and rig out; thus, we were well aware of applicable safety considerations and the consequences of failure to prepare for these contingencies on a field such as the NS&T program. Sample Collection Oyster Collections Oysters were collected by hand, with tongs, or by using a dredge (Table 1). Collection by hand was the method of choice and was used at intertidal and shallow subtidal sites. Loose oysters were simply picked from the reef and were separated from attached shell debris or other oysters by using an oyster knife or chipping hammer. . In some areas where the use of a dredge was prohibited (e.g. Apalachicola Bay), subtidal sites we re sampled using oyster tongs. The oysters were separated from one another by using oyster knives or chipping hammers. At the deeper subtidal sites and where oysters were obtained directly from commercial oyster fishermen at their privately leased sites, the oysters were collected with steel or stainless steel oyster dredges. Clumps of oysters and shell were separated to individual oysters as before. 13 Sediment Collections Where water depth permitted, sediments were sampled by hand using a Teflon-coated scoop. Prior to each use the scoop was cleaned and rinsed with acetone and then methylene chloride to remove any trace of residual organics. Spent solvent was collected and returned to GERG for proper disposal. The upper 1 cm of sediment was removed by the scoop and was placed into the appropriate container. In water depths where direct sampling was not possible, a stainless steel box corer mounted on a long pole or on a rope with a messenger was used to bring a sample of the substrate on board the boat and the Teflon-coated scoop was used to remove the top 1 cm subsamples for analysis. Field PhwesAv Salinity and Temperature At every site, the temperature of the surface water was recorded. Salinity was measured either at the site with a temperature compensating refractometer or a sample was collected and returned to the mobile field laboratory where salinities from a number of sites were measured at constant temperature with a calibrated refractometer. Oyster Processing Oysters were processed in GERG's samp le processing laboratory. Rapid processing of oysters was required because of the coincident collection of histopathological data after collection and prior to freezing'. In addition, the hi stop athological procedure required follow-up handling and immediate cultures which could be achieved only under laboratory conditions. We used this opportunity not only to provide the histopathological data but to provide additional data on relevant bivalve parameters. This process allowed the field collections to proceed efficiently while separating the collection activities from the processing functions. As samples were collected on the boat, they were segregated and labeled according to station and replicated. Efforts were made to retain organisms in 14 the same size range for sampling so that organisms pooled for analysis at a site and the replicates were of similar age, or maturity. Samples were stored in ice chests aboard the boat until the day's sampling was complete. At that time they were transferred to Freez-Safe insulated containers which were packed with frozen blue ice for shipping. The samples were driven to the nearest Federal Express office for next-day delivery to GERG. The processing protocols for oysters are shown in Figure 1. Cleaning and Shucking - Oysters were scrubbed free of mud and debris whileat the collection site. Pure bristle brushes and water from the collecting site were used for cleaning. Oysters destined for organic and histopathological analyses were -measured for length and displacement volume and were opened and processed in the GERG laboratory. Dissecting and Gonadal Preservation - Twenty oysters from each of three sampling stations at every site were processed for histopathological and gonadal development study. After the initial displacement volume of the washed oysters was determined, they were arranged on a stainless steel tray. Each, oyster was measured (axial length) and was opened with a solvent- washed stainless steel oyster knife. A complete cross section of gonadal tissue was excised from each oyster and was placed into an individual tube of Bouins solution. A small snip of mantle tissue was also removed and was placed into individual tubes of fluid thiglycolate medium (FTM) for the* determination of the incidence of the oyster parasite Perkinsus marinums. Trace Organic Processing - The remaining oyster tissue was excised from the shell and was placed into a pint mason jar which had been combusted in a muffle furnace to completely remove trace organics. The tare and gross weight of the jar -and contents (20 oysters) were recorded on the lab form with the individual lengths of the oysters. A Teflon liner was placed under the jar seal, and the labeled sample jar (one for each of three stations in a site) were frozen in laboratory deep freezers. Trace Metal Processing - A separate 20 oysters from each of three stations within a site were washed as above and were set aside in plastic trays for metal analyses. The oysters were collectively measured for the initial displacement volume. Because of their sharp edges and the need to ensure that they remained closed prior to processing, the oysters had to be individually wrapped in singlefold paper towel and bound with rubber bands before they were double bagged in plastic trash bags, labeled and stored in the freezers. 15 .affimph Oyster Sites Measure First Displacement Volume (VI) OpenISheiF] Measure Tnteraxial Length Snip Mantle Section Cut.Off Bottom Half Culture tube for 5 MM Cross Perhinsus Section: I Snip/ ube First 10 Oysters 20 tubes 'Cut Bottom Bouin!s Adductor Solution Remaining Label Tub In Vial Tissue Measure & Cap I I Second Label & Jar For Organics Displacement Store 20 Oysters Volume (V2) Store Ambient I Ambient F bel Outside I Teflon Liner Retain Shells j!@FZE= from I station per site Discard othe Shells Return to GHMG Figure 1. Sample processing protocol, oyster sites 16 All opening and further processing of oysters (measurement of shell length and second displacement volume) was done at the analytical laboratories under clean room conditions. National Biomonitoring Specimen Bank (NBSB) - Bivalves from five sites on each coast were sent to the NBSB. The NBSB archives were housed at the National Institute of Standards and Technology (NIST, formerly National Bureau of Standards). Processing of these samples was conducted in the GERG facilities. The processing protocol is depicted in Figure 2. A and B replicates were comprised of 10 bivalves each from the three stations at a site (30 individual specimens in A and B). The composite sample of 10 oysters from each station was scrubbed clean of mud and debris by using the pure bristle brush. The bivalves were placed into a teflon bag and care was taken to keep the inside of the bag at the point of sealing dry. Air was evacuated from the bag as much as was practical, and the bag opening was sealed with the heat sealer. Air-tightness of the first seal was checked by depressing the bag and listening for -escaping air. The bag was resealed as necessary and a second seal was then made about 1/2" out from the first. The sealed bag was then placed into another teflon bag with the sample label between the two bags. The sealing process was repeated on the outer bag, and the resultant double-bagged sample was placed on dry ice for shipment to NBSB. A data form provided by N_BSB was completed for each site and sent along with the samples. Shell Preservation - Oyster shells that were processed and opened in the laboratory (the sets of 20 for histo, gonadal, and organic analyses) were retained and archived for possible future study. This set from each site already had the most complete data set (length, wet weight, mantle cavity volume, as well as contaminant, histo, and gonadal index) and would be of greater value than a set taken separately or for only one parameter. The shell pairs were placed into cloth bags (soil sample bags), labeled, and stored in 5 gallon plastic buckets with ethanol as a preservative. Sediment Processing Sediment processing was essentially completed at the site, whether on the boat or on the shore in the case of shore-accessed sites.

Trace Organics and Trace Metals - The separate samples for organics and trace metals, contained in a pre-combusted half pint glass jar and a heavy duty pint zip-lock bag, respectively, were labeled and assigned a unique identifier code. They were shipped to GERG and stored in the freezers until analyzed. Grain Size - Sediments collected for grain size analysis were stored in zip-lo6k or whirl-pack bags at ambient (above freezing) temperatures. As with the previous samples they were labeled with collection and site information and given a discrete identifier code. Sediment Ancillary Measurement - Sediment ancillary measurements were run on aliquots of the samples taken for organic analyses; thus, no additional sampling or processing was required in the field. National Biomonitoring -Specimen Bank - At five sites per coast, sediments from all three sites were composited into two replicates (A and B) for NBSB archival. The procedure is illustrated in Figure 3. Subsamples from all three stations at a site were combined into a composited sample. The subsamples were placed in teflon jars. The jars were filled only to within 1/2" to 1/4" of the top to allow for expansion during freezing. The label was taped to the outside of the jar, and the sediment samples were stored on dry ice for air shipment to NBSB. The NBSB data form was completed and sent with the samples. Sample Handling and Chain-of-Custody Sample collection was under the supervision of the field party chief who recorded the data and checked off the samples that were acquired against a prepared station list. Samples and copies of the data sheets were shipped to the laboratory manager at GERG. The lab manager supervised the processing of samples in the lab, the labelling, and the storing. The manager also prepared an inventory list of samples that were collected and were to be transferred. All samples and records were transferred to the Quality Control Manager who checked the samples against the prepared station list and stored the samples for subsequent disbursement to the different analytical groups and final storage. 19 Sediment Sites 3 Box Gores Per Station Specimen Bank Sample 10 Sites Only Remove Upper I cm rganics 3 Scoops per Trace I metals 0 Gr Size Center Scoop Inner Scoop 'Outside Scoop Box Core 20 35 gm 70 gm 70 gm Cm Each From 3 Stations I Subsample I subsample I Subsample Per Site From Each From Each From Each CompositeA Composite B Box Core Box Core Box Core Teflon Bag Teflon Bag I Ziplock Bag I Jar Per I Ziplock Ba I I Per Station Station Per Station 9 Label Label 100 gm Total 200 gm Double Bag Double Bag Label Outsi Label Outsidel Label Outsid Double Bag Teflon Lid Double Bagi Liner Store On Dry fee AMBIENT S i on Dry Return to lee to NTBS G19IRG r R @AMWW, Figure 3.

Field Sampling Criteria 'Definition of Stations and Sites A site, the smallest geographic unit sampled, was selected to be representative of a target area, general location, or bay system. Once selected, the site was sampled at the same location each year. Within each site, three independent stations were sampled in order to characterize the site. Offshore subtidal sites were -400 m radius circles. Latitude and longitude of the site was measured at the center of the circle. Shoreline intertidal sites were defined as 100 m linear areas along the tidal horizon to either side of the site center. Sediment sites were generally coincident with the bivalve sites. However, when subtidal bivalve sites did not meet the sampling criteria, separate sediment sites were selected. If at all possible, these sites were located within 2 km of and exposed to the same water mass as the bivalve site. The sequence of events in selection of new sites is shown in Figure 4. Eighty-three (83) sites were established in the Gulf of Mexico and three (3) sites in the Caribbean during the first seven (7) years of the NS&T program. For the first six years of the study three stations at each site were sampled and each station was characterized by three replicate composited samples taken for sediment analysis and a composite bivalve sample made up of 20 oysters. Selection of the three sampling stations was based on the historical locations as described for each individual site in this report. In Year VII the number of oysters collected at each of the previously sampled stations was reduced to 20 to 22. The composite bivalve sample was made up of 7 to 8 oysters from each of the three stations. 2L Bivf dve Site Selection CAterla Bivalve sites were initially established according to the following criteria: 0 The site shall have indigenous oysters of a suitable size (7-10 cm for C. virginica or C. rhizophore) which are available for collection annually. 0 The site shall integrate contaminant accumulation from nearby or surrounding areas and shall be outside the zone of initial dilution of a "dumpsite or point-source discharge. The site should have sufficient bivalves, such that repeated annua harvesting- of 250-400 bivalves will not seriously deplete the resource. � The site should be suitable for follow-up sampling (e.g., not anticipated to be be physically disrupted by development activities or dredging). � Sampling substrates will be limited to rock (including lip-rap), and or mud (or mangrove roots in the case of C. rhizophorae). Artificial structure such as pilings, and navigation aids will be avoided if possible in order to avoid potential contamination. � Provided other criteria are met and where feasible, the bivalve sites should coincide with historical monitoring sites (e.g., USEPA Mussel Watch monitoring sites). Each year the field sampling effort has reoccupied as many of the historical sites as possible. It has become necessary to relocate or abandon a few of the established oyster sites over the years due to one or more of the following circumstances: � Bivalve populations were no longer present. � A construction project or dredging activity precluded sampling. � Collection of bivalves was logistically impossible or would endanger the field personnel. � Permission to sample a site or gain access to a site was denied by a landowner or a leaseholder. When another location was chosen for sampling, a determination was made by the COTR as to whether the new location was considered a minor it relocation" of the'site or whether the new site was significantly different and should have been considered a newly established site.

Sites minimally relocated could retain the same name or could be renamed if the new name better signified the relocated site. Sediment Site Selection Criteiia In most cases sediment sampling coincides closely to the bivalve stations. Because of the affinity of the target species for and the ubiquitous distribution of depositional zones in Gulf of Mexico estuaries, coincident sediment and bivalve sampling was generally not difficult. The specific criteria for sediment sites were: � The site shall be subtidal (never exposed at lowest tides), � The site shall be exposed to the same water mass as the corresponding bivalve site, � The site should be located as near as possible to and preferably not more than 2 km from the bivalve site, � The site shall integrate contaminants from multiple- sources in the surrounding area'but shall not reflect inputs from an individual point source of contamination. � Previously sampled or historical Mussel Watch locations (e.g., EPA sites) should be included/reoccupied where possible. Field personnel were responsible for determining the suitability of the sediment sample. Only sites which were mmally (40 percent) fine sediment (silt and clay) were sampled for sediments. Samples that did not meet this grain-size criteria were not-'6nalyzed for the trace elements and trace organics. Therefore, grain size determinations were made prior to the chemical analysis. 24 SamplingSummary Sampling Problems It has been our intent to sample the locations prescribed by NOAA during Years I through VII of the program. However, in the field we have found that at a few sites, many factors worked against this both in the initial first year sampling and then again in the subsequent years when we returned to resample the same sites or new sites. Some of the prescribed locations could not be used because when we examined them in the field, they did not meet the most basic site selection criteria. For example, Bill Days Reef in Espiritu Santo Bay was a dead reef in Year I and II and an alternate site at another location was substituted. A similar substitution was, made for the Hillsborough Bay site in Tampa Bay. South Point at East Cote Blanche was completely devoid of living oysters. Since there was,no alternate location which supported oysters in the East Cote Blanche area, this site had to be deleted and no alternate was substituted. Minor shifts in sampling sites have been required between sampling years to accommodate yearly fluctuations in the abundance and availability of oyster populations at chosen sites. When these minor changes were required, we attempted to maintain the sampling stations as near the original location as possible. We expect this.practice to continue over the course of the study as we anticipate recurring problems such as dredge material burying the entire reef (CCIC), our inability to relocate our sampling stations on submerged reefs in the absence of navigational references or aids in close proximityj the near total depletion of public oyster beds by harvesting, disease, and predators (MBLR), and the depletion of available oysters attributable to sampling for this study (SAW-B and TBHB). Thus, in some instances, it has not been possible to return to the precise site locations sampled in the previous year. Ensuring continued sampling at the. same stations for all sites will require the relocation of some of the prescribed sites perhaps some distance from the original selected location. The sediment sites were to coincide with oyster sampling sites, inasmuch as fine grained depositional sediments may be co-located with the oyster reefs. The primary determining factor in sediment sampling was that the sediment contain less than 80% sand or coarser fraction. While we have 25 been unable to devise a method which would confirm this compliance in the field, every effort was made to obtain sediments of as fine a texture as we could subjectively determine. In most cases, this was not a problem, as sediments adjacent to the reef were indeed of fine texture. However, in some cases, it was difficult (e.g., Bird Island in Charlotte Harbor, Mullet Key Bayou in Tampa Bay or the Naples Bay site). These sites, as well as others, were characterized by broad expanses of sand and carbonate sediments. Fine grained silts and muds were either completely absent or confined to dredged canals used for recreational boating quite distant from the oyster collection site. Thus, sediments from some areas will not meet the requirement for being more than 20% silt and clay, or they will be so far removed from the oyster site that they .will not represent the integrated, contaminant accumulations to which the oysters have been exposed. Comprehensive sediment sampling was undertaken in Years I, II and III of the study. However, no sediments were analyzed in Year III. In Year IV sediment samples from new Years III and IV sites were analyzed. In Year V, only 13 sediment sites were sampled.' In Year VI, two new sites were sampled for sediment. Sediment collections in Year VII was confined to five newly established sites and PBPH. Sediments were not collected in Year VIII. Table 2 depicts the sediment and oyster sampling at each site during the eight sampling years. Years I and H Sampling Summary Two sites (ECSP and ESBD) were completely devoid of oysters. ECSP was dropped from further consideration due to the lack of a nearby alternate and no chance of oyster. populations being restored at the site. CCIC was substituted .for ESBD, although ESBD was re-checked again in Year Il. CCIC's oyster population was buried by dredged material in Year II; thus, it too was a non- producing site in Year II. The sites at which we had collected oysters in Years I and II, but which may not sustain long term collection due to their sparse populations, included M13LR, TBHB, CBSR, and SAVV`B. Obtaining sediments with less than 80% sand was a problem at a number of sites. This was rectified for some sites in Year 11 by moving further from the oyster site and through more diligent searching. Those sites which 26 were unlikely to provide sufficiently fine sediments with environmental relevance to the oyster site included CBBI, SAWB, NBNB, TBHB, TBMK, TBPB, APCP, and APDB. Year M Sampling Sununary In Year III, twenty sites were added to the original list of 51 sampling sites, bringing the Year III site total to 71 sites. Sediments and oysters were collected from all of the additional sites, with the exception of LPGO, which had no oysters. These new sites are listed below: MBHI - Mobile Bay, Hollinger's Island CBFM - Charlotte Harbor, Fort Meyers PBPH - Pensacola Bay, Public Harbor PCMP - Panama City, Municipal Pier SWRP - Suwanee River, West Pass TBOT - Tampa Bay, Old Tampa BBTB - Barataria Bay, Turtle Bay CLLC - Lake Charles, Calcasieu Lake LBNO - Lake Borgne, New Orleans LPGO - Lake Pontchartrain, Gulf Outlet MRPL - Mississippi River, Pass A Loutre MRTP - Mississippi River, Tiger Pass ABHI - Aransas Bay, Harbor Island BRFS - Brazos River, Freeport-Surfside CCBH - Corpus Christi, Boat Harbor GBOB - Galveston Bay, Offatts Bayou GBSC - Galveston Bay, Ship Channel. LMPI - Laguna Madre, Port Isabel MBCB - Matagorda Bay, Carancahua Bay MBDI - Matagorda Bay, Dog Island Four sites in the Lavaca and San Antonio Bay system had no oysters for sampling in Year III. Massive die-offs occasioned by excessive freshwater runoff into the bays the previous year resulted in no oysters being obtained from the SAPP, SAMP, ESSP and MBLR sites. The absence of oysters was confirmed in conversations with Texas Parks and Wildlife, who indicated that the die-offs were confined to the Matagorda and San Antonio Bays, but that the effects were far more widespread than our sampling would indicate. At the same time, oysters began to reappear at Bill Days Reef (ESBD), resulting in the first collection of oysters from this site. Z7 Table 2. Sediment and Oyster Sampling Years I - VIII.

Problems in finding sufficient oysters at the Alafia River (TBHB) site in Tampa Bay continued in Year III to the point that all oysters at the site were collected, but not enough were present for all replicates. It was. recommended that this .site be removed or deleted in Year IV because of the continued problem in finding sufficient oysters. Year IV Sampling Summary In Year IV, a total of 67 sites were sampled. The sites sampled included the original list of sites in Years I and II, some sites first sampled in Year III, and seven new sites that were sampled for the first time in Year IV. Sediments and oysters were collected from all of the new Year IV sites except one. below. Those sites deleted from and added to the Year IV sampling are listed Sites Deleted from Samplin LMPI - Port Isabel, Laguna Madre, Texas CCBH - Boat Harbor, Corpus Christi, Texas ABHI - Harbor Island, Aransas Bay, Texas MBDI - Dog Island, Matagorda Bay, Texas MBCB - Carancahua Bay, Matagorda Bay, Texas ECSP - South Point, East Cote Blanche, Louisiana BBTB - Turtle Bay, Barataria Bay, Louisiana LPGO Gulf Outlet, Lake Pontchartrain, Louisiana LBNO New Orleans, Lake Borgne, Louisiana SRVVT West Pass, Suwanee River, Florida TBHB Hillsborough Bay, Tampa Bay, Florida Sites Added to the Samlin LMAC - Arroyo Colorado, Laguna Madre, Texas BRCL - Cedar Lakes, Brazos River, Texas AESP - Spring Creek, Apalachee Bay, Florida PCLO - Little Oyster Bay, Panama City, Florida CBJB - Joe's Bayou, Choctawhatchee Bay, Florida TBKA - Peter O'Knight Airport, Tampa Bay, Florida TBNP - Navarez Park, Tampa Bay, Florida Three of the Texas sites, which had no oysters in Year III due to the freshwater induced die-off, again had no oysters for collection in Year IV. These sites were in San Antonio and Espiritu Santo Bays (SAPP, SAMP, ESSP). Extensive effort was made to sample the sites, but only a few spat, too small and too few for collection, were found. Indications were good that the populations would recover sufficiently for Year V sampling. In Year III, the Lavaca River site (MBLR) also had no oysters and it was moved in Year IV to a more favorable position. The new site designated in the lower Laguna Madre at the Arroyo Colorado also yielded no oysters. Further surveys around Port Mansfield also came up without oysters. Thus, it was not possible to sample from the new site designated in the lower Laguna Madre. Oysters from three stations were collected at all sites where there were oysters except at the Pass A Loutre site on the Mississippi River (MRPL). Two and a half hours of dredging did not provide sufficient samples for three replicate sites of 20 individuals. per site. This low productivity, adverse and worsening weather, and one total engine failure combined to result in a short site (not enough replicates for all analyses). Year V Sampling Summary Seventy-one sites were sampled in Year V. The original list of Years I and Il sites, as well as sites established in Years III and IV, and four new sites were sampled for Year V. Sediments and oysters were collected from all of the new Year V sites. below.

Two of the Texas sites had no oysters in Year V and were not collected. These sites were in San Antonio and Matagorda Bays (SAMP and MBGP). Sites sampled in place of these two sites were MBCB and CCBH. Two sites in San Antonio and Espiritu Santo Bays (SAPP and ESSP) were sampled for the first time in two years. In Year IV, an unsuccessful attempt was made to establish a site in the Laguna Madre at the Arroyo Colorado. In Year V, oysters were located and the site was sampled. One new site was established in Mobile Bay north of the Dog River (MBDR). An attempt was made to locate a new site on the east side of the bay at Great Point (MBPG). However, no oysters could be found, so the site was not established. Another new site in Florida was established at Sabine Point in Pensacola Bay south of both of the existing sites. The northernmost site in Pensacola Bay at Indian Bayou (PBIB) yielded no live oysters. Year VI Sampling Summary Sixty-four sites were sampled in Year VI. The original list of Years I and II,sites were sampled, as well as sites established in Years III and IV. Two new sites were established for Year VI. Oysters were collected from all of the new Year VI sites, but sediments were only collected at the two new sites. Those sites deleted from and added to the Year VI sampling are listed below.

Two of the Texas sites scheduled for collection , CCNB and ESBD, had no oysters in Year VI and were not collected. CCBH was checked as an alternate site but it was also devoid of oysters. MRPL was not collected due to sparse collections there last year and extremely high water levels in the Mississippi River during the sampling period. Two new sites were established this year. A previous attempt to collect oysters at Lake Pontchartrain had been unsuccessful. But this year a new site in Louisiana, LPGO, was established in the lower part of Lake Pontchartrain. A second new site was established in the Florida Keys. Oysters were not present in the Keys, therefore an alternate bivalve species (Jewel Box, Chama sinuosa) was collected for analysis. Year VU Sampling Summary Sixty-seven sites were sampled in Year VII. The original list of Years I and II sites were sampled, as well. as some sites established in Years III and IV. Two new sites in Florida and three new sites in Puerto Rico were established in Year VII. Oysters were collected from most of the sites that were sampled during Year VI. Sediments were collected only at the five new sites and one old station in Florida (PBPH). Those sites deleted from and added to the Year VII sampling are listed below.

TEXAS SITES SITE NUMBER - 1 DESIGNATOR - LMSB SITE - SOUTH BAY, LOWER LAGUNA MADRE, TX NONIINAL SITE CENTER - 26002.77N 97010.48rW LOCATED ON NOS CHART # - 11302 SITE ACCESS - A tunnel hull outboard fishing boat and captain are generally chartered at the White Sands Marina in Port Isabel. In Year IV, a GERG boat was launched at the public boat ramp on South Padre Island at the Isla Blanca Pier. Travel time to South Bay is about 25 minutes. Landmarks used to locate the reef are 145' from the middle of the causeway bridge and 90' from the navigational range marker. The water depth is very shallow and requires the uise of a shallow draft vessel. SITE DESCREPTION - The oysters were located in clumps on expansive intertidal mud flats south of Clark Island on the northeast side of South Bay and were fully exposed at low tide. The dense clumps were mostly conglomerations of dead shells. The few live specimens were small, thin-shelled oysters interspersed among the empty shells. The reef contained many dead shells, and collecting a sufficient number of suitably sized oysters required searching and picking through the clumps of shells. OYSTER COLLECTIONS Years I, II, & III - There was no significant geographic distinction in the three stations. All three stations were taken from the middle of the reef. Year IV - Stations were collected in the same general location but were separated. Station 1 was taken at the north end of the reef just south of Clark Island and adjacent to the Spartina alterniflora marsh. Station 2 was approximately 75 m. to the south at two small reefs about 10 m apart. Station 3 was at the south end of the reef, 100 m. south of the middle part of the reef. Year V - Oysters were much larger and more abundant than previous years' collections. Stations were on the same reef but were separated. Station 1 was on the northeast shoreline. Station 2 was 100-200 m. south (toward the duck blind) from Station 1. Station 3 was another 100-200 m. south. Year V1, V11, &V111_ - Oysters were collected at the same locations as sampled the previous three years. SE )IMENT COLLECTIONS Years 1, 11, & III - Sediments were collected during the first three years of the study. Sediments were taken from the middle (Station 1), west end (Station 2), and east end (Station 3) of the reef. Years IV, V, V1, V71, & VIII - No sediments were collected during these years. SAMPLING METHODS Oysters - hand Sediment - hand WATER DEPTH - intertidal, 0.3 m POSSIBLE CONTAMINANTS - There were no obvious sources of contamination in the vicinity of the reef, although the salinity of the bay was high and the oysters endured exposure out of the water for a considerable period during the day.

SITE DESCRIPTION - This collection site, which was established and collected only in Year III, was located along the south jetty of the Queen's Point Marina. Oysters grow attached to the concrete bulkhead and are exposed at low tide. Numerous shells are present but a high proportion of the oysters found here were dead and the live oysters were thin-shelled. Careful handling was required while collecting to avoid breaking the live oysters. Typically, salinities are high throughout the year. OYSTER COLLECTIONS Year III - Discrete stations were sampled as described below. Station 1 was located on the breakwater extending south from the marina entrance. Station 2 was along the south facing bulkhead. Station 3 was located between Stations 1 and 2.in a cove formed by the two bulkheads. Years 1-V, V, VI & V11' - The site was not sampled during Years IV, V, VI, and VIII. SEDEVEENT COLLECTIONS Year I11- Sediments were collected outside the bulkheaded area opposite Station 1 on the side adjacent to the Brownsville Ship Channel.

Travel up the ICWW to the site. Travel time is 40 minutes. SITE DESCRIPTION - This collection site, established and collected for the first time in Year V, was located at cabins along the ICWW. Oysters grow attached to the concrete pilings and on mud flats which were exposed at low tide. OYSTEIt COLLECTIONS Year V - Station 1 was located at the first cabin #1399 (tan with brown trim), which was just north of channel marker 45 and west of Primero Island. Oysters were collected from the concrete piling supporting the cabin. Station 2 was at cabin #1423. The cabin was between channel marker-41 and channel marker 43. Station 3 was.located north of channel marker 41 at cabin #P1345. Oysters at this station were growing in clumps on the mudflat. Many were very large with smaller more suitably sized oysters attached. Year VI, VII, & VIII - This site was not sampled during these years. SEDRAEra COLLECTIONS Year V - Sediments were sandy silts which were tan on the surface which overlay a black layer mixed with shell fragments and sea grasses. These were collected at the cabins for Station 1 and 2. Station 3 sediments were collocated with the oysters on a -subtidal mudflat. Year VI & V11 - No sediments were sampled during this year.

There is a boat launch at the Gunderlands Boatland. Collection stations are located along the shoreline on the north side of the road. SITE DESCRIPTION - The site was located 100 in from the boat ramp at bearing 325'. The bay was very shallow with exposed reefs. These reefs had mainly dead oysters. Small thin-shelled oysters were collected along the mud shoreline or on pilings. Oysters were intertidal and seemed to be on the decline. OYSTER COLLECTIONS Years 1, 11 & III - Oyster collection stations were as follows: Station 1 - 145' to boat ramp; 213' to the top of the Corpus Christi bridge. Station 2 - 25' to Portland water tower; 208' to the top of the Corpus Christi bridge. Station 3 - 25' to Portland water tower; 115' to large pilings at Gunderlands. Year IV - Oysters were collected in Year IV at the same location as in previous years. The three stations were 40 to 50 m apart. It was noted that the population was more abundant than had been observed in the last two years. Year V - Oysters were collected along the shoreline at the same general locations as previous years. Station 1 was adjacent to the boat ramp. Station 2 was 50-m to the south and Station 3 was another 50 m to the south toward the bridge. Year V1' - We attempted to sample the same location, but no live oysters of collectable size were available. A few spat in the 1 to 2 cm size range were observed. No samples were collected. Year VII - Oysters were collected along the shoreline in the same general locations as in Year V. Year VIII - Oysters were small and extremely hard to find. IDMENT COLLECHONS Years I, II, & III - Sediments were collected adjacent to each oyster station. Sediments for the NIST archive were also collected adjacent to the oyster stations. Years IV, V, VT VII, & WI1 - No sediments were sampled during these years. SAMPLING METHOD Oysters - hand Sediment - hand WATER DEPTH - 0.2 m POSSIBLE CONTAMINANTS - Contamination factors included the boat ramp, marina, Rincon Industrial Park to the west, and Corpus Christi Ship Channel to the south.

SITE NUMBER - 3 DESIGNATOR - CCIC SITE - INGLESEDE COVE, CORPUS CHRISTI TX NOMINAL SITE CENTER - 27050.28rN 97014.28W LOCATED ON NOS CELART 11309 SITE ACCESS - To reach the site a boat is launched at the public boat ramp at Ingleside-On-The-Bay. A 5 minute ride across the La Quinta Ship Channel and Ingleside Cove is required to reach the site. SITE DESCRIPTION - The site was located along the west side of Ingleside Cove channel and north of Ingleside Point on the south tip of the spoil island. Oysters were located on an exposed reef and on a mud flat that was exposed during normal low tides. The site was surrounded by submerged seagrass beds. Landmarks to locate the site were Ingleside Point to the south and the dredge spoil island to the north. OYSTERCOLLECTIONS Year I - The three stations sampled for oysters were located on a tidal reef and on a mud flat. Station 1 was at the center of the reef. Station 2 was from the end nearest the shore, and Station 3 was at the south end of the reef. Year Il - No oysters were found in Year II and Corps of Engineers surveyors reported that the area had been recently dredged. Oysters were either moved or buried in Year 11. Year III - There was no significant geographic distinction in the three stations. Oysters were present again during Year III. Most of the oysters present in Year III were very small and appeared to represent a population that had been newly established since the die-off during Year II. Year I-V - In Year IV the stations were the same as those sampled for Year III. Year IV oysters were small and sparsely scattered. Years V, VI and WI - Sampling sites were in the same locations as previous years with Station 1 in the center of the reef, Station 2 toward the shore 75 m from #1, and Station 3 was 70 m south of #2. Years W11 - Only three small oysters were found on this reef, so no samples were taken. SEDIME1W COLLECTIONS Years I, II, & III - Each year sediment samples were collected 30 m offshore to the west from each of the oyster collection sites. Submerged seagrasses were present in some of the sediments. Sediment samples only (no oysters) were obtained in Year Il at locations sampled in Year I. Years IV & VI - No sediments were sampled during these years. Year V - Sediments were collected adjacent to each of the oysters stations, approximately 15-20 m offshore. Sediments were primarily sand, shell, and grass with sparse areas of mud. Years V11'& WII - No sediments were sampled these years. SAMPLING M[ETHOD Oysters - hand Sediment - hand and box core WATER DEPTH - 0.3 m intertidal POSSIBLE CONTAMINANTS - Contamination was probable from dredging, barge traffic in the La Quinta Channel and from a nearby aluminum plant.

The site is reached by exiting off of U.S. Highway 181 at Corpus Christi and driving under the bridge as if going to the boat harbor north of the Corpus Christi Ship Channel. SITE DESCRIPTION - This collection site was established in Year III. The site was located under the bridge (Highway 181). Oysters occurred along the shoreline and were attached to concrete and brick rubble. There were both single oysters and clumps. The bottom was a mixture of sand, shell, mud, trash, and concrete rubble. OYSTER COLLECTIONS Year III - Station 1 was located along the shore in shallow water on the northeast end of Rincon Point directly under the Highway 181 bridge. Station 2 was located along the next 100 m section. Station 3 was located farther east along the shoreline adjacent to a trailer park. Year IV - The site was not sampled. Year V - Sampling stations were located at the same sites originally established in Year III. This site was collected this year as an alternate site, since oysters were unavailable at another site. Year VI - There were no live oysters present at the site this year, therefore no collections were made. Years VII & V111 - The site was not sampled. SEDDH2qT COLLECTIONS Year III - Sediment was collected 10 to 20 m offshore of each of the oyster collection stations.

SITE NUMBER - 4 DESIGNATOR - ABLR SITE - LONG REEF, ARANSAS BAY TX NONONAL SITE CENTER - 28002.96'N 96056.77W LOCATED ON NOS CE[ART # - 11314 SITE ACCESS - The site is located across Aransas Bay almost due east from Fulton. To reach the site, launch at the public boat ramp near the harbor. Travel across the bay to the ICWW and then turn northeast until channel marker 25 is reached. The reef extends from St. Joseph Island into the bay. SITE DESCRIPTION - During the first four years of the study, all three stations were located on the reef which extended from St. Joseph Island toward channel marker 25. Oysters were collected by hand from the exposed intertidal reef wl-Ach was composed mainly of dead shell. The site was located at Lat. 28'03.88'N and Long. 96'57.80'W for the first four years. In Year V the site was moved due to a lack of oysters. OYSTER COLLECTIONS Years I & Il - Oyster stations were located south of the ICWW. Station 1 was on the first island south of channel marker 25. Bearing to landmarks were 255' to white water tower at Rockport and 305' to the middle of the causeway bridge. Station 2 was on the next island to the south at 320* to ICWW marker 25 and 245' to white water tower.. Station 2 was located on an island that was a designated bird rookery. Station 3 was on the next island south at 305' to the middle of the causeway bridge and 240' to the white water tower. Year III - Few oysters were present in Year III and no young oysters were observed. Due to the sparse oyster population available by hand, it was recommended that future collections be made by tonging or dredging in deeper water. Year rV - The collection stations for Year IV were the same as those of the first three years. Year IV oysters were tonged in approximately 0.5 m water on the west side of the island. Year V - Live oysters could not be located at the previously collected locations, so the site was moved along the reef closer to the shore and approximately I mile to the southeast. Stations were separated by 100 rn along the reef. Years V1, VII & V711 - The site collected in Year V was reoccupied and sampled in Years VI, VII, and VIII. 89 SEDIMENT COLLECTIONS Years I & 11 - Sediments were collected by box core from the east side of the reef in deeper water in the same order as the oysters. Year III - Sediments were collected on the west side of the reef approximately 200-m off the reef from each oyster station. Year IV - Sediments (NIST) were collected on the west side of the reef approximately 200 m off the reef from each oyster station. Years V, VI, VII, & VIII - No sediments were collected these years. SAMPLING METHOD Oysters - hand and tongs Sediment - box corer WATER DEPTH - intertidal, 0 - 0.5 m; subtidal, 0.8 - 2 m, (Year I).

The site is at-a public access area near fishing piers and is reached by crossing the Port Aransas ferry and traveling west past the University of Texas Marine Sciences building to the end of the paved road. The site is north of the sand parking lot. SITE DESCRIPTION - Oysters were attached to rip rap and rubble material around the base of the piers. Oysters were generally small and not abundant; collections would be best made at low tide since the oysters were growing on bottom rubble. OYSTER COLLECTIONS Year I11- Station I was located west of the wooden pier. Station 1 was located 200 m to the west. Station 2 was east of the wooden pier. Station 2 was 275 m to west. Station 3 was located 75 m east of Station 2 and west of the three concrete ship docks. Station 3 was 325 m to the west of the wooden pier. Years rV, V, VI, VII & V111 - This site was not sampled during these years. SEDIM]ENTCOLLECTIONS Years Iff - Sediment at the oyster site was predominantly sand; therefore, the sediment stations were established 200 m to the west of the oyster stations. Station 1 was a sand and clay bottom 200 m east of Oyster Station 1. Stations 2 and 3 were 50 and 100 m farther to the west. Years IV, V, V1, VII, & VIII - This site was not sampled during these years. SAMPLING AEffMODS Oysters - hand Sediment - hand WATER DEPTH - intertidal, 0 - 0.4 m POSSIBLE CONTAMINANTS - Numerous potential sources of contamination existed at this site.

A boat must be used to reach the site and is launched at Pouzee's Marina, at Lone Tree Point, Rockport. From Pouzze's, go northwest to Copano Reef, an exposed intertidal reef. SITE DESCRIPTION - The reef ran southeast from Copano Point and was located around the white pole with Texas Parks and Wildlife marker "Copano Reef." This reef has been on the decline for the past five years. Oysters are small and sparse. OYSTER COLLECTIONS Years I & Il - Station 1 was 100 m north of the Texas Parks and Wildlife marker, closest to the shoreline. Station 2 was adjacent to the marker. Station 3 was 100 m south of the marker. In the first two years of the project, there were abundant oysters which were collected by hand. Yea r III - Year III, there were few live oysters due to prolonged freshwater conditions during the spring. Numerous oysters were present which had died during the past season, and no young oysters or spat were observed at the site in Year III. Year IV - In Year IV, oysters were collected at the same locations as sampled the previous three years. Year IV oysters were very small and difficult to obtain. Year V & VI - Oysters were collected along the same segment o f the reef as previous years. Oysters were abundant this year. Year VII - Oysters were collected along the same segment of the reef as in previous years. Oysters were not abundant. Most were very small and many were dead. Year VIII - The reef was dead, so no oysters were collected. SEDDIENT COLLECTIONS Years 1, 11, & III - Sediments were collected in subtidal areas in 1 to 1.5 m water and approximately 50 - 100 m west of the respective oyster sample area.

In Year 111, the boat was launched at Goose Island State Park and in Years IV and V the boat was launched at Port O'Connor. Regardless of where the boat is launched, run time to the site is at least an hour in good weather. SITE DESCRIPTION - This site was located on the north side of Mesquite Bay between Matagorda Island to the southeast and the Aransas National Wildlife Refuge to the north. The reef was oriented in a northwest-southeast direction and the site was located in the middle of the reef at Ayres Dugout. OYSTER COLLECTIONS Years 1, 11, 111, 1-V, V &W - Oysters and sediments were collected by hand on the intertidal reef at the same stations each year. During some years, the reef silted over but oysters were still present. Station 1 was on the east end of the Dugout Cut. Station 2 was in the middle of the Dugout. Station 3 was on the west portion of the Dugout. There was an abundant supply of large oysters. Year VII - Oysters were collected at the same stations described for previous years. This year oysters were mostly dead and there waslittle indication of reproduction. Year VIII - No live oysters were found at last year's location, so the site was moved -0.25 miles to the south. The site is located on a small brushy island with a red reflector on a post. Site coordinates (GPS) for this year's collection are Lat. 28* 09.82N and Long. 96149.96 `W.

REEF, SAN ANTONIO BAY TX NOMINAL SITE CENTER - 28014.00'N 96042.55W LOCATED ON NOS CE[ART # - 11315 SITE ACCESS - To reach the site a boat is launched at Seadrift (Haynies Seafood or the Public Ramp at Swan Point), Port O'Connor (Doc's Doc) or Port Lavaca. Run time.. by boat from Seadrift is 30 min, 2 to 3 hours from Port Lavaca, and 1 hour from Port .O'Connor. The site is located on the reef that extends to the northwest off Of Panther Point. SITE DESCRIPTION - This submerged reef was located 300 to 400 m. from a production platform at a bearing of 2600 and 100 m from the black and white PVC pole marking the top of the reef. This subtidal reef was located to the northeast and east side of the white plastic pole off the northwest end of Panther Point. Oysters and moderately dense "grass beds" were widely dispersed on the sandy bottom. OYSTER COLLECTIONS Years I & 11 - Samples. during Years I and II were collected by dredge but could be collected by tongs in calm weather. Oysters were numerous in the first two years. Station distinctions were not made. Year III - There were no oysters present at this site or any of the reefs in the nearby areas. Local and state biologists reported that all of the reefs were dead due to prolonged freshwater conditions during the spring. The submerged seagrasses and seaweeds normally present were absent. Year IV - As in Year III, there were no collectible oysters present due to the massive die-off in the San Antonio and Lavaca Bays in the spring of 1987. Spat in the size range of 0.5 to 0.75" were observed but were not numerous. In the absence of another major physical stress, there will probably be oysters next year. Year V - Station 1 was on the submerged reef on a bearing of 2800 to the production platform. The bottom was shell with sandy silt. Oysters were tonged. Station 2 was 100 m to the southeast (bearing 150') between the two white poles on the west side of the reef. The site was subtidal but the oysters were collected by hand in water only 0.2 m deep. Station 3 was another 200 m south (bearing 1500). Oysters were tonged at this location. Oysters at all three stations were mixed with abundant shell and marine algae. Year V1 - Oysters from all three stations were collected by hand at Year V's Station 2. All stations were collected in one location due to broken oyster tongs. 113 Year V11 - Oysters were collected with a dredge from the top of the submerged reef. Collections were made at the same locations described for Year V. Station 1 was on the North end of the reef. Station 2 was on the midsection in shallow water. Station 3 was on the south end of the reef . Year V111 - Oysters were very scarce at this reef. All the oysters were collected along the reef top near station 2. Stations were not distinguished due to the small number of oysters present. SEDIMENT COLLECrITONS Years I, II & III - Sediments were collected at the same stations where oysters were located. Years IV, V, V7, VIT & VIII - No sediments were sampled during these years. SAMPLINGMETHOD Oysters - dredge, tongs, and hand Sediment - box core WATER DEPTH - subtidal, 0.2 to 1.5 m. POSSIBLE CONTAMINANTS - A nearby possible source of contamination was an oil or gas platform bearing 2600 from the reef, 0.25 to 0.5 mile distant. ENVIRONMENTAL DATA Salinity Temperature Dates.

Run time by boat from Seadrift is 30 min, 2 to 3 hours from Port Lavaca, or I hour from Port O'Connor. From Swan Point, near Seadrift, exit the channel which is very shallow at low tide and proceed- southeast in the Victoria Barge Canal to channel marker 15. At marker 15, turn southwest to the exposed reef There are no landmarks on shore for reference. SITE DESCRIPTION - The site was located off Mosquito Point west of the Victoria Barge Canal and southwest of channel marker 15. Oysters were collected on the exposed intertidal reef A six legged wooden platform was located 80 m to the southeast of the reef. OYSTER COLLECTIONS Years I & 11" - Oysters were abundant at this location during Years I and II. Station 1 was at the midpoint of the exposed reef, Station 2 was 150 yds south on the west side, and Station 3 was another 200 yds south of Station 2. In Year II, the station order was reversed with Station 1 on the west end of the reef, Station 2 was 200 ft to the east, and Station 3 was another 200 ft east. Year III - In Year III, there were no live oysters present on the reef and no spat or young oysters were observed. Year rV - As in Year III, there were no live oysters present due to the massive die-off in the San Antonio and Lavaca Bays in the spring of 1987. Year V - Still no oysters alive on this reef. No samples were collected this year. Year V1 - Oysters were again present. Collections were made on the reef southeast of Mosquito Point. Station 1 was on the north end of the reef, Station 2 was on the middle part of the exposed reef, and Station 3 was on the southwest end of the reef. Year V11 - Oysters were collected at the same locations described last year. Oysters were much more abundant this year. Year VIII - The reef was dead; therefore no oyster samples were available this year. 119 EDIMENTCOLLECTIONS Years I and Il - Sediments were collected in subtidal areas adjacent to the oyster stations from mud and sand bottom in Years I and IL Station 1 was on the west side 10-50 feet out. Station 2 was 50 yards south of Station 1 (intertidal) and 200 yards south was Station 3. Year III - Sediment samples were collected from soft sandy mud bottom over shell hash approximately 100 to 200 m north of the reef in 1 to 1.5 m of water. Years rV,..V, VI, VII, & VIII - No sediments were sampled during these years. SAMPLINGMETHOD Oysters - hand Sediment - box core WATER DEPTH - intertidal, 0 - 0.5 m POSSEBLE CONTAMINANTS - No.contaminants were observed but the potential for contamination existed since the site was located within a half mile of the Victoria Barge Canal.

Proceed southeast on the Victoria Barge Canal to the ICWW and then east to the site. Alternate launch points are Snapper Snatcher dock or Doc's Doc in Port O"Connor. South Pass Island, a few hundred meters to the southeast of the site, is an oil production site and has a compressor station and buildings. Approximate time to the site is 0.75 hrs. SITE DESCRIPTION - The site was located between Grass Island on the north and Steamboat Island on the south. The site was composed of a series of low exposed reefs at 105' from pumping station, 2400 from water tower and 150' from southeastern most point of Steamboat Island. The sample area was an intertidal reef. OYSTER COLLECTIONS Years I & 11 - Oyster collection areas were 100 m apart on a north-south line along the exposed reef. Oysters were abundant during both years. Year III - In Year III, there were no oysters present. Texas Parks and Wildlife biologists reported that the reefs in Espiritu Santo Bay had died due to excessive freshwater inflow during the spring and summer periods. Year IV - As in Year 111, there were no collectible oysters present in Year IV due to the massive die-off in the San Antonio and Lavaca Bays in the spring of 1987. Spat were observed but were not numerous. In the absence of another physical stress, there will probably be oysters next year. Years V & V1 - Oyster were present in adequate numbers. Station 1 was on the reef which was northwest of the tanks and west of the island where station 3 was located. The three tanks at the production facility were located on a bearing of 130'. Station 2 was north of the production station, to the east of Station 1 on the same island. It was 1800 to the channel marker pole and the top of the small island was to the west. Station 3 was northeast of the tanks on the end of the island with the top always exposed and in line with the island with the Yuccas. There were abundant shell, shell hash, and small oysters with attached marine algae. Year VII - Collection sites were in the same locations as the last two years. Year VIII - The reef was dead; therefore, no oysters were collected. 125 IDMENTCOLLECTIONS Years I, II & Iff - Sediments were taken from subtidal mud 500-1000 m to the north at three random stations in all years. Sediments were loose gray muds overlain with loose brown mud. Years IV, V, VI& VII - No sediments were sampled during these years. SAMPLINGMETHOD Oysters - hand Sediment - box corer WATER DEPTH - intertidal, 0.1 - 0.5 m POSSIBLE CONTAMINANTS - Contamination factors included oil and gas pipelines and marine traffic.

SITE DESCRIPTION - The site was located at Bill Days Reef which was in Barroom Bay south of Port O'Connor. The reef was oriented almost east-west. During the first two years of the study there were no live oysters. OYSTER COLLECTIONS Years I & Il - The site was visited both in 1986 and 1987 and no living oysters were found. Year III - During Year III, live oysters were found. Oysters were collected by hand on the exposed portion of the south side of Bill Days Reef in intertidal water near the northernmost duck blind at the east end of the reef. No distinct stations were established. Oysters were very small but were numerous. Abundant spat were present. Year IV - Oysters were again present with small oysters in clumps on dead shells. In Year IV, stations were established. Station 1 was on the west end of the reef at bearing of 360' to Port O'Connor water tower; 340' to Nhlchem tanks; 250 m south of the reef-, Station 2 was 100 m to the east in the center of the reef on a line with the west end of Bill Days Reef and the tall tower to the west; and Station 3 was 50 m to the east. Year V - Stations which were established in Year IV were sampled again. Oysters were abundant but small. Year VIT - No oysters were present in the required size range but a few 1 to 2 cm oysters were present. Collections were not made at this site.

The site was moved in Year IV. The new site is accessible from Highway 35 and can be sampled entirely by hand. SITE DESCRIPTION - The original site was a submerged reef approximately 0.5 mile west of the river mouth. The highway 35 bridge was to the south and the plastics plant to the east. The site was an exposed reef on the east side of the channel entering the Lavaca River. Oysters were located only on the west side of the reef between channel marker 22 and the river mouth to the north. Most of the reef was dead and oysters were sparse. The site was originally located at Lat. 28'4,1.00'N and Long. 96*34.65'W. In Year IV, this site was moved because of the difficulty in finding oysters in Year III and the absence of oysters in Year IV at the original location. The site was moved to the north shore of the causeway where it joins.the Highway 35 bridge. OYSTER COLLECTIONS Year I - In.Year I the oysters were collected by tonging from a subtidal reef west of the river mouth. Station bearings were: Station 1 was 185' to the middle span of bridge; 901 to the water tower at plastics plant. Station 2 was 85' to the water tower at plastics plant; 195' to the middle span of the bridge. Station 2 is 0.25 mile south of Station 1. Station 3 was 230' to the middle span of the bridge; 70' to the water tower at the plastics plant. Station 3 was 0.25 mile south of Station 2. Year II - No distinctions were made for Stations 1, 2, and 3 during Year 11. Oysters were collected by hand. The reef could not be relocated in Year II; therefore, there was a slight difference in site location by approximately 500 to 1000 m between Years I and II. Year III - No oysters were present in Year III. Conversations with Texas Parks and Wildlife biologists indicated that the reef die-off was due to prolonged freshwater inflow. Year rV - Station 1 was located at the end of the causeway. Station 2 was located approximately 300 m east of Station 1, where a spit/reef extended into the bay from the shoreline. Station 3 was approximately 400 m east of Station 2. Commercial oystering was observed just north of the bridge, between the center span and the power lines to the north. 137 Years V, V1, VII, & VIII - Oysters were collect ed in the same locations as described for Year IV. Oysters were numerous each year. SE )IMENT COLLECTIONS Years I, II & Iff - Sediments were collected with a boxcorer at stations spaced equidistant and extending from channel marker 22 to the river mouth. Sediments for the NIST archive were collocated with the oysters. Years IV, V, VI, VII & VIII - No sediments were sampled during these years. SAMPLINGMETHOD 0 sters - dredge, tong or hand y Sediment - box core WATER DEPTH - 0.2 - 2 m, subtidal (Years I & II), intertidal (subsequent years) POSSI]BLE CONTAMINANTS - Possible contamination could be from the plastics plant to the southeast of the site and the Alcoa plant some distance to the south in Lavaca Bay.

SITE DESCRIMON - This site was a submerged reef approximately 400 m off the north shore of Gallinipper Point. The reef ran on a line from the aluminum plant to a house on the shoreline that had an asymmetrically pitched roof and a fireplace chimney. The reef was south of channel marker 63 and was approximately 400 m offshore. OYSTER COLLECTIONS Years I & Il - In Years I and II, the stations were distributed on the reef line at distances of 200, 300, and 400 m from shore. Station bearings were: Station 1 - 360' to the orange/white range tower; 2750 to the twin radio towers. Station 1 - 50 m from the high range marker. Station 2 was 3250 to tower with range light; 290' to the twin radio towers. Station 2 was 400 m from the shore. Station 3 - 30' to tower with range. light; 285' to the twin radio towers. Station 3 was at the eastern end of Alamo Beach. Oysters were dredged using a commercial boat. Year III - In Year III the oysters were purchased from commercial fishermen with Stations 1 and 2 located in approximately the same areas but Station 3 was a mix of Stations 1 and 2 oysters. The reef supported many live, good sized oysters. It was not fished commercially or privately during the first two years, since it was rumored to be a closed area due to pollution. There were numerous oyster boats dredging in Year III. Year I-V - In Year IV, the same three sites were dredged as were sampled in Year II. Oysters were dredged by a commercial oysterman at our request and direction. Year V - The same areas and numerous adjacent sites were examined for oysters but none could be located; therefore, an alternate site, which had previously been sampled, was selected in another bay system. Year VI - Oysters were present again this year. Oysters were collected with a clam dredge. Station 1 was 100 to 200 m from the shoreline on a line between the geodesic dome house and the range marker. Station 2 was 150 to 200 m to the north along the same line. Station 3 was another 100 m to the north, directly south of the range marker. 143 Year V11 & VIII - Oysters were present these years and collections were made in the same location as described for Year VI. )IMENTCOLLECTIONS Years I, II & III - Sediments in Years 1, 11 and III were obtained by boxcore from an area northwest of the reef between the high range marker and Alamo Beach. Years IV, V, VT V11, & VIII - No sediments were sampled during these years. SAMIPLINGMETHOD Oysters - The site required dredging on a completely subtidal reef. Sediment - box core WATER DEPTH - subtidal, 2 m POSSIBLE CONTAMINANTS - Possible point contamination sources were the Alcoa aluminum plant directly across the bay, and the plastics plant near the Lavaca River mouth.

The transit across Lavaca, Matagorda, and Palacios Bays takes 1.5 hours. In Year III and subsequently, the boat was launched at the public boat ramp at Palacios a-nd then proceeded southwest out the Palacios Channel for two nautical miles to channel marker 48 and then south-southeast across the bay to the northeast end of the Coon Island Reef (15 minute run time). SITE DESCRIPTION - The site was located on a string of reefs across the mouth of Green Island Bay. The reef extends from. Coon Island to Oliver Point. Station 1 at the north end of the reefs was closest to Palacios. OYSTER COLLECTIONS Years 1, If, 111, IV, V & VI - Oyster collection stations remained the same during each year of sampling. Station 1 was on the north side of Coon Island (the northernmost of three exposed islands/reefs running from Oliver Point to the northeast). Station 2 was taken from the westward end of the middle island, between Stations 1 and 3, and is due east of Red Chi #2. Station 3 was closest to Coon Island at the westernmost reef/island (samples from the north side and east end of this island). Station 3 was on -a bearing of 150 degrees to the platform. Year VI - Sample sites remained the same as in previous years. A new channel marker (red 2) had been installed which provided an additional reference point. Year VII &, V111 - Oyster collection stations were the same as the previous seven years. Oysters were not as abundant this year. SEDD4ENT COLLECTIONS Year I - Sediments were collected by hand in close proximity to the oyster sites. Years 11 & III - Sediments were collected by boxcorer at stations located 150- 200-m, southwest from the oyster stations. Years IV, V, V1, VII & VIII - No sediments were sampled during these years. 149 SAMPLINGMETHOD Oysters - tong and hand Sediment - hand and box corer WATER DEPTH - intertidal, 0 to 1 meter POSSIBLE CONTAMINANT'S - There were no obvious sources of contamination in the vicinity except for a couple of oil or gas production platforms. Natural contamination may have been present since the entire middle island smelled of bird droppings and the waters surrounding the reef had abundant -brown and green algae.

The public boat ramp located on the highway is silted in near the mouth so that only a small boat can be launched. Proceed directly south down the bay for 4.5 nautical miles and then turn to the east toward a point with a PVC marker. The site can also be reached from Highway 35 by turning south at the intersection of Highway 35 and 1862 onto Jackson County Road 476. Proceed on County Road 476 to County Road 477, turn south again and proceed to Bay Ave. Turn left on Bay Avenue and drive to the end of the road. The site is located approximately 100 yards to the west. SITE DESCRIPTION - The site was located on the east side of Carancahua Bay directly across the bay from Port Alto. Several houses were located on or near this point. The site was a shoreline site and could be collected from the shore at low tide. Oysters were very abundant at Stations 2 and 3 but were less so at Station 1. No live oysters were found in the upper part of the bay, presumably due to prolonged freshwater conditions which were common during the spring of 1987. OYS17ER COLLECTIONS Year III - Oysters were collected at this site for the first time in Year III. Station I was located approximately 300 m south of a green house along the shoreline. Station 1 was 10 to 20 m off the shoreline on a small reef paralleling the shore for approximately 80 m, oysters were found on the bottom or attached to shell. Station 2 was on the point which extended to the southwest. At this site the oysters were attached to concrete and brick rubble. The station extended approximately 100 m into the bay. Station 3 was located southeast of Station 2 on an intertidal reef along the shore and on an exposed reef approximately 20 m from the shore. Year rV - Oysters were not sampled during this year. Year V - This site was used as a substitute for MBGP. Oysters were abundant and were collected in the locations that were sampled during Year III. Years VI and VII - This site was not sampled during these years. Year VIII - This site was used as a substitute for dead reefs father south. Oysters were abundant and were collected at the locations sampled during Year V. 161 Years IV, V, V1, VII, & VIII - No sediments were sampled during these years. SAMPLING Affi'MODS Oysters - hand Sediment - box core WATER DEPTH - intertidal, 0 to 0.3 m POSSIEBLE CONTAMINANTS - No sources of contamination were obvious within the bay; however, the inflow and runoff into Carancahua Bay was from the adjacent agricultural lands which were a potential non-point source for pesticides and agricultural chemicals.

A boat launch is located at the end of the road on FM 2918. From the boat ramp proceed southeast across the ICWW to the entrance at Cedar Lakes. Then proceed west- southwest down the channel for approximately 0.75 miles to where two land masses converge, one from the north and one from the south. SITE DESCRIPTION - This site was located on the east side of the San Bernard National Wildlife Refuge near Rivers End, approximately 2 miles west of the San Bernard River. The site was south of the ICWW on the east side of Cedar Lakes. An old silted-in channel ran southwest off of the ICWW into Cedar Lakes. This area was predominated by very shallow bays with numerous oyster reefs surrounded by Spartina alterniflora marshland. OYS'rM COLLECTIONS Year rV - Station 1 was located 50 m southwest of the metal casing on the west side of the small channel which turned to the south. Oysters were collected by hand from an exposed reef on the west side of the channel. Station 2 was located approximately 150 m northeast of the metal casing and 200 m from Station 1. It was on the north side of the entrance channel. Oysters were collected by hand from both sides of the land mass which protruded to the south. Station 3 was located on the exposed reef which ran east-west and paralleled the entrance channel. The actual collection site was 350 m east of the metal casing and 200 m east-southeast of Station 2. Oysters were very abundant at this location but the sediment was soft which made access to the oysters difficult. Year V - Due to siltation of the channel leading to Station 1 it was moved 100 m to the east. . The station was located on the east side of the marsh that was directly south of Station 2. Oyster collections were made on the small bay to the south. Station 2 remained at the originally established sites. Station 3 was moved 100 m to the east for better access and better quality oysters. This station was located on the west bank of the small channel which went to the south and was approximately 300 m east of Station 1. Year V1 - Oysters at Station 1 and 2 were collected in the same locations as in Year IV. Station 3 was collected at the same location as last year, along the small channel on the south side of the channel approximately 300 m east of Station I and 2. Oysters were located on the west side of this channel. 173 Year V11 - Oysters were collected in the same area as last year but two stations were moved. Station 1 was moved approximately 50 m to the east toward Station 2. Station 2 was collected at the same location described for Year IV. Station 3 was moved across the channel approximately 50 m to the north of last years collection site. Year VIII - Oysters were collected at the same location as Year VII. SEDIMENT COLLECTIONS Year IV - Sediments were collocated with the oysters and were collected by hand from within the oyster bed. The sediment was red-brown soft silty mud. Year V - Sediments were again collocated with each of the oyster sites and were collected by hand. Sediment character was unchanged from last year. Years V1, V11, & VIII - No sediments were sampled during these years. SAMPLING AIETHODS Oysters - hand Sediment - hand WATER DEPTH - intertidal, 0 to 0.3 m POSSIBLE CONTAMINANTS - No obvious contaminants were observed, a potential source is marine fuel and oil from the ICWW.

From the intersection of FM 288 and 1495 drive south on FM 1495 to the ICWW, cross the draw bridge and the site is located along the ICWW and in the housing development with silted-in boat basins east of FM 1495. SITE DESCRIPTION - Oysters could be collected easily by hand at low tide, otherwise it was necessary to tong for bottom concrete rubble on which the oysters were attached. A local resident indicated that oysters were less abundant in Year III, but a moderate population existed at the three stations. OYSTER COLLECTIONS Year HI - Year III stations were established as follows: Station 1 was directly east of the highway along the conciete rubble on the south shoreline of the ICWW and continued inside the first boat basin along the west side of the bulkhead. Oysters were collected from concrete rubble and wood pilings on the mud bottom. Station 2 was located across the boat basin along the east side of the bulkhead. The oysters were attached to the concrete bulkhead and from concrete rubble on the mud bottom. Station 3 was located in the next boat basin to the east. Oysters were collected on the east side of the channel along the bulkhead and from concrete rubble on the mud bottom. Years IV, V, V1, V11', & VIII - Oyster stations were collected at the locations described for Year III. SEDIM]MW COLLECTIONS Years III - Sediments were collocated with the oyster stations. The bottom was soft red silty clay over black to gray mud. Years IV, V, VI, VII, & VIII - No sediments were sampled during these years. SAMPLING MEwMODS Oysters - hand and tongs Sediment - hand scoop and box corer WATER DEPTH - Water depth at all three stations was less than 1 m at high tide with a range of 0 to I m, intertidal. 179 POSSIBLE CONTAMINANTS - Contamination was possible from boat traffic in the ICWW and nearby oil and chemical refineries. Effluent from an adjacent dredge disposal site was returned to the ICWW through the second boat channel where Station 3 was located.

The site was moved in Year III to near the Judges Stand outside of the Houston Yacht Club. The site is accessed by boat launched at the Houston Yacht Club, Eagle Point Marina or Galley Restaurant Marina. SITE DESCRIPTION - The site was in the middle portion of Galveston Bay near Shoreacres just north of Red Bluff. In the first two years the site was along shore in front of the third house north of the yacht club, in from the retaining wall (Lat. 29'37.20'N, Long. 95'00.10'W). Oysters were intertidal and sediments were subtidal. Sediments were collected east of the Yacht Club property. Oysters were few in number and attached to rocks. In Year III, the site was moved. The new location at the Judges Stand was subtidal and oysters were more abundant. OYSTER COLLECTIONS Years I & II - Years I & II shoreline stations were as follows: Station 1 was 50 m north of the Yacht Club property. Station 2 was 70 m north of Station 1. Station 3 was 80 m north of Station 2. Year III - There were no oysters along the shoreline in Year III; therefore all three stations were moved to deeper water outside the entrance to the yacht basin. The reef was 2 to 3 m deep and runs south from the judges stand curving back to the shore. Station 1 was at the Judges Stand (a 4 piling platform 300 m outside the yacht basin. entrance). Station 2 was 100 m to the south and Station 3 was another 100 m to the south. Year rV - In Year IV all three oysters stations were collected by tong -at the Judges Stand (Station 1) due to rough weather conditions and siltation of the lower end (Station 3) of the reef. Year V - Oysters were collected from the reef around the Judges Sta nd. Year VI - Oysters were again collected by tong from around the Judges Stand and were abundant despite the high volume and long duration of freshwater experienced in Galveston Bay. Year V11 - Oysters were again collected by tong from around the Judges Stand. Year V111 - Oysters were collected by dredge from around the Judges Stand. 185 SEDEVIENTCOLLECTIONS Years I & 11 - Sediments were collected just offshore (100 m) from the oysters stations. Year III - No sediments were collected. Year rV - No sediments were collected. Year V - Sediments was also collected around the Judges Stand, with Station 1 about 50 m to the north, Station 2 was 25 m south of the stand. Station 3 was 75 m' southwest of station 2.

In Year III, the boat was launched at San Leon Marine near Eagle Point where a lift was available. In subsequent years the boat was launched at the Eagle Point Marina. SITE DESCRIPTION - The collection site was near an exposed reef midway between southeast Eagle Point and Red Fish Island at Houston Ship Channel. The reef ran from Eagle Point to Red Fish Island. This was an extensive reef with several shipwrecks. The top of the reef was exposed at low tide. OYSTER COLLECTIONS Years I & 11 - Station 1 was west-southwest of the reef between the reef and Eagle Point in 1.5 m of water. Bearing to landmarks are 85' to middle exposed reef; 180' to Railroad draw bridge. Station 2 was dredged near the exposed portion of the reef (about halfway between the marina and the ship channel dredge material islands). Station 2 landmarks were 140' to the middle of the exposed reef. Station 3 was dredged northeast of the reef at about half the distance to the island. Station 3 landmarks are 330' to the middle of exposed reef; 210' to railroad draw bridge. Year III - Year III stations were close to those previously used. Station 1 was moved approximately 0.5 miles to the north -50 m offshore of the exposed reef which borders the ship channel and east of the south end of the reef. Stations 2 and 3 were the same as those previously sampled. Year IV - In Year IV the oysters were obtained from the north side of the east/west reef extending from Eagle Point marina to the exposed reef bordering the ship channel. The location corresponds to Station 2 in previous years. At the time of sampling all commercial oystering was confined to this area and the oysters were purchased. Year V - Station 1 oysters were purchased from a lugger working on the east end of the reef. Station 3 oysters were obtained from another lugger working on the west end of the reef, approximately 200 m from the first pole at the entrance to the Eagle Point Marina. Station 2 was a combination of oysters from Stations 1 and 3. Year V1 - Station 1 oysters were collected at the high point of the reef toward the west end. Station 2 was collected at the middle of the reef near the ship 191 wrecked boat (29*29.70'N, 94*53.82W). Station 3 was dredged by a commercial lugger operating slightly north of the east end of the reef in the bend of Red Fish Island. Year VII - Station 1 oysters were collected on the northwest end of the reef approximately 200-300 m from the exposed portion of the reef. Station 2 was near the middle of the reef approximately 300 m. north of the wrecked shrimp boat. Station 3 was on the east end of the reef approximately 500 rn northeast of the shrimpboat. Oysters were numerous at the first two stations. Year VIII - Oysters were collected at the same reef segments as last year. SEDDMENT COLLEMONS Years I & Il - Sediments in Years I and II were collected north and northwest of the reef. Mud bottoms were patchy in distribution. Year III - Sediments were collected within 100 rn of each of the oyster sites. Year TV - Sediments for Year IV were collected with a box corer within 100 rn of each of the oyster collection sites described for Year III. Year V - Sediments were collected adjacent to each station. Station I was 100 M north of the east end of the exposed reef. Station 2 was 100 rn north of the center of the reef. Station 3 was 300 rn north of the oyster collection site. All the sediments were sandy-silt over black clay. Year V7 - Sediments (NIST) were collected 100 rn north of each oyster station. Years V11'& V111 - No sediments were sampled these years. SAMPLING M[ETHODS Oysters - Dredging, tonging, or hand Sediment - box core WA'fER DEPTH - intertidal to subtidal, 0.1 to 3 m POSSIBLE CONTAMINANTS - Sources of contamination included the dredging activities on the Houston ship channel, the Houston ship channel-Galveston Bay complex, and the petrochemical industry at Texas City. 192 ENVIRONMENTAL DATA Salinity Temperature Dates Sampled (0/0.)

The reef is to the northwest. In Years III & IV, the boat was launched at the Eagle Point Marina. SITE DESCRIPTIONS - Hanna Reef is a large subtidal reef that runs northwest to southeast and separates East Bay from Galveston Bay. The large exposed (only at low tide) portion in the middle served as the point. of reference for site identification. The oyster site was the submerged reef northeast of the large exposed part (bearing 055' from) and marked by two telephone pole sized pilings. Also at mid-bay there was a solitary concrete piling and a six leg wooden platform. The area was fished commercially and marked by many temporary stakes. OYSTER COLLECTIONS Year I - In Year I the oysters were obtained on site from a commercial dredger and thus no station distinction was possible. Year II - In Year II the stations were dredged from the submerged reef to the northeast of the exposed part of Hanna Reef. Station 1 was on the west side of the submerged reef, between two telephone poles. Station 2 was north of the reef. Station 3 was east of the reef. Year 111 - In Year III, oysters were purchased from a. commercial fisherman operating at Stations 1 and 2 and oysters were dredged from Station 3 at approximately the same location described above. Year IV - Oysters were purchased from commercial fishermen dredging on Hanna Reef. Year V - Oysters were tonged to the north of the exposed part of Hanna Reef on a line between the white oil platform and the six legged wood platform. Station 1 was on the west side of the reef approximately 1000 m east of the white platform. Station 2 was 150 east of Station 2 near the top of a submerged reef. Station 3 was another 200 m east toward the six legged platform. The bottom was shell and shell hash in dark brown mud. Year VI - Oysters were purchased from a commercial fisherman dredging on Hanna Reef. 199 Year VII - All three stations were dredged off of the east end of the exposed portion of Hanna reef. The first station was approximately 300 m east of the reef with Stations 2 and 3 further to the east separated by approximately 50-m. Year V111 - Oysters were dredged in the same location as Year VII. SE )IM]KNT COILECTIONS Years I, II & III - Sediments were obtained by boxcore adjacent to the oyster stations.

Take Seawall Blvd. west to 8 Mile Road, which joins Anderson Ways Road at Stewart Street. Continue on Anderson to the north almost to West Bay and turn left at Sportsman Road, proceed for -1 mile. The boat ramp is on the right between two houses. SITE DESCRIPTION - The site was a reef between Deer Island and shore, approximately 0.5 mile from the boat ramp. This large reef was exposed at low tide and was utilized by commercial and private fisherman. This was a heavily utilized reef, as was evidenced by the large number of people collecting oysters during the third year's collections. OYSTER COLLECTIONS Years 1, 11 & III - Stations were established along the edge of the reef. Station 1 was located on the eastern tip of the reef. Station 2 was in the middle of the reef and Station 3 was at the west end. Oysters were picked by hand from 0.5 m of water on both sides of the reef. Year IV - In Year IV, the prevailing winds and tides had covered the reef completely with waves of about two feet. Thus, sampling by hand on the reef margins was not possible. Oysters were obtained from a commercial dredger operating in the area of former Station 2, between Confederate Reef and South Deer Island to the north. The site was 1.7 nautical miles to the west from the green channel marker 9 at the entrance to Offatts Bayou. Years V, V1, VII, & VIII - Oysters were collected by hand at low tide from the exposed reef. Station 1 was located on the eastern tip of the reef where 50 m of reef was above water. Station 2 was in the middle of the reef to the west of Station 1. Station 3 was on the west end of the reef approximately 300 m west of Station 2. The entire reef was over hard bottom composed of shell and shell hash. SEDEVEENT COLLECTIONS Years 1, 11 & III - Sediments were patchy and were located approximately 1 mile north of the oyster stations, between Deer Island and the reef, and northeast from the island at a distance of -50 m. Sediments were collected at Lat. 29'16.1 ON and Long. 94'54.60W. 205 Year V - Sediments were collected north of the oyster stations near Deer Island. Station 1 was on the east side of the island 200 m from shore. Station 2 was on the south shore of Deer Island near a cove approximately 60 m from shore. Station 3 was on the west side of Deer Island 60 m from the shore. Sediments were silty sand over hard sand.

From Stewart Rd. Take 71st Street north to Heards Lane and then travel down Bay Drive through the apartment complex. Follow the dirt road around the turn for approximately 100 m and turn north onto private property to an open shed with a green roof. The stations were located along the shoreline north of the shed at Lat. 29116.65'N and Long. 94'50.87'W. In Year IV, the collection site was moved to the 61st bridge at the public boat ramp. SITE DESCRIPTION - This collection site was located in the middle of the south shore of Offatts Bayou. Oysters could be picked up along the shoreline but sediments had to be obtained in deeper water east of the oyster stations. Oysters were fairly common but not abundant and were attached to concrete and brick rubble or were loose on the bottom. OYSTER COLLECTIONS Year III - Year III stations were located as follows: Station 1 was located at the boat ramp and extended east to the first set of wooden pilings. Station 2 was located between the pilings and wood pier. Station 3 was located to the east of the wood fishing pier. Years IV, V & VI - In Year IV, the Offatts Bayou site was moved to the east end of the bayou to correspond to the location from which sediments were sampled in Year III. The new GBOB stations were located on the 61st Street causeway at the bridge which crosses.the bayou. Station 1 was on the bay side of the bridge, extending from the bridge to the public launching ramp. Station 2 began under the bridge (on the south side) and extended into the enclosed basin part of the bayou. Station 3 was inside the small basin, extending south from the bridge. Years VII & VIII - Oyster collection stations were located at the same sites described above. SEDDIENT COLLEMONS Years III - Sediment was collected at the east end of Offatts Bayou near the shoreline. This was the only place in the bayou where mud was found. All other sites had sandy bottoms. Years IV, V, V1, VII, & V1-11 - No sediments were sampled during these years. 211 SAMPLING METHODS Oysters - hand Sediment - box core WATER DEPTH - 0 to 0.5 m. POSSIBLE CONTAMINANTS - No obvious point sources of contamination were seen; however, this bay was surrounded by housing and residential development and had a long-term history of pollution.

The ramp is on the right just after crossing into Louisiana. The site is north of the ramp at Blue Buck Point about a 10 minute run by boat. In some years, there were numerous gill nets in the area. SITE DESCRI]PTION - The site was at or adjacent to Blue Buck Point in the lower part of Sabine Lake. Oysters have been collected by hand along the shoreline and by tonging in deeper water offshore from the point. Oysters occured in clumps on the shell and mud bottom and were not overly abundant. OYSTER COLLECTIONS Year I - Oysters were collected by dredge and by hand the first year. Station 1 was dredged 300 m north of Blue Buck Point at a bearing of 360' from the point, 110' from the middle of the ICWW bridge, and 3401 from the tall radio tower to the south. Station 2 was collected by hand just offshore approximately 80-m south of the point. Station 3 was 350 m south of Station 2 about 10 m offshore. Year Il - Collection sites were along the shoreline . Station 1 was collected along the western margin of the lake at Blue Buck Point approximately 1 to 10 m offshore. Station 1 was a composite of Stations 2 and 3 since the collectors were unable to find oysters at last years station. Station 2 was just south of the point and Station 3 was approximately 200 m farther south. Year III - Oysters were tonged 200 m offshore with Station 1 off the western edge of Blue Buck Point. Station 2 was south of the point and Station 3 was 200 m farther south. Oysters were scatter clumps in the sandy mud bottom. Year I-V - Year IV Stations were located slightly farther offshore than previously sampled. Station 1 was 250 m south of the duck blind at Blue Buck Point. Station 2 was 400 m southeast of the duck blind and 250 m south of Station 1, located at a pole and approximately due west of several oil tanks on the shore. Station 3 was 250 m south of Station 2. Numerous oysters were dead or near death, the reef appeared to have had a partial die-off, and appeared to be recovering. 223 Years V & VI - Oysters were located along a narrow reef with a few live oysters attached to dead clumps. Station 1 was 300 m west of the point. Station 2 was 100 m south of the point. Station 3 was 150 m south of station 2. Year VII - Oysters were collections were at the same stations as the previous two years. Oysters were very sparse with many recently dead. Year VIII - Oysters were collected at the same station as the previous three years. SEDIMIM COLLEMONS Years 1, 11 & III - Each year the sediments were collected offshore in subtidal waters adjacent to the respective oyster sample stations. Year VI - Sediment sites for NIST sediments were collocated with each oyster station. Years IV, V, VII, & VIII - No sediments were sampled during these years.

SNE NUMBER - 60 DESIGNATOR - CLLC SITE - CALCASIEU LAKE, LAKE CHARLES LA NOM[INAL SUIE CENTER - 30003.42'N 93018.42V LOCATED ON NOS CELART # - 11347 SITE ACCESS - Access to the site is via LA Highway 384 to Deatonville and a boat launch at the Cajun Cove Marina. The channel going out from the launch is very shallow at low tide. From the launch proceed northwest along the shoreline for -700 m to a long pier at the Reef Restaurant. In Year V the site was moved, so after launching proceed on a bearing of 800 from the ramp to the shell island. The GIWW bridge is due west of the site. Since the site was moved it is much easier to launch the boat at the Ellender Bridge and go up the GIWW, to the north end of Calcasieu Lake. SITE DESCREPTION - This collection site, established in Year III, was located in the north end of Calcasieu Lake at East Pass (30*03.50'N and 93,17.50W). Oysters were scattered on a submerged (0.75 to 1 m deep) muddy reef, with individual clumps of 3-10 oysters. Oysters were thin-shelled and broke easily when separated. In Year V the site was moved 1 mile to the west to an oyster shell reef and nearby Spartina alterniflora marshes. OYSTER COLLECT[ONS Years III & X - Year III oyster Station 1 was located 30 m. south of the end of the Reef Restaurant Pier. Landmarks to locate this site were 2700 to the twin towers of the Ellender Lift Bridge and 1340 to the Cajun Cove Marina ramp. Station 2 was 75 m southeast of Station 1 approximately 30 m off of the private piers. Station 3 was another 75 m southeast, 30 m off of the last private pier. Year V - The collection site was relocated about a mile- west due to the lack of live oysters at last year's site. The new site is a oyster shell island with marsh grass nearby. Oysters can be collected by hand during low tide. Station 1 was located on the south, end of the shell reef just to the north of the Spartina island. Station 2 was 75 m to the north and Station 3 was 100 m west of Station 2. Years VI & VII - Oysters were collected at the same stations described in Year V. There is a new orange metal post marker on the north end of the reef. An oyster die off has occurred since last year, only small oysters were present. Year VIII - Oysters were collected at the same stations described in Year V. Oysters were more abundant and larger than the previous two years. 235 SEDIMENT COLLECTIONS Year III - Sediments were a light gray-brown, fine-grained clayey layer over a dark brown clay. Collection sites were collocated with each oyster site. Years IV & V - No sediments were sampled during these years. Years VI - NIST sediments were collected 50 m from the oyster stations in 1.5 m of water. Years 1-V, V, VII, & VIII - No sediments were sampled during these years. SAMPLING MEvMODS Oysters - tongs and hand Sediment - box core WATER DEPTH - intertidal, 0.2 to 0.5 m POSSIBLE CONTAMINANTS - Potential local contamination was from private piers, septic tanks, oil production, and boat traffic in the ICWW. However, since the site was located at the mouth of the Calcasieu River, there was a much greater potential for contamination from upstream discharges particularly fiom the Lake Charles metropolitan area.

HARBOR BAYOU LA NOAHNAL SYM CENTER - 29*37.75'N 92045.75V LOCATED ON NOS CHART # - 11345,11344 SITE ACCESS - Access to the site is by boat launched at the Gran Chenier Boat Ramp on Highway 82, west of North Island canal. Proceed by boat south along a man-made channel to the mouth of Joseph Harbor Bayou. Run time to the site is approximately 0.5 hrs. SITE DESCRIPTION - The collection sites were located on both sides of the channel; 300' from the Gulf along the grassy margins of the bayou east of Miller Lake. Oysters were taken from intertidal waters from a mud and shell bottom. Low tide was the optimum collection time. OYSTER COLLECTIONS Years 1, Iff, IV & V - Year I stations were established as follows: Station 1 oysters and sediments were collected from the east bank of the bayou 200 m north of the entrance to the Gulf with a bearing of 180' to the abandoned wooden structure. There were very few oysters at Station 1. Station 2 was collected from an exposed reef on the west bank of the bayou on the second bend approximately 0.5 km upstream from the Gulf. Bearings to locate the site were 130' to abandoned structure; 320' to deer stand. Station 3 was collected from an exposed reef 60 m north of Station 2. Year Il - In Year II, the mouth of Joseph Bayou had been dredged a few days prior to collecting. This reduced the number of oysters present but the station locations were the same. Year V1, VII, & VIII - Stations were located in the same areas as previous years. Oysters were more abundant and larger. SEDEMEENTCOLLECTIONS Years I, II & III - Sediment stations were collocated with each oyster collection site. Years IV, V, VI, V11, & VIII - No sediments were sampled during these years. SAMPLING METHOD Oysters - hand Sediment- hand 241 WATER DEPTH - intertidal, 0.2 m. POSSIBLE CONTAMINANTS - Dredging was the only source of contamination observed at the site.

Shoaling is very steep and treacherous through Southwest Pass, especially on the west side of the channel opposite Marsh Island. Keep in the channel until seaward of channel marker 3 or well into Vermilion Bay. SITE. DESCRIPTION - The site was located adjacent to the channel outside of lighthouse point in lease 25918. Oysters are located at the mouth of Southwest Pass. Oyster reefs and private leases are ubiquitous in the area, but oysters are not necessarily in the same place each year. There were no significant geographic differences recognized in the oyster stations for this site. OYSTER COLLECTIONS Year I - Oysters were collected due east of channel marker 3 in Year 1. Years II & III - In Year II, only dead shells were found at the Year I site, so in Years II and III, oysters were purchased from a commercial dredging boat operating on private leases on the east side of channel marker 3. Therefore, no distinct stations were recognized. Year I-V - The site was the same as in Year II and III. Oysters were purchased from a commercial dredger operating to the east of the channel entrance; east of channel marker 3 and south of channel marker 5. No distinct stations were delineated. Year V - Oysters were purchased from a commercial lugger working 200 m east of channel marker 3. Stations were not distinguished. Year VI - Oysters were purchased from a commercial lugger working 200 m west of channel marker 3 (29'34.89'N, 92'03.14'W). Stations were not separated. Year V11 - Oysters were dredged from the edge of a private lease approximately 200 to 300 m east of channel marker 3. Large oysters were not abundant but many small oysters were present. All three stations were located along a north-south line covering 150 m. Year VIII - Oysters were collected by dredge at the same locations sampled in Year VII. 247 IDMENTCOLTEMONS Years I, II, & III - The mud was approximately 100 m from shore. Sediments at all three stations were 1-2 cm of fine-grained loose brown silt over gray clay. For all years, fine-grain sediments were located northwest from channel marker 3, less than 100 m from shore, and -0.5 mile from the site of the oyster collections. Station 1 was 60 m offshore on a 1900 bearing from the tank on shore; 185* to pair of rusty tanks; 870 to channel marker green 3. Station 2 was 50 m from shore on a line from channel marker 1 to the tanks. Landmarks and bearing were 286' to 4 tanks; 190' to oyster sampling site. Station 3 was on a line from channel marker 3 to the tanks -100 m from the shore. Years I-V, V, VI, VII, & VIII - No sediments were sampled during these years. SAMPLINGMETHOD Oysters - dredge Sediment - box core WATER DEPTH - subtidal, 1.5 to 2 m POSSIBLE CONTAMINANTS - No point sources were identified other than oil wells in Vermilion Bay.

No oysters were sampled/available; sediments were sampled. - This site was located on the southeast side of Marsh Island. With the help of the Louisiana Fish and Wildlife Department, we found the very old shell rubble reefs but no living oysters of any size. Oystermen of the area reported no living oysters were known to be in the entire area of East Cote Blanche. The site was deleted from study as no alternate site in the geographic area was available.

The only launch ramp is at Dularge Sporting Goods. Proceed south on Bayou Dularge, across. Caillou Lake into the open Gulf and then west along the beach front to Oyster Bayou. A more circuitous route is possible through Lake Merchant, winding through the bayou to Four Leagues Bay, then south to Oyster Bayou. However, the bayou is shallow and should not be attempted with boat draft of 2 feet or more or at low tide. SITE DESCRIPTION - The sampling stations were located throughout the length of the Oyster Bayou which joined Four League Bay with the Gulf of Mexico on the south. Oysters were extremely abundant and were obtained either with a dredge or collected by hand along the shore. However, the entire area was leased by Mr. Wilson Voisin. Oysters could be obtained only with his permission or purchased by the sack from his boats when they were oystering. OYSTER COLLECTIONS - In all years when oysters were collected by hand, dredge or purchased, the sampling stations were: Station 1 was at the mouth of the bayou, along the west bank; Station 2 on a reef paralleling the west side of the bayou -300 m north of the shrimp drying facility; and Station 3 was a large reef in Four League Bay at the north end of Oyster Bayou. Landmarks included the channel entrance marker, an abandoned shrimp drying facility, and the ends of the bayou where it entered the bay and Gulf. Year I - Oysters were collected by hand. Year If- Oyster were purchased from a commercial oyster dredge. Year Iff - Oyster were collected by dredge. Year IV - The stations. sampled in Year IV were the same as were sampled for all previous years. Oysters were dredged at Station 1 and collected by hand near the shore at Stations 2 and 3. Year V - Oysters were purchased from Mr. Wilson Voisin. They were dredged by a lugger working on the north end of the bayou between Station 1 and 2. No stations were designated. A recent freeze had killed all of the oysters along the shoreline and to a depth of 1 m due to extreme low tides. Year VI - Oysters were collected this year since the area was closed due to excessive freshwater. Station I was dredged at the north end of Oyster Bayou on the west side of the channel. Station 2 was collected by hand &om 255 a reef on the west side of the channel across from the three buildings. Station 3 was also on the west bank approximately 0.5 mi north of the mouth of Oyster Bayou and 300 m south of the shrimp drying facility ruins. Year VII - Oyster collection Stations 1 and 2 were located at the same sites as last year. Station 3 was just to the south of station 2. Oysters were abundant this year. Year VIII - Oysters were collected at the same locations sampled in Year VIL SEDDIENTCOLLEMONS Years I, II, & Iff - Sediment Station 1 was located in a small cove on the west bank at the mouth of Oyster Bayou. Station 2 was located on the east side shoreline- 0.5 miles north of Station 1 and was 300 m south of the shrimp dryer at a fringe marsh along the east shore. Station 3 was located north of Station 2 on the east shore 0.5 miles south of an abandoned shrimp drying plant. Station 3 was at the southernmost piling of the old dock at the three wooden buildings with rusty tin roofs. Sediments were variable but were generally soft gray-black mud. Years.1-V, V, VI, VII, & VIII - No sediments were sampled during these years.

SITE NUMBER - 25 DESIGNATOR - CLCL SITE - CAILLOU LAKE, CAILLOU LAKE LA NONONAL SrIE'CENTER - 29015.25N 90055.80W LOCATED ON NOS CHART # - 11356 SITE ACCESS - A boat launch is at Bayou Dularge Sporting Goods at the end of LA Highway 315. Take Bayou Dularge southwest to the channel separating Lake Caillou and Lake Merchant and turn south toward the Fish and Wildlife Camp on the island'. Run time to the site is 0.5 hrs. SITE DESCRIPTION - The site was located in Lake Caillou on a submerged reef running from channel marker 16 to Fish and Wildlife Camp. The reef was usually closed to oystering, and it was necessary to notify the F&WL camp prior to sampling. Dredging or tonging was required. OYSTER COLLECTIONS Year I - Oysters were patchy on the bottom running on a line from the channel marker to the camp, and could only be located by feeling the bottom with a bamboo pole. No station distinctions were made at this open water subtidal site because of the sparsity of oysters. Year II - Oysters were dredged from the same location as the first year. Year III - Year III oysters were abundant and were easily dredged. Year 1-V - In Year IV, the oysters were dredged from approximately the same location as was sampled in all previous years. The dredging was done between channel markers 14 and 16, in front of the F&WL camp, and about 150 m east. Year V - Oysters were dredged from the same general locations as previously sampled. Station 1 oysters were collected between channel marker 16 and the F&WL camp. Stations 2 and 3 were collected 200 m south of channel marker 16 where the reef runs north-south. The bottom was soft mud and scattered shell. Year VI - All three oyster stations were dredged from the same area as previously sampled (29'15.42'N, 90055.91'W). Calliou Lake was opened two weeks for commercial oysters just prior to our sampling. Because of this oysters were not abundant. Years VII & VIII - Oysters were collected in the same general locality. Several tows of the dredge were made approximately 50 to 100 m east of channel marker 14 on line to the F&WL camp. Oysters were abundant but distinct stations were not recognized due to the limited size of the reef. 2a SEDDMENT COLLECTIONS Years 1, 11, & HI - Sediments were located to the north of the oyster site, along the shoreline which separated Bayou DuLarge from Lake Caillou. Sediment Station 1 (in all years) was located at the base of channel marker 18. Station 2 was located at the mouth of a small cove 300 m to the east. Station 3 was located -100 m from the shore at a large cove which was due north of the FV%rL Camp. Sediments were variable, Stations 1 and 2 were dark gray silty mud with a thin brown top layer. Station 3 was stiff gray clay with a coarse sandy mud layer on top. Years IV, V, VI, VIT & VIII - No sediments were sampled during these years. SAMIPLINGMETHOD Oysters - dredge Sediment - box core WATER DEPTII - 2 m POSSI]BLE CONTAMINANTS - Possible sources of contamination in the vicinity included numerous camp houses without sewer systems along Bayou DuLarge.

Turn right (east) into Lapeyrouse Canal and proceed to Bayou Terrebonne, turn south and proceed to the third cut into Bay la Fleur. Run time to the site is approximately 0.5 hrs. SITE DESCRIPTION - The three stations were located along Bayou Terrebonne. In Year 1, Stations 1 and 2 were on the west side of the channel and Station 3 was on the east side. In Year II and following years, Station 1 and 3 were reversed and Station 2 remained unchanged. OYSTER COLLECTIONS Year I - Station 1 was off Bayou Terrebonne in a small bay on the west side of the bayou about 0.5 miles north of Lake Barre. Landmarks and bearing were: 265' to LUMCON tower; 163' to green channel marker 3, and 106' to the Montegert water tower. Station 2 was located upstream at the mouth of bayou in grass near an old fishing camp on Bayou Terrebonne at the first cut to the west into Bayou Lucien. Bearings were 258' to LUMCON; 116' to the green channel marker 1. Oysters and sediments were taken near the remains of a galvanized corrugated iron shed and wood dock in intertidal waters on the northwest shore. Station 3 was farther north on Bayou Terrebonne at the next cut (Lake Barre pass) to the east which was the first cut to the east north of Seabreeze Pass. This cut connected to Bay la Fleur on the east side of Terrebonne Bayou. Oysters were from an intertidal reef on southwest shore and sediments from subtidal waters. The reef was exposed at low tide. Oysters were abundant at all three sample areas. Years 11, 111, IV, V & VI - Stations 1 and 3 were reversed these years. Years VII & VIII - Stations were located in the same sites sampled the previous five years. Station 1 on the north, Station 2 in the middle and Station 3 was on the south end of the bayou. SEDDIENT COLLECTIONS Years 1, 11, & III - Sediment collections were collocated with each of the oyster stations. Years I-V, V, V1, V11, & VIII - No sediments were sampled during these years. 267 SAMPLINGMETHOD Oysters - hand Sediment - hand WATER DEPTH - intertidal, 0.1 - 0.5 m POSSIBLE CONTAMINANTS - Contamination factors included marine traffic and the fish camp ruins at Station 2.

SITE NUMBER - 27 DESIGNATOR - TBLF SITE - LAKE FELICITY, TERREBONNE BAY LA NOARNAL SITE CENTER - 29015.80'N 90024.40W LOCATED ON NOS CHART # - 11357 SITE ACCESS - The launch/departure point is Coco Marina at Cocodrie or the boat ramp at LUMCON, and the run time is -1.5 hours to the site by boat. A deep draft outboard must enter and cross Terrebonne Bay to Lake Felicity. A shallow draft outboard can shortcut up the bayou to enter and cross Lake Barre (see directions for TBLB). The site is located at an abandoned and dilapidated fish camp on the southeast side of Lake Felicity, near Bayou Point Au Chien. Landforms in the area bear little resemblance to any maps or charts of the area and navigation to the site by reference to shoreline features as depicted in charts is nearly impossible. SITE DESCREPTION - The oysters were intertidal and interspersed in the grass beds on the small islands surrounding the fish camp. The only landmark in locating the oyster stations was the fish camp structure, which burned down in Year III. OYSTER COLLECTIONS Years I, II, &III - Station 1 was located at southeast corner of bay, south of channel marker 5 for Felicity Bayou at an abandoned fish camp. Station 1 was located on the island (grass covered flat) at the abandoned fish camp. Station 2 was a subtidal Spartina bed across the channel on the island bearing 162' from the fish camp. Station 3 was a subtidal grass bed west of the fish camp on the island bearing 240' from the fish camp. Years IV & V - Prior to the Year IV sampling, the fish camp had burned to the ground. In Year IV, Stations 1 and 3 were in the same locations but Station 2 was moved due to the lack of oysters. The new Station 2 was located approximately 200 m northwest (320 bearing from Station 1) of the dock at the fish camp. Station 2 is a small reef at the edge of the Spartina marsh. Year W, V11, & VIII - Oysters were collected at the same locations as sampled last five years. SEMIEW COLLEC`ITONS Years 1, If, & III - Sediments are silty mud and collocated with the oysters. Sediments were taken from the subtidal waters adjacent to each of the oyster stations. Years IV, V, VT VIT & VIII - No sediments were sampled during these years. 273 SAMPLINGMETHODS, Oysters - hand Sediment - hand WATER DEPTH - intertidal, 0 to 0.5 rn POSSIBLE CONTAMINANTS - There were no obvious sources of contamination in the vicinity except for the very large producing oil and gas field in Terrebonne Bay between Lake Barre and Lake Felicity.

DENIS, BARATARIA BAY LA NOMONAL SrM CENTER - 29024.18'N 89059.75V LOCATED ON NOS CHART # - 11358 SITE ACCESS - The site is accessed by boat, launching at the Happy Jack Marina in Point Sulfur or the Cheramines Marina in Grand Isle. From Grand Isle proceed north up the Barataria Waterway to green channel marker 31. Islands and landforms have changed since the chart was published, and the land forms provide little reference for determining position. Run time to the site is approximately 1 hr. SITE DESCRIPTION - This site was located in Bayou Cholas on the west side of Barataria Bay and the Barataria Waterway. Oysters have been collected in the bay area and along the shoreline of the small island on the north side of the bay. OYSTER COLLECTIONS Years I & Il - Oysters in Years I and II were taken from intertidal mud and sand bottom on the west side of island west of green channel marker 31. The oysters found were very. old and few in numbers. Year I oysters were purchased from a commercial lugger working on the reefs in the area. Station 1 was on the south part of the island, at a bearing of 360 0 to channel marker 9. Station 2 was 120 m north of Station 1. Landmark bearings were 121' to channel marker 9; 20' to channel marker 11. Station 3 was 100 m north of Station 2. Bearing were 65 0 to pipeline platform and 2851 to channel marker 9. Year III - Year III stations were on a submerged reef west of Barataria Waterway between channel marker 30 and 33, near several small islands to the west in Bayou Cholas. Station 1 was on a bearing of 30' to green marker 13 and 105' to marker 9. Station 2 was 50 m to the south, and Station 3 was another 50 m south. Year IV - Due to the lack of oysters at the stations sampled in Year III, the sample location was moved approximately 500 m to the east. Year IV stations were located on the island directly west of channel marker 33. Station 1 was on the east end of the island (nearest the channel) and extended along the south facing shoreline for 50 m. Station 2 was in the middle part of the island and was 50 m due west of Station 1. Station 3 was on the west end of the island next to Station 2. Year V - Stations collected this year were those described in Year IV. Oysters were scarce. There were numerous dead oysters and fish due to the recent hard freeze. 279 Year VI - There were no oysters on the island this year so the site was moved back to the submerged reef. Stations sampled in Year III were resampled this year. Year VII - There were no live oysters found in this part of the bay. Year VIII - Oysters were present again this year, but were scarce and small. Stations sampled in Year III were resampled this year. SEDIMENT COLLECTIONS Years I & Il - Sediments were taken from subtidal areas west of channel marker 26. Year 111 - Sediments were taken adjacent to the reef 30-40 m east of each station. Year 1"V - Sediments were collected 100 to 150 m south of each oyster station in 1 to 1.5 m of water. Years V, V1, VII, & VIII- Sediments were not sampled during these years. SAMPLINGMETHOD Oysters - commercial dredge, tongs, and hand Sediments - box core WATER DEPTH - intertidal or subtidal, 0.3 to 3 meters POSSIBLE CONTAMINANTS - Contamination factors included marine traffic, dredging, and a compressor station.

The site was only 10 minutes &om Grand Isle. Oysters and sediments during Years I, II and III were collected from intertidal waters inside the Fish and Wildlife boat.basin. Oysters were found scattered on the mud and sand bottom. There were very few oysters during Year II. There was a reported die-off after the first year's collection. OYSTER COLLECTIONS Years I, II, III, IV, V, VI, VII, & VIII - Station locations for oyster collections were: Station 1 - located at the dock; Station 2 - 50 m to the north; Station 3 - 70 m north of Station 2. Station locations were the same for all eight years. SEDIM19*-U COLLECTIONS Years 1, 11, & III - Sediments were collected along the channel adjacent to each of the oyster stations. Years IV, V, VT V11, & VII1'- Sediments were not sampled during these years. SAMPLINGMETHOD Oysters - hand Sediment - hand WATER DEPTH - intertidal, 0 to 0.5 meters POSSIBLE CONTAMINANTS - Possible contamination would be from Fish and Wildlife bottom-fouling paint and possibly from pesticides. 285 ENVIRONADENTAL DATA Salinity Temperature Dates Sampled (10/00) (OC) YEAR 1 22.0 24.0 27 March 1986 YEAR II - 22.0 12 February 1987 YEAR 111 23.0 11.0 28 January 1988 YEAR IV 29.0 21.0 6 January 1989 YEAR V 30.0 18.0 6 January 1990 YEAR VI 23.0 16.0 8 January 1991 YEAR VII 27.0 18.0 8 January 1992 YEAR VIII 20.0 19.0 5 January 1993 286 16 3#4 s4i 6"', Z;, Tl Tt .................

By boat proceed north on Barataria Waterway and turn left into Bayou Rigolettes. Follow Bayou Rigolettes south of Harvey Cutoff and then south to Turtle Bay. In Turtle Bay proceed southeast for approximately 1.2 miles past the mouth of Long Bay to the mouth of Bayou St. Denis past several small islands en route. SITE DESCRIPTION - The site, established in Year III, was located on the south side of the entrance to Bayou St. Denis from Little Lake at a row of red and white poles which parallel the shoreline to the south. Oysters were not abundant; therefore distinct stations were not established. Oysters were dredged from a black muddy bottom which contained numerous dead shells. Landmarks to locate the site were: 110* to a small treed island and 30' to a green camp house and silver storage tank. OY91ER COLLECTIONS Year III - Station 1 was at the north end of the island 50 m from shore. Station 2 was 20 m offshore, opposite the oyster dredge site. Station 3 was at the south end of the dredge site in a small cove 20 m from shore. Years IV, V, VI, V11, & VIII - This site was not sampled during these years. SEDDIENT COLLECTIONS Year III - Sediments were taken along the shoreline to the south. Sediments were black fine silty mud with detrital matter and an obvious H2S odor. Years IV, V, VT V11, & VIII - Sediments were not sampled during these years.

SITE NUMBER - 65 DESIGNATOR - MRTP SITE - MISSISSIPPI RIVER, TIGER PASS LA NOMINAL SITE CENTER - 29008.69'N 89025.67V LOCATED ON NOS CHART # - 11361 SITE ACCESS - Access to the site is by boat. From the boat launch at the Venice Marina proceed down Tiger Pass; this takes 0.5 to 1 hour depending on weather conditions. It is best not to go to the site in foggy weather. The mouth of Tiger Pass is bordered by a jetty on both sides; proceed past the jetty on the north side to channel marker 7 then turn north and go back to the shoreline. The site is directly north of the jetty and channel marker 9. SITE DESCRIPTION - This site, established in Year III, was located on the west side of the Mississippi River delta near the mouth of Tiger Pass. The site was on the southwest shoreline of a small smooth cordgrass island. The site was located near a telephone pole at the edge of the marsh. OYSTER COLLECTIONS Year III - Individual stations were contiguous along the shoreline. Station 1 was along the shoreline just north of where the Tenneco pipeline canal ran into the bay on the east and southeast from the pole at Station 2. Station 2 was the next -100 m of shoreline to the north across from the telephone pole with two bolts. The pole was approximately 20 m from the shoreline. Station 3 was northwest from the pole UP to where the canal forms the northwest boundary of the marsh island. Oysters at all three sites were found lying in the edge of the marsh in the smooth cordgrass marsh. Year rV - The same three stations were again sampled, except that Station 3 was combined with Station 2 because of the scarcity of oysters in the Station 3 location. Station 2 oysters were larger and more abundant than in the initial sampling in Year III. Year V - There were very few oysters present this year. Due to the scarcity of oysters, Stations 1 and 2 were not distinguished. All the oysters in the area were collected and split into two groups. Station 3 was in the same location as previous years. The number of oysters has decreased each year and it may be necessary to move this site. Year V1 - The same site was collected this year. Oysters were almost depleted from this area and only a partial set of oyster samples were collected this year. Additional sites in the immediate vicinity were examined but no oysters were present. There was no oyster reproduction occurring at this site and there were no oysters remaining to be collected, therefore a new site farther to the north should be established. 297 Year VII - The same site was collected this year. Oysters were not abundant thus distinct sites were not recognized. Year VIII - The same stations sampled in Year V were resampled this year; however, dinstinct stations were not recognized since oysters were not abundant. SEDDIENTCOLLECTIONS Year III - Sediments were collected offshore of the oyster stations. Sediments were composed of fine silty muds taken 20-50 m offshore from the oyster stations. Station 1 was at the southeast point of the marsh island, Station 2 was 20 m offshore from the oysters. Station 3 was northwest across the channel from the oysters. Years IV, V, 'V7, VII, & VIII - Sediments were not sampled during these years. SAMPLINGMETHOD Oysters - hand Sediments - box core WATER DEPTH - intertidal, 0 to 0.1 meters POSSIBLE CONTAMINANTS - No known sources of contamination were visible.

From the boat basin, head upstream to the main fork of the Mississippi River and proceed downstream to Head of Passes. At this point, take the east fork holding to the south shore to avoid the large sandbar at the entrance to Pass a Loutre. Proceed east to the first cut to the south and proceed to the Louisiana Fish and Wildlife Headquarters which is located south of the entrance to Johnson Pass. The Louisiana Fish and Wildlife personnel provided guidance to the site the first year. Proceed back upstream to Loomis Pass, turn to the southeast into the pass and proceed downstream entering Cognevich Pass and on into the Gulf of Mexico. At this point, turn north to the mouth of Redfish Bay. No attempt should be made to travel to this site except in calm weather. SITE DESCRIPTION - The site is located at the extreme southeast edge of Redfish Bay just north of the last small island. Prominent landmarks are the Port Eads Lighthouse (240') at South Pass and the Exxon platform with green tanks (350'). OYSTER COLLECTIONS Year III - No distinct oyster stations were established at this site. Oysters were located by poling and occur in scattered areas of large clumps of old large oysters. This was an old reef which has silted over with fine sediment. Oysters were collected with tongs and are difficult to break loose from the reef. Year rV - Oysters were collected by dredge in the same area that was tonged in Year III. Sampling was difficult because of windy conditions and the overall sparsity of live oyster beds. Dredging yielded barely enough for two replicates. The site was located about. 200 m east of the seawardmost pole marking the entrance to Johnson Pass, and on a line to the small barrier island. The only way to find the isolated scatterings of oysters in the soft mud was to randomly dredge or feel the bottom with a bamboo pole. This did not distinguish live and dead reefs. Oysters could not be hand picked from the marsh plants on the nearby islands because the mud was far too soft to walk on and the water was too shallow to approach by boat. Year V - Oysters were again dredged from along the north side of the last Phragmites island on line with Port Eads lighthouse and the green oil tanks (29'04.30'N, 89'04.60'W). Oysters were found primarily on roots and old crabs pots and were very scarce. It required 2 hours of 303 dredging to obtain enough oysters for three replicates. The substrate was a black anoxic mud. Year VI - This site was not sampled this year. Year WI - The site was moved slightly to the north and west of the Year V site. Oysters were dredged from a linear submerged reef west of the small Phragmites island. The site was approximately 500 m due south of the green oil tanks located near the north end of Redfish Bay. The reef was very narrow and difficult to locate. Year VIII - Oysters were dredged from the south end of the linear reef described in Year VII. Distinct stations were not recognized since extensive dredging was required to obtain an adequate sample. SEDIMENT COLLECTIONS Year III - Three sediment stations were established on the reef -100 m apart. Fine grained silty sediment were mixed with shell. Years X, V, VT VII, & VIIl - Sediments were not sampled during these years. SAMPLING ME'I'HODS Oyster - tongs or dredge Sediment - box core WATER DEPTH - subtidal, 1 to 5 meters POSSIBLE CONTAMINANTS - The only point sources were the nearby oil productions facilities in the upper part of Redfish Bay.

Proceed from the marina southeast down the Back Levee Canal to Lower Grand Bayou, then east along the bayou to Battle Ground Bay. In Battle Ground Bay go generally east paralleling the shore to Tripple Pass. Then go northeast and northwest to Pintail Point in Bay Gardene. At Pintail Point proceed east-northeast to Bayou Lost to the Louisiana Fish and Wildlife Camp. The site is along the south shore of the western end of Bayou Lost, west of the Fish and Wildlife Camp. Approximate run time to the site is 0.75 hours. SITE DESCRIPTION - This site was located on small unnamed islands between Bayou Lost and Lonesome Island. Oysters were abundant. No visible contamination factors were observed. OYSTER COLLECTIONS Year I - Oysters were collected by dredge off the western tip of the island. Landmarks used to located the position are: 68' -to the Fish and Wildlife camp, 129' to white grain elevators, and 293' to the oil terminal. Years II & 11 - In all years, Station 1 was collected on the westernmost tip of the island on the south side of Bayou Lost near Pintail Point in Bay Gardene. Station 2 was 100 m to the east of Station 1. Station 3 was 100 m to the east of Station 2. Years IV, V, V1, VIT & VIII - The stations sampled were the same as in previous years, along the east end of the island at the Fish & Wildlife camp on the south shore of Bayou Lost.

Sr1E NUMBER - 31 DESIGNATOR-BSSI SITE - SABLE ISLAND, BRETON SOUND LA NOMINAL SITE CENTER - 29024.11'N 89029.10W LOCATED ON NOS CHART # - 11364 SITE ACCESS - During the first two years, access to the site was by boat which was launched at Point a La Hache Marina. Proceed southeast on Back Levee Canal to Fucich Bayou. Fucich Bayou enters California Bay and channel markers are followed to California Point. Avoid the shoals at California Point by staying near the platform structure off the point where the telephone lines appear to end. Turn south from California point and cross through the oil field to Sable Island. Travel time by boat is 1 to 1.5 hours, and the open water crossing at California Bay and south to Sable Island requires a calm day and/or a larger protected boat. In Years III-V of the study, the boat was launched at the Venice Marina. There are several way to reach the site but the easiest is to go up the Mississippi River to the Ostrica Canal Locks and then out the private channel across Quarantine Bay to Sable Island. Run time to the. site is still about an hour. In Year VI a new launch site was used at Delta Marine in Empire. It is necessary to go through the Empire Lock then down river to the Ostrica Lock, but the run time is much shorter than coming up, river. SITE DESCRIPTION The site surrounded Sable Island. Oyster reefs were ubiquitous around the island, but live oysters were found by trial and error. The best oyster beds were on the southwest end of the island. OYSTER COLLECTIONS Years I & Il - Oysters were found by commercial oystermen on the north side of the island in Year I (29'24.70N. 89'28.70'W)(with limited success), and were more abundant on the south side in Year II (29*24.20'N, 89*28.80'W) (again with a commercial dredger collecting the samples). Landmarks to help locate the area were: Station 1 - 245' to well nearest north shore; 310' to tanks nearest large platform. Station 2 - 20' to the nearest well on the north shore; 257' to platform with 4 pipes and 3 tanks. Station 3 - 262' to platform with 3 pipes and 3 tanks; 344' to nearest large platform on the north side of the island. Year III - In Year III, oysters were hand collected at Station 1 on the northwest shore of Sable Island (29'24.21'N, 89'29.10'W), oysters were not abundant. Oysters at Stations 2 and 3 were purchased from commercial fishermen who were operating just offshore. Year 1-V - The oysters were collected by dredge in the area between the larger part of Sable Island and the smaller mostly shell island to the north (29023.94'N, 89029.09'W). Oysters for all three sites were taken from a marked leased area about 200 m west of the well jacket with a red beacon light. Oysters were plentiful on a mud bottom in 1 m of water. 315 Year V - Oysters were dredged on the northwest side of the island along the edge of the reef approximately 50 m from the island. All stations were obtained along a 500 m area (29'24.32'N, 89*29.05'W). Oysters were not plentiful. Year V1 - All three stations were located off of the southwest end of the island (29024.20'N, 89029.04'W). Station 1 was located on the south end and west side of the island. Station 2 was approximately 100 m farther southwest. Station 3 was another 100 m to the southwest of Station 2. Oysters were sparse at Stations 1 and 2 and abundant at Station 3. Year VII - Oysters were collected near the same stations described for Year VI, but the stations were shifted slightly to the southwest. Oysters were moderately abundant with numerous mussels attached. Year VIII - Oysters were collected at the station described for Year VII. Mussels were very numerous,, covering most of the oyster shell. SEDIMENT COLLECTIONS Years 1, 11, & III - Sediments were available nearshore on the south side. In all years' sediments were collected at three stations -50 m apart on the south side of the island. Sediments were gray-brown silt over dark black mud. Years X, V, VI, VII, & VIII - Sediments were not sampled during these years.

SrIE NUMBER - 63 DESIGNATOR - LPGO SITE - GULF OUTLET, LAKE PONTCHARTRAIN LA NONUNAL SITE CENTER - 30002.,M'N 90002.57V LOCATED ON NOS CMMT 11369 SITE, ACCESS - A boat is launched at the ramps located under Shoreline Drive Bn'idge. The site is located just to the north of the ramps in the south edge of Lake Pontchartrain. Travel time to the site is less than 5 minutes. This site cannot be sampled when there is a strong north wind due to high waves. SITE DESCREPTION - An attempt was made in Year III to establish a site at the Gulf Outlet on the south shore of Lake Pontchartrain. Although the site was recommended as being most likely to support oysters, no oysters were present; therefore, no stations were established nor was sediment collected. Based on new information, a sampling site was established in Year VI near the Gulf Outlet on the south side of Lake Pontchartrain. The site was located approximately I km north of the bridge adjacent to the New Orleans Lakefront Airport. Oysters occured at this site due to a salt water wedge that entered through the outlet. The high salinity water allowed the oysters to exist on the bottom near the Gulf outlet. OYSTER COLLECTIONS Year VI - The oyster stations were located along the edge of the channel in deep water. Oysters were sparse, this year because the Louisiana Fish and Wildlife Department had removed most of them in a replanting project. Stations were not distinguished due to the sparse population. Three hours of dredging was required to obtain 90 oysters. This station should improve in future years since the area is closed to commercial luggers. Years V71 & V711 - Oysters were not collected at during these years. SEDIM]ENT COLLECTIONS Year V1'- The only suitable sediments were found in deep water along the edge of the channel. All of the south end of the Lake had hard packed sandy bottom. Station 2 was located at the coordinates given for the oyster collection. Station 1 was located 200 m to the northwest and Station 2 was 300 m to the east. Sediments can only be obtained by a box corer equipped with a 10 m rope and a messenger. Years WI & VIII - Sediments were not sampled these years. 333 SAMPLING M[E1U0DS Oysters - dredge Sediment - box core attached to a rope WATER DEPTH - Oysters 4 to 5 m and greater than 5 m for sediment. POSSIBLE CONTAMINANTS - No obvious pollution sources were evident, but Lake Pontchartrain drained through this outlet and tidal water ftom New Orleans flushed back into the lake. There was also abundant boat and ship traffic.

From Year II on, access-to the site was via automobile, taking the first exit on the west side of the bridge at Highway 90 and following the road south along the shoreline to Veterans Pier. A boat ramp was located on the south side of the jetty/pier for sediment sampling. SITE DESCRIPTION - In the first year oysters were tonged from the open water offshore from Bay St. Louis (30'17.75'N and 89'19.60'W). The original reef location off Pass Christian was dead in Year II and the site was moved onshore to the Veterans Pier. At the pier, oysters were attached to rocks and on the muddy sand bottom. Accessibility was best at low tide. OYSTER COLLECTIONS Year I - Year I stations were located in Bay St. Louis. Station 1 was approximately 0.5 to 0.75 miles south of the railroad bridge. Bearing to landmarks were: 70' to the silver water tower, 230' to the center pivot trestle, and 3500 to the buoy marker. Station 2 was 200 m north of Station 1 and Station 3 was 200 m farther north. Years 11 & III - During Year II no oysters were found at the Year I site. In Years II and III, the site was moved to the Veteran's Pier at Bay St. Louis. The oysters were intertidal and were collected by hand without the use of a boat. Station 1 was on the north side of the jetty. Station 2 on the seaward side of the "T" end of the jetty and under the pier. Station 3 was on the south side of the jetty. Year 1'V - In Year IV, the site was the same as in Year II & III, on Veteran's pier. Stations were located as before. Construction was in process along the shore, jetty and, pier and sand had been filled on the beach. Additional rock rubble had been added to the "T" end of the jetty, covering most of the oysters at Station 2. However oysters were more plentiful and larger than in the past. Year V - Stations were in the same locations as previously sampled. Oysters were very scarce due to the recent freeze which had killed all oysters above the low tide line. Year V1 - There were no live oysters at Stations 2 and 3. At Station 1 there were very few live oysters attached to the concrete rubble but there were numerous oysters at a small reef 20 m north of the north end of the "T" 339 end of the jetty. All three stations were collected on this small reef. Stations were not differentiated. Year VII - This site was not sampled this year. No live oysters could be found at any of the previously sampled sites nor in the surrounding bay. Year V111 - No oysters were present at the Veteran Pier, so the site was mosed 1.65 nm to the NE (bearing 57'). The site is located at a submerged reef which parallels the Highway 90 bridge. The reef lies 10 meters south of the bridge on the east side of the channel in 2.5 rn of water. Oysters were numerous but since the reed is small, individual stations were not recognized. Loran coordinates for the new reef are 30" 18.87'N and 89' ..18.05V. SEDIMENT COLLECTIONS Year I - Sediments were taken at 100, 150 and 175 rn south, respectively, from each oyster station. Year II - Sediments were obtained by box coring directly offshore from the jetty at distances of 200, 400, and 600 m, respectively, for the three stations. Year 111 - Sediment stations were collocated with each oyster station. Silty- sand sediments were collected along the shoreline and can be reached by wading. Years IV, V, VI, VII, & VIII- Sediments were not sampled during these years. SAMPLINGMETHOD Oysters - tonging and hand Sediment - box core and hand WATER DEPTH - 0 to 3 meters (subtidal in Year I, intertidal in succeeding years) POSSIBLE CONTAMINANTS - There were no obvious sources of contamination nearby.

Access to the site is via automobile, parking at the Marine Education Center on Highway 90 at the Biloxi-Ocean Springs bridge. SITE - DESCRIPTION - The sample area was along the shoreline in intertidal waters. Oysters were taken from the concrete bulkhead, rocks and debris in the water. There were a limited number of oysters at this location. OYSTER COLLECTIONS Years 1, 11 & III - The stations established in Year I were collected the next two years also. Station 1 was adjacent to Marine Education Center. Station 2 was next to the west end of the bridge on the south side. Station 3 was northeast of the bridge -150 m from Station 2. Year I-V - In Year IV, the stations were: Station 1, under the bridge at the second and third support from the west end; Station 2, at the first pier support under the bridge; and Station 3, on the shoreline bulkhead and into the bay. As before the oysters were collected by hand from the concrete pilings, piers and concrete rubble. Year V - Stations 2 and 3 were in the same locations as sampled last year. Station 1 was moved from under the bridge to 125 m up the shoreline to near the point north of the bridge. This station was moved due to the lack of live oysters. A freeze had recently killed most of the oysters. Year VI - Stations 2 and 3 were again at the locations sampled last year. Station 1 had not recovered from the freeze, so it was collected north of the bridge on a concrete bulkhead. Oysters were numerous at this site. Year V11 - No live oysters could be found at any of the stations this year. Year V111'- Oysters were again present and were collected at the locations described for Year V. SEDDIENT COLLECTIONS Years 1, 11, & III - Sediments were taken offshore from the three oyster sampling locations, with the boat being launched at the city marina -0.25 mile to the east from the Mareing Education Center. 345 Years IV, V, VI, VII, & VIII - Sediments were not sampled during these years.

SrIE NLJAMER 35 DESIGNATOR - MSPB SITE - PASCAGOULA BAY, MISSISSIPPI SOUND MS LATrITJDE 30020.03'N 88036.10V LOCATED ON NOS CHART 11374,11373 SITE ACCESS - To reach the boat ramp on the Pascagoula River turn off Highway 90 onto Market Street going south. When the road dead-ends at the beach, turn right and drive west to the end of the road. The boat is launched at the public ramp. Then by boat proceed west to red channel marker 4. Run time to the site is less than 10 minutes. SITE DESCRIPTION - The site was located west of the new causeway going to the Naval Base near the mouth of the West Pascagoula River. Oysters were generally abundant and were found by poling the subtidal reef. Soft mud sediments were found adjacent to the reef at each collection point. Oysters were abundant. OYSTER COLLECTIONS Years I, II, & III - Year I stations were centered around red channel marker 4. Station 1 was 100 m east of red channel marker 4. Bearing to permanent landmarks were: 801 to grain elevators and 260' to Bellefontaine Point Lighthouse. Station 2 was at the red channel marker 4 (80' to grain elevators; 255' to the lighthouse ). Station 3 was. 150 m west of red channel marker 4 (80' to the grain elevators and 262' to the lighthouse). Oysters were collected by tonging. Year rV - As in Year III, the site was centered around channel marker 4 which was just west of the new causeway and west of Ingalls shipyard. Station 1 was about 100 m east of the marker in shallow water which had been affected by silting from dredging operations. Oysters were smaller and fewer live ones were present than at other stations. Station 2 had to be moved from the marker to about 200-300 m north of the marker where a small iron pipe and a cane pole marked the channel. Oysters here were prolific and fairly large. Station 3 was 150 m west of the marker. It also had oysters in abundance. The whole area around the site was closed to oystering by the health department. Oysters were collected by dredging. Year V - Stations were located in the same areas as sampled last year. Oysters were collected by tongs this year. Year Vr - The site was centered around channel marker 4 (30'20.55'N, 88'35.96'W). Station 1 was 100 to 200 m east of the marker. Station 2 was at channel marker 4. Station 3 was 100 to 200 m west of the channel marker. Oysters were very abundant at all three stations. Years VII & VIII All three stations were centered around channel marker 4. Station 1 was in the same area as last year, 100 to 150 m east of the marker. Station 2 was moved slightly north (50 to 150 m) of the marker. Station 3 was 150 m west of the marker. Oysters were abundant at all three stations. SEDIM]ENT COLLECTIONS Years 1, 11, & III - Sediments were gray and brown mud mixed with sand. Collection sites were north of each site within 75 to 100 m. Years IV, V, VI, VII, & V111 - Sediments were not samp led during these years. SAMPLING METHOD Oysters - tongs and dredge Sediment - box core WATER DEPTH - subtidal, 1 to 1.5 meters POSSIBLE CONTAMINANTS - Possible contamination sources included the Pascagoula River, City of Pascagoula, Naval Ship Yard, heavy marine traffic and nearby industries.

The site is located directly east of the middle part of Cedar -Point. At low tide the site can be reached by walking across the shallow sandbar on the north end of the reef. By boat the site is 10 to 15 minutes from the launch site. SITE DESCRIPTION - The site was located on an oyster reef 0.25 mile offshore and east from the highway leading to the causeway bridge to Dauphin Island. The reef was almost due east of the Cedar Point fishing pier which was on the west side of the highway. OYSTER COLLECTIONS Year I - Oysters were tonged from 2-3 m of water at a site approximately 0.75 miles east of the Dauphin Island highway. Station 1 was at bearings 180' to center of ICW bridge; 2800 to Alabama Port Point, and 134' to Fort Gaines. Station 2 was 500 m to the south at bearings 1800 to the center of ICWW bridge; 2831 to Alabama Port Point and 133' to Fort Gaines. Station 3 was 300 m southeast of Station 2. Bearing to local landmarks were 178' to center of the ICWW bridge; 278' to Alabama Port Point, and 122' to Fort Gaines. Year H - Sampling stations were distinguishable during Year I but not in Year II because of the scarcity of the oyster population. Oysters were purchased from a commercial tonger who had been working for 7 hours to tong only 180 oysters. Year III - Year III oysters were tonged east of the causeway on a submerged reef. Station 1 was on the south end of the reef. Station 2 was 50 m north of Station 1 and Station 3 was another 75 m to the north. There were several oystermen tonging in the immediate vicinity. Year IV - In Year IV, the oysters were sampled by hand at low tide on a sand and shell reef to the east of the causeway adjacent to the Cedar Point fishing pier. Station 1 was at the south end of the reef, Station 3 was at the north end; Station 2 was in the middle. Total distance from Stations 1 to 3 was 150 m and water depth at low tide was 0.2 m. The oysters were not abundant. Year V - Sampling stations were located on the same reef in the same positions as sampled last year. Oysters were very sparse, perhaps because of the recent freeze. 357 PF Year VI - Oysters were collected at the same locations again this year. Oysters were more abundant this year. Years VII & VIII - Oysters sites were at the same locations as described in Year IV. SEDIMENT COLLECTIONS Year I - Sediment sites in Year I were 25, 125 and 115 m east, respectively, for each station. Year Il - Sediment sites were south from the oyster sites in close proximity to the bridge pilings. Station 1 was located at the eighth bridge pillar from the north end of causeway; Station 2 was 0.25 mile south of the north end of the causeway bridge and 25 m to the east; and Station 3 was taken east of the south end of the cut-off bridge where the boat was launched. Year III - Sediments were collected adjacent to the bridge. Station 1 was at the eighth bridge pillar from the north end of the causeway. Station 2 was at the second set of telephone poles east of the causeway. Station 3 was on a submerged reef 75 m north of Station 2. The bottom was primarily sand, shell and silt. Years IV, V, VT VIT & VIH - Sediments were not sampled during these years. SAMPLING METHODS Oysters. r. tongs and hand Sediment - box core WATER DEPTH - intertidal to subtidal, 0.2 to 1.2 meters.

Launch at the Beach Comber and proceed out the Dog River channel to channel marker 10. Turn south and start poling for oysters. SITE DESCRIPTION - This collection site established in Year III was in the upper reaches of Mobile Bay and was near th6 upper distributional limit of oysters in the bay. OYSTER COLLECTIONS Year III - Oysters were located in 2 m of water on small scattered reefs with oysters, shell and clams. Oysters were difficult to locate and were collected by tonging. Station 1 was directly south of red buoy 10 in the Dog River to Biloxi channel. Station 2 was 75 m to the south of Station 1. Station 3 was another 75 m south. Year IV - In Year IV, the oysters were collected by tonging on a small and sparsely populated reef about 100 m southwest of channel marker 9 and an equal distance southeast from a 4 legged wooden stand, just east of the Dog River marina. Station 1 was at the north end. Station 3 was at the south end, and Station 2 was in the middle. Water depth was 2 m, and the reef can only be located by poling the bottom. Oysters came up mostly from the shelly mud bottom as singles, and large aggregations were not found. The bottom was a mixture of sand, mud and shell. This site is best collected in calm weather. Year V - Oyster stations were in the same general locations as sampled last year. The oysters were sparse. This site required all day to complete since it required poling and tonging to locate and collect the oysters. Year VI - Oysters were collected at the same stations described in Year IV (30033.88'N, 88004.58'W). Years V11 & V711 - Oysters were collected at the same stations described in Year IV, but were dredged these years. Oysters were still not abundant either year. SEDEMUKNT COLLECTIONS Year III - Sediment stations are collocated with each oyster station and must be located by poling. Years I-V & VI - Sediments were not sampled during these years. ,%3 Year V - Sediment samples were taken at the same locations as the oyster samples. Years VII & VIII - Sediment samples were not taken these years.

SITE DESCRIPTION - This collection site was established in Year III. It was located in Pensacola under the Pensacola Fishing Pier which was the old Highway 98 bridge. The pier was on the east side of the new bridge. Collections from this site were easiest at low tide and in calm weather since the boat had to be tied to the piers. OYSTER COLLECTIONS Years III & I-V - Oysters were collected by hand from concrete piling under the bridge. Oyster Station 1 was at the seventh set of pilings from the north shore. Station 2 was at the eleventh set of pilings. Station 3 was at the fifteenth set of pilings. All oysters collected were intertidal. Year V - Oysters were collected in the. same locations as sampled last year. There were many recently dead oysters on the upper part of the piling. This was primarily due to the recent freeze. Years VI & VII - Oysters were collected at the same locations as previously sampled. Oysters were larger and more abundant. Year VIII - Oysters were collected at the same stations previously sampled, but were more abundant. SEDIM[ENTCOLLECTIONS Years III, I-V & V - Water depth at the site was -7 m. No sediments were collected because of the depth. Substrate near the boat ramp was sandy. Year W - No sediment samples were collected this year. Year VII - Sediment samples were collected for the first time at 30'24.14N and 87'11.38W. Suitable sediments were located in 6.2 m of water and were collected with a box corer. Three stations were collected 50 m apart on a line starting at the 45 mph sign on the bridge running toward the north. Year V111 - No sediment samples were collected this year. 375 SAMPLING METHOD - Oysters were collected by hand from the concrete pilings of the old bridge in the intertidal zone. The site can only be collected in calm weather since the oysters are collected by hand from the boat.

Proceed to a dirt road intersection, turn left and proceed to a dead end at Indian Bayou. Launch the boat at the small ramp and proceed down Indian Bayou to its mouth. In Year IV, the mouth of Indian Bayou had silted in, so the launch point was moved. To reach the boat ramp, exit I-10 at Avalon then go north to SR 281. Turn left and go to the stop sign, turn left again and follow the dirt road until it ends at the Archie Glover Park. To reach the site, follow the marked channel out to Escambia Bay and then turn south going under the bridge to the reef. The reef is located about 1 mile south of the bridge on a bearing of 140'. Run time to the site is approximately 20 min. SITE DESCRIPTION - There was generally an abundant supply of oysters at this location. Year I oysters were collected by hand near the mouth of Indian Bayou at 30'31.35'N and 87'06.38'W. In Year II the site was moved to a more permanent location. Oysters sites were located on a subtidal reef west of the entrance to Indian Bayou. The site was marked by several pilings, one of which had an "Oyster Reef' sign. The site was located between the poles marked "Danger, Oyster Reef." OYS= COLLECTIONS Year I - Year I oysters were collected by hand near the mouth of Indian Bayou. Station 1 was 30 m north of Indian Bayou. Bearing to landmarks useful in locating the site were: 292' to factory towers; 249' to the water tower. Station 2 was 50 m south of Indian Bayou (290' to the factory towers; 248' to the water towers). Station 3 was 30 m south of the bayou mouth in the bayou. Years II, Ill"& rV - The site was moved out into the bay in Year Il. Oysters were tonged from three locations along the reef. Station 1 was at the northeast end of the reef; Station 2 was 100 m southwest of Station 1, near the poles marking the reef-, Station 3 was 100 m southwest of Station 2, near the "Danger" sign. Year V - No oysters were available for collection at this site due to high volumes of freshwater inflow which had recently killed all of the oysters. Year VI - The oyster reef was recovering from the dieoff experienced in Year V. Station 1 was at the northeast end of the reef between the two poles marking the edge of the reef. Station 2 was on the middle of the reef between the two middle poles. Station 3 was on the south end 381 of the reef due north of the last pole. This narrow reef was oriented north to south. Oysters were mixed in black silty mud that has apparently silted over the underlaying shell reef. Years V11 & VIII - The oyster reef was still recovering from the dieoff experienced in Year V. Oysters were only found at Station 2 which was located in the middle section of the reef between the two middle poles. SEDIMENT COLLECTIONS Year I - Sediments in the area were primarily shell and sand. The best source of fine grained sediment was located in Indian Bayou. In all years, sediments were taken from Indian Bayou. In Year I, sediment stations were collocated with the oyster stations. Years 11'& 111 - Sediments were taken as follows: Station 1 was from the narrow bayou opening to the bay. Station 2 was along the north shore of the bayou 300 m from the mouth and 30 m from shore, and Station 3 was 100 m northeast of Station 2. Years I-V, V, V1, V11, & VIII - Sediments were not sampled during these years. SAMPLINGMETHOD Oysters - hand, tongs and dredge Sediment - hand or box core WATER DEPTH - intertidal, 0.3 - 1 meters (Year I), subtidal, 2 meters, in subsequent years. POSSIBLE CONTAMINANTS - There were no observable sources of contamination.

To reach the site cross the Pensacola Bay Bridge on Highway 98, go through Gulf Breeze to Shoreline Drive. Turn right and go to the Shoreline Drive Park. Turn left and continue to the boat ramp on the north side of the Santa Rosa Sound. SITE DESCRIPTION - This collection site established in Year V is located in Santa Rosa Sound. The site is located under the Highway 399 bridge on the south side of the ICWW. Collections from this site are easiest at low tide and in calm weather since the oysters are attached to the concrete piers. OYSTER COLLECTIONS Year V - Oysters were collected by hand from concrete piling under the bridge. Oyster Station 1 was the first 7 sets of piers on the south side of the bridge. Station 2 was directly north of the first station and included the next nine large concrete piers. Station 3 was the next eight piers to the north on Station 2. The site ends at the channel. All oysters collected were intertidal. Numerous oysters were dead due to the recent freeze. Year VI & V11 - Oysters were not sampled these years. Year Vl'l"-T - Oysters were collected at the stations described for Year V. SEDIMENT COLLECTIONS Year V - Sediments were collected approximately 1 mile to the northeast, along the shoreline at latitude 30121.03'N and longitude 87009.35'W. Sediments were primarily sand. Year Vi, Vii, & VIII - No sediments were samples were collected these years. SAMPLING METHOD - Oysters were collected by hand from the concrete pilings of the old bridge in the intertidal zone. The site can only be collected in calm weather since. the oysters are collected by hand from the boat.

The site is located just south of the boat ramp. SITE DESCREPTION - The site which was established in Year rV was on the south shore of Choctawahatchee Bay between the other two Choctawhatchee Bay sites. The site was located at the mouth of Joe's Bayou where it enters the Bay. The collections were taken from the area directly south of the. boat ramp, the oysters were intertidal and accessible by wading from shore. More oysters were available farther up the bayou along the shoreline structures. Access to these sites had to be by boat because the surrounding grounds were all private homes. OYSTER COLLECTIONS Years 1-V & V - The three stations were along the shoreline with Station 1 at the launch/pier; Station 2 next; and Station 3 as far south as one can go before encountering the private dock. The total distance spanned only 50-100 meters. Year VI - The same stations as were sampled in Year V were collected this year. Oysters were numerous but small. Years V11 & VIII - The same stations described in Year IV were sampled these years. SEDIMENT COLLECTIONS Year 1V - No sediments of anything other than hard packed sand or fresh humic materials composed primarily of pine needles could be found. The upper reaches of the bayou and the mouth out into the bay were checked. No sediments were obtained because none met the sampling criteria. Year V - Suitable sediments were located in the southern arm of the upper part of Joe's Bayou in 1.5 m of water. Station 1 was 30 m from the west shoreline between the wood boathouse and the two boat pier to the north. Bearing to locate the station was 120' to the Destin water tower. Station 2 was in the northeast arm of upper Joe's Bayou near the end on the north shore between the last and next to last boathouse. Water depth was 1.2 m and the sediment was very loose brown silt. Station 3 was across the bayou (east) from Station 2, between last boat house and boat house #016. 393 Years VI, VII, & VIII - No sediments were sampled these years. SAMPLING AIETHODS Oysters - hand Sediment - box core WATER DEPTH - intertidal, 0 to 0.6 meter POSSIBLE CONTAMINANTS - There appeared to be no drainage other than rainfall runoff from the immediate area into the bayou, and its proximity to the bay suggested that it was fairly representative of the bay. No obvious sources of contaminants were apparent except for a sand and gravel transfer yard immediately to the north of the site.

Access to the site is by boat launched from ramps on either side of the south end of the bridge crossing Choctawatchee Bay or- at the Yodiim's Grocery ramp north of the drawbridge. From the drawbridge proceed west to channel marker 34 on the ICWW. SITE DESCRIPTION - Two distinct locations have been sampled for this site. In Year I, oysters were tonged south of the channel marker 34. The subtidal oyster reef was extensive and the outer margin of the reef was marked with four wood pilings. However, in Year II & III, no oysters could be found in the subtidal sampling area and the site was moved to the shoreline where a small bayou enters the bay (southeast from a large white house) at latitude 30'24.35'N and longitude 86'12.75'W. Oysters were attached to rocks and a wooden bulwarks around a large tree. Oysters were small and not overly abundant. The site was moved in Year IV due to oyster depletion at the shoreline site. In Years IV, V and VI, oysters were tonged southeast of channel marker 40 (30'24.53'N, 86'11.40'W). OYSTER COLLECTIONS Year I - The oyster reefs south of channel marker 34 were tonged for oysters' This site was approximately 1 mile west of the drawbridge and 1 mile north of the south shoreline. Oyster stations were located on a south to north line with Station 1 being on the south end. Station 1 was approximately 300 m south of channel marker 34 on a bearing of 250'. Other bearings to locate the station were: 300' from the south end of the drawbridge,- 108' from south Live Oak Point, and 350' from the microwave tower. Station 2 was approximately 100 m to the north and Station 3 was another 100 m to the north near the channel marker. Year 1I - No oysters could be located in the area sampled during Year 1, so the site was move to the shoreline. To reach the shore site, take a bearing of 70' from channel marker 34 to a small bayou. This site was southeast from a large white house on the shore. Oysters were attached to wood and rocks along the bank. No significant geographic distinction could be made between the oyster stations because of the paucity of oysters. Year III - Oysters were again collected from the rocks and wood pilings. Stations were segregated with 50 meters between locations. 399 Year IV - In Year IV, the site was relocated to a commercially fished reef near channel marker 40 (bearing 062' to the marker). The reef ran northeast-southwest (260/0801) and was marked by poles and signs "Danger, submerged oyster reefs". This reef was in 3 m of water and had to be sampled by tonging. Station I was at the southern end of the reef about 50 m north of the last pole. Station 2 was 30 m south of the "Danger..." sign, near the middle of the reef. Station 3 was at the northeast end of the reef, bearing 240' from channel marker 40, and 15 meters west of the northern most pole marking the reef. Year V - Stations were located in approximately the same locations as last year. Oysters were sparse due to recent die-offs, and many recently dead oysters were tonged. Station 1 was 30 m south of the southmost pole on the west side of the reef, between the two poles marking the south'end of the reef. Station 2 was in the middle of the reef, 15 m south of the second pole from the north. Station 3 was at the northeast end of the reef, between 15 and 50 m west of the northmost pole. Year VI - Stations were in the same locations as last year. Oysters were dredged and were more abundant this year. Years VII & VIII - Oysters were dredged from the same stations sampled the previous three years.. Oysters were abundant both years but were covered with numerous mussels. SEDEMENT COLLEMONS Year I - Sediment samples in Year I were collocated within 30 m of each oyster station. These sediments were a charcoal gray to black mud overlain by dark brown surface. Year H - Sediments sampled were a loose black mud taken on a line from the oyster collection site on shore toward channel marker 34. Station 1 was 500 m from channel marker 34 marker with Stations 2 and 3 being 400 and 300 m from the marker. Sediments shoreward of this point (nearer the oysters) were much too sandy. Year III - Sediment stations in Year III were collected on the same line at distances of 100 m apart on a line to channel marker 34. Year IV - No sediments were sampled. Year V - Sediment samples were black silty sand mixed with oyster shell and were collected near each oyster station. Station I was collected 30 m north of the pole at the oyster station. Station 2 was 30 m north of the pole at the oyster station. Station 3 was also 30 m north of the pole at that oyster station. Year VI - Sediments (NIST) were collected adjacent to each oyster station. Years VII & V111 - No sediments samples were collected these years. SAMPLWGMETHOD Oysters - tongs and hand Sediments - box core WATER DEPTH - subtidal, 2 - 3 meters (Years I, IV, V, VI) and intertidal, 0-0.3 (Years II & III) POSSEBLE CONTAMINANTS - No sources of contamination were evident in the area.

The park is located at the east end of the Hathaway Bridge (Highway 98) on the north side where it crosses West Bay. Cross the bridge.-then turn north on Moody Avenue to the old highway. Turn left and the ramps are on the right. In Year VII the boat was launched at the Leslie Port Wayside Park boat ramp which in on Highway 77 on the north side of Panama City. SITE DESCRIPTION - The site was not established until Year IV of the program and was located at Little Oyster Bar Point in North Bay. The site was on the edge of the U.S. Air Force Petroleum Depot. The oyster and sediment sites were separated across the bay by a distance of about 2 miles. The sediment site was located near the mouth of Mud Bayou and east of West Bay Point. OYSTER COLLECTIONS Years IV & V - Oysters were taken from the concrete bases of the high voltage transmission towers crossing the bay at Little Oyster Bar Point. Station 1 was on the tower on the shoreline. Station 2 was the next tower from the east shore (southeast of channel marker 6). Station 3 was the second tower from the east shore (north of channel marker 6). Station 1 could be collected as a walk-up station, but the other two stations had to be sampled from the boat. Year VI - All three stations were collected at the same locations previously sampled. Station 1 was depleted of oysters and will have to be moved next year. This was partially due to siltation occurring around the base of the concrete pilings and at the mouth of the small pond which blocks the tidal flow at this site. Year VII - Station 1 was completely silted over and no oysters were present; therefore, it was moved to the northwest side of the bay. The new site was established at the second set of transmission piers out from the north shoreline. The new site was located at 30'15.59 north and 85'41.13 west. Stations 2 and 3 remained at the locations previously sampled. Year VlIl'- Collection stations remained the same as described in Year Vii. 425 SEDIM]ENTCOLLECTIONS Years IV & V - Sediments were collected at the mouth of Mud Bayou (30'14.27'N and 850 42.69W). Station 1 was to the north of the Bayou. Station 2 was just to the south of the mouth at the sandy beach. Station 3 was 300 meters south of the Bayou mouth. All stations were sampled in 0.2 meters of water approximately 25 meters from the shoreline. There were oysters scattered in the grass beds and several small reefs in this area but oysters were too few and scattered to be reliable for repeat sampling. Years V1, VII, & VIII - Sediments were not sampled during these years. SAMPLING AURTHODS Oysters - hand Sediment - box core WATER DEPTH - intertidal, 0 to 0.3 meters. POSSIBLE CONTAMINANTS - Possible contamination included a military fuel depot at Little Oyster Bar Point and a coal burning power plant across the bay.

A boat is necessary to collect this site and is launched at the public boat ramp. All three stations are located at the marina. SITE DESCRI]PTION - This site was not established until Year III and was located at the Bay City Marina. The stations were placed inside and at the entrance of the marina. OYSTER COLLECTIONS Year III - Station 1 for both oysters and sediments was located inside the breakwater on the east side of the marina. Oysters were collected along the breakwater and were numerous at and to 0.5 m below the normal high tide line. Station 2 was located opposite Station 1 on the outside of the breakwater. Oysters were slightly less abundant but were still numerous. Oyster Station 3 was located north of Station 2 and outside the breakwater. It was directly east of the parking lot which was north of the boat ramp. Oysters were collected from a submerged concrete mass but were also found below the tide line of the breakwater. Years IV & V - In both years, the collection sites were the same as was first sampled in Year III. Station 1 was inside the harbor on the bulkhead directly southeast of the boat ramp. Station 2 was outside the marina, directly opposite Station 1. Station 3 was directly north of Station 2 along the concrete bulkhead next to the parking lot at the boat ramp. Years VI & VII - Oysters were not sampled at this station during these years. Year VIff - Oysters were collected at the stations described for Year III. SEDEM3MW COLLECTIONS Year III - The only fine grained sediments were at the base of the bulkhead at Station 1. No suitable sediments were found in the vicinity of Stations 2 and 3, nor in any location near the marina. Years rV & VI - No sediment samples were collected during these years. Year V - Sediment samples were collocated with each of the three oyster stations. 431 Years W1 & VIII - Sediments were not sampled these years.

After collection of the Municipal Pier site travel by east down the ICWW to Watson Bayou. The site is at the first point on the right (east side) after entering the Bayou. SITE DESCRIPTION - The oysters were attached to rocks on a point of land identified by a former shipyard, just west of the dockage for ships and boats on the channel that led up to the paper mill. Oysters were intertidal, small and sparse. OYSTER COLLECTIONS Years 1, 11 & 111 - All the oysters were collected at the same location in Years 1, 11 and III. No significant geographic distinction could be made between oyster stations. Landmarks to locate the site were: 352' to the white oil tanks; 78' to the tall smoke stack. Years X, V, VI, VII, & VIII - The site was the same as in previous years. All stations were taken from the rock rubble along the shore on the first point on theeast side of Watson Bayou. SEDIMENT COLLECTIONS Years 1, 11, & III - Sediments in the entire bay area were coarse sands, except for the upper reaches of the slough leading to the paper mill. Sediments were sampled just south of the small bridge at the paper mill (Station 1), across the channel from the paper mill (Station 3), and slightly upstream (near the outfall pipe) from the paper mill near the upper end of the slough (Station 2). The.sediments were a black ooze with the consistency of pudding. Sediments and the air had a peculiar and unpleasant odor. Years IV & VI - No sediment samples were collected. Year V - Sediment samples were in the same locations as sampled during the first three years. Years V11 & V111- Sediments were not sampled these years. 437 SAMPLINGNETROD Oysters - hand Sediments - box core WATER DEPTH - intertidal, 0 - 0.5 meters POSSIBLE CONTAMINANTS - Probable contamination would be expected from the dockage facilities around the corner from the site, fuel oil storage and transfer facilities around the embayment, and the effluents from the paper mill.

Park and walk to East Point Beach where oysters can be picked up by hand at low tide. If the tide is high the boat can be launched at one of the ramps on Highway 30, which is east of the site. SITE DESCRIPTION - The site was located at Cat Point. The reef was exposed at low tide and was the major source for oysters in eastern Apalachicola Bay. At high tide the oysters were collected by tonging. OYSTER COLLECTIONS Year I - Oysters were collected by hand along the exposed reef. Station 1 was 100 m off the beach, south of East Point. Station 2 was located 100 m south of Station 1 -200 m offshore. Station 3 was east. of Stations 1 .and 2 -25 m offshore. Year Il - During Year II, the boat was launched from the ramp in the boat basin at the town of East Point (two blocks south of Highway 98). It was a five minute ride to,the tonging site on a large reef that parallels the telephone poles crossing the bay. The oyster site was 200 m east of telephone pole #6 (bearing 260' to sixth pole from shore). Oysters were abundant but tonging was required; dredges were not permitted in Apalachicola Bay. Oysters were collected for all stations at one place in Year II. Years III, IV, V & VI - Samples were taken at the Year II station locations. However, since the tide was low, the oysters were collected by hand and separate stations were established. Oysters stations were -100 m apart. Station 1 was at the north end of the reef, Station 2 in the middle and Station 3 -was at the south end. Years V11 & VIII - Samples were taken at the same locations described for Year III. SEDEMEENTCOLLECTIONS Year I - Sediments for the first year were located just off the reef (east and northeast) collocated with each oyster station. The sandy mud sediments were as fine a texture as could be found in the area. 449 Year 11 - Sediment Station I was located 500 m east of #6 pole. Station 2 was 500 rn east of the 8th pole. Station 3 was 500 m east of the 4th pole. The substrate was sandy mud with small shell fragments. Year III - Sediments were collected 500 m east of the oyster stations. Sediments were fine silt over sand. Years IV, V, VI, VII, & VHI - Sediments were not sampled during these years.

Turn right and go to the end of the road. The Spears Seafood Company at the end of the road has a launch that can be used. Proceed out the marked channel to the collection site. SITE DESCRIPTION - This site, which was established in Year IV, was located on the west side of Apalachee Bay where Spring Creek enters Oyster Bay. Sampling stations were located in the midst of very prolific reefs where Spring Creek entered Oyster Bay. The site was located along an "S"- shaped reef 300 in south of channel markers 31 and 32, and northwest to southwest of channel markers 29 and 30. OYSTER COLLECTIONS Year I-V - Year IV oysters were sampled by hand from the intertidal parts of the reef. Station 1 was at the north end of the exposed part of the reef which extends as a subtidal portion farther north into the marsh. Station 3 was at the south end of this reef. Station 2 was located.on the east side of the reef, mid-way between 1 and 3. Reef length was 300 m. Year V - Collection locations were the same as established last year. The number of oysters were much reduced from last year. Most of the reef was composed of dead shells. Year VI - Station locations were the same as last year. Oysters were more abundant than last year. Years VII & VIII - Station locations were at the same sites as originally established in Year IV. SEDEMIENTCOLLECTIONS Year I-V - Sediments for Station 1 were taken about 100 m from the reef, midway and on a line from the north end of the reef to channel marker 29. Stations 2 and 3 sediments were located adjacent to the oyster stations about 25 and 50 m, respectively, from each station on the east side of the reef. Year V - Sediments were collected adjacent to each oyster station. Station 1 was from the west side of the reef 10 m from the shoreline. Station 2 was also on the west side of the reef 10 m from the shore adjacent to the oyster station. Station 3 was 5 m from the reef on the west side. 455 Sediments were composed of fine grained black silt in pockets over shell and shell hash. Years VI, Vii, & VI11"- Sediments were not sampled during these years. SAMPLINGMETHODS Oysters - hand Sediment - box core WATER DEPTH - intertidal, 0 - 0.5 m. POSSIBLE CONTAMINANTS - There were no obvious contamination sources, although the site was located in waters which were closed and/or conditional to shellfish harvesting.

SITE DESCRIPTION - This site was established and sampled only in Year III. Oysters were collected along the margins of Cat Island. Reefs were numerous east of Cat Island and were exposed at low tide. The margins of the islands were covered with Spartina alterniflora. OYSTER COLLECTIONS Year Iff - Oyster Station 1 was located on the northeast shore of Cat Island between a topless palm and a pole in the water. At low tide the reef is exposed and numerous small oysters are present. Oysters can be collected by hand or tonged. Station 2 was a subtidal reef with an exposed intertidal portion. It was located between Cat Island and a small island to the northeast. Station 3 was -50 m north of Station I on the north side of the same reef. Oysters at all three stations could be collected by hand at low tide but had to be tonged at high tide. Years IV, V, VI, VII, & VIII - The site was not sampled during these years. SEDDMENT COLLECTIONS Year III - Sediment Station 1 was collected along the intertidal marsh on the east side of Cat Island. Station 2 was in a small inlet directly east of the second oyster station. Sediment was a peaty/organic sandy mud. Station 3 was collected several hundred meters away from the other station. This station was collected when returning to the ramp, after a turn north at channel marker 22 into a cove that ran west from the main channel. A sawgrass marsh surrounded this site and the sediments were an organic peaty mud. 461 Years IV, V, VI, VII, & VIII - Sediments were not sampled during these years. SAMPLINGMETHODS Oysters - tongs and by hand Sediment - box core WATER DEPTH - intertidal, 0 - 1 meter POSSIBLE CONTAMINANTS - No contaminant sources were identified at this site.

SITE NUTAMER 43 DESIGNATOR - CKBP SITE - BLACK POINT, CEDAR REY FL NOMINAL SITE CENTER - 29012.32'N 83004.25W LOCATED ON NOS CELART # - 11408 SITE ACCESS - Access to the site in Years I and II was by boat launched at the city boat basin at the end of Highway 24 in Cedar Key. Shoals require that the channel markers be followed from the city marina to Derreck Key. The oyster site is located on the northeast side of a "U" shaped island adjacent to channel marker 2 at Derreck Key. Approximate run time to the site is an hour. In Year III, the boat was launched at a boat ramp north of Cedar Key at the end of Highway 326 off of Highway 347. The ramp is very shallow and launching at low tide is difficult, but the site can be reached in less than 10 minutes. From the boat ramp go south - 1 km. SITE DESCRIPTION - Oysters were collected from the subtidal perimeter of the small island. At low tide there were numerous exposed oyster reefs. The oyster site was located at a crescent-shaped reef with smooth cordgrass onthe west side, west of an island with three palm trees and one topless palm. The stations were located inside the crescent. OYSTER COLLECTIONS Year I - Year I oysters were collected from the perimeter of the small island in subtidal and intertidal water. Station 1 was at the mouth of a creek 0.75 miles from Black Point on a bearing of 125'. Other bearings to locate the site were 245* from the radio tower, 285' from the bridge center, and 345' from the water tower. Station 2 was an exposed reef 220' from Station 1. Local landmarks had a bearing of 250' from the radio tower, 284' from the bridge and 350' from the water tower. Station 3 was 300 m from Station 1 on a bearing of 120'. Year 11 - Significant geographic differentiation of the oyster stations was not possible this year. Bearings to local landmarks were 2620 to channel marker 2, 149' to the Cedar Key water tower, and 3170 to green channel marker 5. The oysters were collected by hand from subtidal and intertidal clumps which made up the island. Year HI - In Year III, samples were collected in approximately the same location as Year II. The site was a crescent shaped reef covered with smooth cordgrass. An obvious landmark to locate the site was the three palm trees due east of the site. All three station were located from inside the crescent on the east side Station 1 was in the middle. Station 2 was on the north end. Station 3 was at the south end. Oysters were collected by hand and tongs. 467 Year IV - Year IV stations were collected in the same locations as Year III. Oysters were very small in large clumps and the shells were very thin. Year V - Oyster stations were in the same location as previously collected. . Oysters were much less numerous this year. Year VI - Collection sites remained the same as those sampled last year (29010.25'N, 83003.00'W), but oysters were smaller and less numerous. Year VII - Due to extremely low tidal conditions the boat could not be launched this year; therefore, the site was moved approximately 1 km to the north (29'12.28 north 83'04.34 west), adjacent to the boat launch area. There are numerous reefs in the vicinity of the launch area. All three stations were located on the south side of the launch area. Station 1 was 50 m south of the launch, Station 2 was 50 m farther south, and Station 3 was another 50 m to the south. Year VIII - Oysters were collected at the stations described for Year VII. SEDIMENT COLLECTIONS Year I - Sediments were collocated with each of the oyster stations. Year Il - Sediments were taken from isolated pockets of sandy, shelly mud on the inside curve of the island and were adjacent to each oyster station. Many shell fragments were present over the entire bottom. A box core and wading was required to locate and retrieve the sediment samples. Year III - Sediments in Year III were located within 5 m of the oyster stations and were sandy mud with some shells. Years IV, V, VI, VII, & VIII - Sediments were not sampled during these years. SAMPLING METHOD Oysters - tongs and by hand Sediment - box core WATER DEPTH - intertidal, 0.2 - 0.4 meters POSSIBLE CONTAMINANTS - The site was mainly open water and no sources of contamination were observed. The site was miles from any habitation, industry or port facility ofany size. Effluents from Suwannee River may have influenced the site. 468 ENVMONAWINUAL DATA Salinity Temperature Dates Sampled ("YOO) (OC) YEAR 1 14.3 23.0 27 February 1986 YEAR 11 23.0 20.0 28 February 1987 YEAR 111 31.0 14.0 19 February 1988 YEAR IV 26.0 18.0 28 January 1989 .YEAR V 25.0 18.0 29 January 1990 YEAR VI 23.0 16.0 29 January 1991 YEAR VII 24.0 17.0 30 January 1992 YEAR VIII 27.0 22.0 13 January 1993 469 1A, )i if A 3@4 f + LfW.

Turn south on Double Branch Road and proceed to State Street, turn left and go to the boat ramp at the end of the street. SITE DESCRIPTION - This site, established in Year III, produced the most abundant oysters collected in the Tampa Bay area. Substrate was primarily sandy mud with pockets of oozy mud scattered around the shoreline. OYSTER COLLECTIONS Year III - Oysters at all three stations were well developed and sorted. They were of moderate size and looked healthy. They were plentiful, were easily picked by hand and required little sorting. All three reefs were clearly visible and partially exposed at low tide, but were still easily accessible at high tide by wading. Oyster Station 1 was located - 50 m north of the boat ramp. The reef extended across water from east to west and was exposed at low tide. Station 2 was a small subtidal reef - 10 m east of the end of the boat ramp. Station 3 was 50-m southeast of the boat ramp where the creek forks on the east side of the channel. Year X - The same three stations were sampled in Year IV as were first established in Year III. The site remained closed to harvesting, and the oysters from external appearance and abundance appeared in good shape. Year V & V1'- The same stations were sampled again these year. Oysters were mostly alive and were in better condition than those at sampling sites to the north. Year V11 - This site was not sampled this year. Year VIII - Oysters were collected at the station described for Year III. SEDDEENT COLLECTIONS Year III - Sediments were collocated with the oysters. Sediments were collected with the teflon scoop directly from the bottom substrate. Year -TV - No sediments were sampled. 477 Year V - Sediment samples were taken adjacent to each of the oyster collection stations. Sediment was a thin silt layer over hard sand found along the edge of the mangroves. Station 1 was in a small cove on the west end of the reef. Station 2 was 20 m northwest of the oyster site along the shore. Station 3 was 20 m to the east in the small cove on the north side of the channel. Year VI - Sediments (NIST) were collected in the same locations described in Year V. Years VII & VIII - No sediments were sampled these years. SAMPLING METHOD Oysters - hand Sediment - hand WATER DEPTH - intertidal, 0 - 0.3 meters POSSEBLE CONTAMINANTS - Contamination at the site was not obvious, but mobile home and housing developments were present upstream from the collection site. No industrial contaminant sources were observed.

SITE NUMBER 44 DESIGNATOR - TBPB SITE - PAPYS BAYOU, TAMPA BAY FL NOMMMAL SITE CENTER - 27050.53'N 82'036.62W LOCATED ON NOS CHART 11413 SITE ACCESS - The site is accessed by boat or by driving to the site. By boat, depart the city marina in St. Petersburg and cross the west side of Tampa Bay to Papys Bayou (-30 minutes). Access to the site for sampling by wading is accomplished by driving to the Weeden Island Wildlife Refuge via Weeden Drive. In Year VII a boat was launched at Gandy Bridge Marina. The site was reached by traveling out the channel parallel to the highway to Tampa Bay and then south to channel marker 15, then turn west to the entrance to Papys Bayou. This ride takes approximately 20 minutes. SITE DESCREPTION - The oyster site in Year I was a small intertidal reef (found by following channel markers to where reef almost blocked channel) at the back end of the bayou and the mangrove roots along the adjacent shoreline. A wood and steel pier-type of structure was at the end of the bayou where samples were taken. In Year II, the station was moved to* within 100 rn of the old bridge at the end of Weeden Drive. OYSTER COLLECTIONS Year I - Oysters were collected on a submerged oyster reef surrounding an old wooden and metal structure on the east side of the bayou in a mangrove area. Landmarks to locate the site were 140' from the tall radio tower and 195' from the smoke stacks at the power plant. The sites were separated by 100 m. Year 11 - Year II collections were made in the same location. Oyster stations were not differentiated geographically this year. Year III - In Year III, we drove to the site and collected the oysters by hand. A large healthy reef was located 100 m from the wooden pier at the end of Weeden Pond. Oysters were numerous but distinct stations were not recognized. Years IV, V & VI - The site was in the same position as sampled in Year III. No station distinctions were made. The stations were on the first large reef south of the pier at the end of Weeden Road. The site was best accessed by wading from the pier. The Year III and IV site was approximately 100-200 m north of the site sampled in Year II. Oysters were very abundant and accessible. In Year VI the oysters were very small and many had died recently. Year VII - The same location was sampled again this year. Oysters were numerous but were very small. 483 Year VIII - Oysters were not abundant on the reef, so the site was moved 30 m to the fishing pier. SEDIMENT COLLECTIONS Years I & Il - Sediments from the oyster site were all sand and shell. Sediments were collected on Weeden Island north of Harbor Isle. Sediments were intertidal sands with some humic material. Year III - Sediments were collected along the mangrove-lined shoreline. Station 1 was at the small boat ramp. Station 2 was 50 m to the north around the point. Station 3 was another 30 m north in a small cove. The majority of the bottom was sand except along the mangrove tree .-margin (1-2 m zone) where fine-grained silt was found. Years X, V, V1, VII, & VIII - Sediments were not sampled during these years. SAMPLING METHOD Oysters - hand Sediment - box core WATER DEPTH - intertidal, 0 - 0.5 meters POSSEBLE CONTAMINANTS - Sources of contamination included heavy recreational boating in the restricted embayment, and an electric power generation plant near the bay.

SITE NUMBER 45 DESIGNATOR - TBHB SITE - HILLSBOROUGH BAY, TAMPA BAY FL NoNuNAL SITE CENTER - 27'051.28'N [email protected] LOCATED ON NOS CHART # - 11413 SITE ACCESS - The boat was launched at the ramp on the northwest corner of the Highway 41 bridge over the Alafia River. SITE DESCRIPTION - This site was located on the north bank of the Alafia River. The sites were established along the riprap shoreline on the east side of channel marker 15. OYSTER COLLECTIONS Years I & II - The only oysters in the area were attached to rock rubble and tree roots at the shell hash beach on the north bank of the river next to the phosphate plant (downstream from their dock). The bank was steep and quickly became too deep for sampling. Oysters were very sparse, and this site may not provide sufficient oysters for extended study. No geographic distinction could be made in the oyster collection sites. The three stations were contiguous to each other. Station 1 was on the west end and Station 3 was on the east end of the site. Year Iff - In Year III, there were only enough oysters for one station. This site should be dropped because of the lack of oysters. There were not likely to be other sources for oysters in the Hillsborough area, since this was the best we could locate in Year I. Years I-V, V, VI &. VII - The site was not sampled during these years. Year VIII - Oysters were collected at the station described in Year III. Oysters were numerous but small. SEDIM]!'qT COLLECTIONS Year I - Sediments of fine texture in close proximity to and representative of the site were not possible. Therefore, a site was selected approximately 0.5 miles east. Station 1 was between the boat launch and oyster site. Station 2 was from the boat basin across the river from the boat launch. Station 3 from upstream past the railroad bridge to the south side of the river in front of Captain D's Marina. Years 11 & Ill' - Sediments for Years II and III were at the same sites, except that no sediments were located for Station 1. Years I-V, V, VI, VII, & VIII - Sediments were not sampled during these years. 489 SAMPUNGMETHOD Oysters - hand Sediment - box core WATER DEPTH - subtidal, 0.6 meters POSSIBLE CONTAMINANTS - Obvious sources of contamination included the phosphate plant which was directly adjacent to the oyster collection site. In the case of two sediment samples, the boat basin/marinas were sources of contamination.

SrIE NLIMBER 46 DESIGNATORn TBCB SITE - COCKROACH BAY, TAMPA BAY FL NONaNAL srm CENTER - 27040.55'N 82030.56W LOCATED ON NOS CHART # - 11414 SITE ACCESS - The site is accessed by driving to Highway 41 and taking the Cockroach Bay Road to the west. The launch ramp is at the end of the road. Shallow draft boats with tilt motors are required. Access to the site requires winding around many small islands to the open bay to the east. Upon entering the open bay, proceed east to a very small island (mostly subtidal) near the southeast shore. SITE DESCRJIPTION - The site was located on an exposed reef on the south side of Cockroach Bay. Oysters were collected by hand from the subtidal portions of the reef. Neither the sediments or oyster collection stations could be differentiated geographically around the small island. All were composites of random samples from around the island. OYSTER COLLECTIONS Year I - Oysters were collected from an exposed reef on the south side of the bay. Station 1 was on the reef which is 1951 from the tall radio tower. Station 2 was along mangrove roots -100 m east of Station 1. Station 3 was -100 m east of Station 1 and 30 m north of Station 2. Years II, III, IV, V, V1, V11, & VIII - In these years, all stations were taken from the same very small reef in the back (south side) of Cockroach Bay. No station distinctions could be made due to the small area from which oysters were available. However, Cockroach Bay has many other sites suitable for oyster collection, both from the roots of mangroves and other reefs nearer the mouth of the bay. SEDEVIENT COLLECTIONS Years 1, 11, & III - Sediments were found in isolated pockets around this reef and were limited to the extreme upper layer. Years IV& V - No sediments were sampled during these years. Year V1- - Sediments (NIST) were collected from around the small island where the oysters were collected. Years VII & VIII - No sediments were sampled these years. 495 SAMPLINGMETHOD Oysters - hand Sediment - Sediments were sampled by hand with the teflon scoop, and required compositing samples from many scoops in different pockets to acquire sufficient material. WATER DEPTH - intertidal, 0 to 0.6 meters POSSIBLE CONTAMINANTS - There were no obvious sources of contamination in this very secluded site, although the surrounding area appeared to be vegetable and fruit farms.

The site is located on the south end of the Davis Islands, adjacent to the Peter 0. Knight airport and the Davis Islands Yacht Club. To reach this site from St. Petersburg, take 1-275 east and take exit 24, go south on Armenia to Swann Ave., then east to join Bayshore Blvd. Cross the bridge to the Davis Islands. Stay on west Davis Blvd. and then exit right on Airport to Marinique which follows the seawall. SITE DESCRIPTION - The site was not established and sampled until Year IV. Oysters were intertidal and were attached to the rocks of the jetty. The sampling site was located along the seawall and jetties. OYSTER COLLECTIONS Years IV, V, V1, VII, & VIII - Station 1 was located along the seawall beginning at the junction of the seawall and jetty on the east side of the jetty. Station 2 was at the bay end of the jetty, and Station 3 was on the west side of the jetty beginning at the seawall. SEDDIENT COLLECTIONS Years I-V & V - Suitable fine grained sediments were difficult to obtain near the site because the bottom was mostly sand. Isolated pockets of fine black muds with some sand were located along the seawall some distance from the oysters sites. Station 1 was about midway down the seawall to the the east, and was sampled by boxcore from the seawall. Station 3 was about 200 m to the west of the seawall/jetty junction, at the first joint in the concrete wall (from the west). Station 2 sediments were from the far eastern end of the seawall, at the comer closest to the airport terminal building. Year VI, VII, & VIII - No sediments were sampled these years.

Proceed down the canal, turn left and enter the bay. Join the channel markers and proceed to Bird Island After the second year, the launch site was moved to the public ramp at Red Fish Point in Ft. Meyers. To reach the site proceed down the Calooshatchee River along the ICWW past Big Shell Island. Turn north at channel marker 2 and 2A. This will take you to the west of Bird Island. An alternate launch site is at the Punta Rassa Ramp. SITE DESCRIPTION - The site was located in San Carlos Bay in the Matlacha Pass National Wildlife Refuge. The site was on a reef which was directly north of Bird Island and northeast of Merwin Key. Oysters were plentiful on the subtidal portions of the reef and could be collected either by hand or with tongs. OYSTER COLLECUONS Year I - Collections were made on the submerged reef approximately 150 m from Bird Island. Bearings to locate Station 1 were 305' from Bird Island, 325' from the end of large bridge, and 70' from the north end of Merwin Key. Station 2 was 250 m north of Bird Island at 210' and, 325' from the large bridge, and 60' from the north end of Merwin Key. Station 3 was about 200 m from Bird Island at 290', 325' from the bridge, and 70' from the north end of Merwin Key. Year II - Year II stations were in approximately the same locations. Station 1 was on the east side of Bird Island. Station 2 was north of Bird Island, and Station 3 was on the west side of Bird Island. Years III & rV - Years III and IV oyster stations were collected on the large reef north of Bird Island. Bearing to Bird Island were 110' and 130' to the high rise condo. Year V & VI - Oysters were collected approximately 500 m northwest of Bird Island at the second reef. This was the same general location as last year. Station 1 was on the east end of the reef, Station 2 was in the middle 100 m west of #1, and Station 3 was on the west end of the reef 150 m from the last station. Years V11- & V111 - The same stations described for Year V were sampled these years. 519 SEDIMENTCOLLECTIONS Year I - Sediments were collected adjacent to the oyster stations. No fine sediments were found anywhere near the oyster site. Year 11 - Sediments were sampled west of Bird Island -50-100 m from the oyster Station 3 (Station 1) and then again 200 m farther west (Station 2). These sediments were silty sand at best and contained significant amounts of sea grasses. The third sediment was collected at the mouth of the dredged channel which led to the boat launch. This site was several miles from Bird Island and about 0.5-1 mile from the boatlaunch. Year III - Sediments were collected approximately 30 m south of each oyster station. Years.. JV, V, VT V11, & VIII - Sediments were not sampled during these years. SAMPLINGMETHOD Oysters - tongs and by hand Sediment - box core WATER DEPTH - intertidal, 0 to 0.8 meters POSSIBLE CONTAMINANTS - There were no obvious sources of contamination at the Bird Island site. The site was in the open in a large bay. Station 3 sediments would not be considered representative of contaminant exposure at the oyster site. However, it was the only source of sediments which clearly met the size criteria, and the sediments would have been subject to contamination from residential and recreational boating areas which surrounded the canal.

It is accessible almost directly from the interstate via the exit for Marco Island. Proceed south on Highway 951 to Rattlesnake Hammock Road (Highway 864). Go across Highway 41 to Thommason Road and proceed to the end of the road at Bayview Park. Proceed by boat north from the park up the channel to channel marker 24. SITE DESCRIMON - The oyster reefs were located to the east and adjacent to channel marker 24. The old reefs were primarily consolidated and cemented old shell fragments. OYSTER COLLECTIONS Year I - Year I oysters were collected by hand. Station 1 was at a reef in a residential area with bearing of 185' to channel marker 24; 268' to channel marker 26. Station 1 was at the first reef adjacent to channel marker "Red 24". Station 2 was at the second reef with bearing of 172' to channel marker 22; 298' to channel marker 24. Station 3 was 100 m east of Station 2 at the small reef with a tree. Year II - The oysters during Year II were collected with tongs from the subtidal portions of the reef. Stations were not differentiated, but rather were composites of randomly collected oysters around the small, mostly dead reef. Year III - Year III oysters were collected in the same area but the stations were not distinguished. Years IV, V, V1, VII, & VIII - The site was the same as sampled previously, a submerged reef adjacent to channel marker 24. Station 1 was the submerged reef with the single mangrove tree growing on it. Station 2 was on the east side of the reef; Station 3 was sampled from clumps of oysters by the point to the east of the Station 2. SEDBUMW COLLEMONS Year I - Sediments from the area were almost non-existent, due to the nature of the consolidated shell bottom. Fine sediments were located only in very small isolated pockets that were found by chance and in boating channels that were dredged to the homesites. Year I sediments were collected along the shore east of the respective oyster stations. 531 Year Il - Sediment Station 1 was among the oyster stations. Sediment Station 2 was north of the oyster site in to the channel east and north of channel marker 26 & 27 (channel identified as Tarpon Road and Kingfisher Road). Sediment #3 was from the entrance to the boat basin at the launch ramp in Bayland Park. Years III, IV, & V - Sediments were located in the same areas as sampled in Year II. Years V1, VII, & VIII - No sediments were sampled these years. SAMPLING METHOD Oysters - tongs and by hand Sediment - box core WATER DEPTH - intertidal, 0.2 to 1 meter POSSIBLE CONTAMINANTS - Sources of contamination would be from very heavy recreational boating and dense residential development along and farther upstream on the waterfront.

The sediment collection site must be accessed by a boat. SITE DESCRIPTION - This site was established in Year VI. There were no oysters present but an alternate bivalve, the smooth-edge jewel box Whama sinuosa) of the family Chamidae, was collected for analysis. The bivalves 'were attached to the edge of the vertical face of a hard carbonate wall which is on the northeast side of a U shaped cove. OYSTER COLLECTIONS Year VI - All three stations were collected along the carbonate wall. Station 1 was in the center of the northeast shoreline. Station 2 was seaward (west) of Station 1. Station 3 was to the inside of the cove toward the road. The site was accessible from the shore and was best sampled using a mask and snorkle. Year VII - The same station were collected again this year. SEDEMENT COLLECTIONS Years VI - Sediments were collected along the mangrove shoreline east of the bivalve sites at latitude 24'40.17'N and longitude 81'15.90'W. The site could only be reached by boat traveling through shallow water. This was 0.65 mi east of the bivalve collection sites at the first point of land extending into the bay. Station 1 was at the point and Station 2 was 100 m to the east. Station 3 was 100 m to the west. Sediments at the site were primarily detrital material (mostly sea grasses) overlaying fine carbonate sand. After removing the overburden of decomposing organic material to get to the oozy carbonate/detrital mixture which comprised the "surficial sediment", sediments were obtained at a water depth of 0.2 m. Years V11 - Sediments were not sampled this year.

A boat and operator is available for rent in the town of Boqueron. To reach the site travel from the boat dock in Boqueron across Bahia de Boqueron (Boqueron Bay) on a course of 150' to the entrance of a smaller bay. Pass through mouth of the unnamed bay, turn to a heading of 50', and proceed to the east side of the bay. All three stations are located in the small bay system on the south side of Boqueron Bay SITE DESCRIPTION - Station 1 was located along the east shoreline across from the marine police boat dock (295* back to the dock). Station 2 was located on the north side of the small island at the near the mouth of the bay. The island was located south of a small channel running to the west the and west of the main channel which runs to the southeast. Landmarks from the site were the Boqueron pier (55') and the beach cottages (90'). Station 3 was further west down the channel at the end of the cove. There were no visible reference landmarks. OYSTER COLLECTIONS Year VII & V7'11'- Oysters at all three stations were collected from the roots of red mangrove trees. Many dead oysters were found interspersed with the live oysters, presumably from recent fresh water inflow. Stations are described in the site description section. SEDIMENT COLLECTIONS Year VII - Sediments were located with the oysters and were collected among the mangrove roots in 0.1 to 1 m of water. Sediments were soft anaerobic black mud over hard reddish brown clay. Year V111 - No sediments were collected this year.

SrIE NUMBER 88 DESIGNATOR - PRBJ SITE - BAHIA DE JOBOS, PUERTO RICO PR NOMINAL SITE CENTER - 17056.33'N 66010.95V LOCATED ON NOS CHART # - 25677 SITE ACCESS - This site is located in the east end of Bahia de Jobos (Jobos Bay) and can only be reached by boat. There are no boats for lease in the area so arrangements must be made with a local fisherman. To reach the boat launch area travel from Jobos by automobile on Highway 7710 toward Pozuelo, go to the second small bay area where boat are anchored. By boat go through the mangroves into the bay and turn east. Proceed to the east end of the bay to the inlet into Laguna de las Mareas. SITE DESCRIPTION - All three stations were located at the east end of Bahia de Jobos. Station 1 was approximately 100 m west of the inlet into Laguna de las Mareas on the south shoreline. Station 2 was at the inlet into Laguna de las Mareas. Station 3 was 100 m north of the inlet in a small cove. An obvious landmark is the electric generation station at the opposite end of the bay near Aguirre. OYSTER COLLEC11ONS Years V11 & WI1 - Oysters were collected at the stations described in the site descriptions. Oysters at all three stations were found on the roots ofred mangrove trees. Oysters were not abundant. SEDIMENT COLLECTIONS Year V11'- Sediments sampling stations were collocated with the oysters in 1 to 2 m of water and were collected within 2 to 3 m of the edge of the mangrove roots. Station 1 sediments were fine grain black silt with some shell hash. Station 2 sediments were fine grained black silty sand. Sediments from Station 3 were fine grained black silt. Turtle and manatee grass was abundant throughout the bay-starting near the edge of the mangrove roots. Year VIII - No sediments were collected this year. SAMPLINGMETHOD Oysters - hand Sediment - box corer WATER DEPTH - intertidal, 0.1 to 0.2 meter POSSIBLE CONTAMINANTS - There were no obvious sources of contamination. Contamination is possible from the opposite end of the bay from the power generation plant. The fisherman who took us to the site 567 said that there had been a mercury spill in the bay, but did not remember when.
