The Flower Garden Banks, lying more than one hundred miles offshore Texas and Louisiana in the Gulf of Mexico, have been nominated as a candidate site for marine sanctuary designation by Texas State Senator A.R. Schwartz in conjunction with the Texas Coastal and Marine Council. The Banks are biologically unique and important. They contain not only the northwestern most living reefs on the Gulf of Mexico Outer Continental Shelf, but also many important habitats for unusual marine organisms. Included in these habitats is the East Flower Garden Brine Seep System, appropriate for study because of its (1) unique physical, chemical, and biological systems; (2) the extreme fragility of the system; and (3) the importance of the systems in general for science and in particular for the understanding of the evolution of benthic community structure. The National Oceanic and Atmospheric Administration, Office of Coastal Zone Management, in cooperation with scientists from Texas A & M University (TAMU) and Harbor Branch Foundation, Inc. (HBF), will sample in the brine seep and adjacent canyon and hard-bottom community resources and equipment provided by HBF. This manual presents the operations plan for this resource sampling survey. OFFICE OF COASTAL ZONE MANAGEMENT The National Oceanic and Atmospheric Administration (NOAA), Office of Coastal Zone Management (OCZM) was established to administer the Coastal Zone Management Act of 1972 (P.L. 92-583). In addition to this responsibility, the Secretary of Commerce delegated the authority to OCZM to administer Title III of the Marine Protection, Research and Sanctuaries Act of 1972 (P.L. 92-532). The authority granted under Title III is for the purpose of setting forth the procedure by which areas may be nominated as marine sanctuaries and the concepts, policies, and procedures for the processing of nominations as well as for the selection, designation, and operation of a marine sanctuary. Through its desire to undertake an active role in management and research in the proposed East and West Flower Gardens Marine Sanctuary, OCZM is acting cooperatively with TAMU and HBF in planning, preparation, and execution of this deepwater resource survey. As project manager and coordinator, OCZM is providing technical personnel responsible for designing and executing the project, contacting the necessary outside scientific experts and is funding part of their equipment shipping and personnel travel expenses. TEXAS A & M UNIVERSITY . The University's College of Geoscience's Department of Oceanography is involved in oceanographic research, including surveying and sampling of unusual marine biotic communities. The Department is providing technical personnel who are responsible for developing the scientific plan for the mission, preparing and analyzing all samples collected, constructing or making available any supplies or equipment needed for scientific research, and for writing the final cruise and scientific report. HARBOR BRANCH FOUNDATION, INC. The Harbor Branch Foundation, Inc. (HBF), is a not-for-profit organization established in 1970 primarily for research in the marine sciences and for the development of oceanographic tools and systems for undersea research. Outlined below are HBF's program objectives: 1. Accumulating and computerizing knowledge in the field of oceanology, particularly as it applies to the effects of pollution. 2. Sponsoring and engaging in scientific research and development for the purposes of making inventories and obse-rving the behavior of marine plants and animals through various stages of their life cycles in unpolluted and polluted waters. 3. Developing new engineering tools and improved safety equipment for marine and oceanographic research and operating laboratories for the furtherance of such research. v 4. Developing methods for changing the character of pollution, by eliminating the harmful effects and by utilizing the nutrients and beneficial effects. 5. Sponsoring and engaging in underwater archaeology projects through the use of new engineering tools and methods. 6. Preparing and distributing publications, research materials, lectures, and seminars which serve to disseminate knowledge of marine pl ants and animals and ocean engineering research and development. HBF is providing technical personnel, both surface and underwater vessels, and equipment to meet the operation requirements for proposed East Flower Gardens Bank Brine Seep Assessment. I. OVERVIEW OF THE OPERATION The area to be surveyed is part of the proposed East and West Flower Gardens Marine Sanctuary, located approximately 110 nautical miles (nm) southeast of Galveston, Texas, and 120 nm south of Cameron., Louisiana. The proposed sanctuary would include the waters overlaying the banks and extending to within 4 nm of the 100 m (328 ft.) isobaths of each bank, a total area of approximately 173.25 square nautical miles. Personal communication with Thomas J. Bright and Eric N. Powell (Texas A & M University) indicates the East Flower Garden (EFG) Brine Seep system (Figure 1) is biologically important for the following reasons: (1) the bacteria of the seep oxidize sulfide in high salinity water at low light' levels. Data suggest that a bacterial association, under the conditions found here, occurs rarely, if at all, anywhere else; (2) the benthic communities found downstream of the seep may exist primarily on sulfur bacteria as a food source. As such, community composition and structure are exotic and population densities are unusually high (in fact, the communities are analogous to the Galapagos Rift hydrothermal vent community in this regard--see Ballard et al., 1979); (3) one of these communities --the one associated with the white sulfur bacterial mat in the overflow canyon--is absolutely unprecedented. This community is dominated by gnathostomulids, a relatively unknown phylum restricted to sulfide system-like environments. A community dominated numerically (and possibly in biomass also) by this phylum has never been reported before, and in fact, may be unique. There is every reason to believe it is a "living fossil" community; to OF 10 40A z- 4e IP IN o _J lisfy aties near brino cn*mur*n Carbonate sand AnIlpathartons' <Z1 1-cteroPot" 4TA par furcife e.* algal nodules -04 Luti timus compnhorkus 45:1!>t dumtrlll IC.% patterned burrows Rypeoster cc5c Ilsomulon MOICAurum 0@ Choetodon sadefflarlus got Seep laroldealld Other 4 Cttromis ckh _WNIO Spondyfus americanut rv.

We have not yet consulted with a systematic expert in the group, but the large size of the organisms involved, coupled with the general knowledge of the group which we do have, leads us to believe that the species may indeed be undescribed. Thus it is clear that the biological associations found at the EFG brine seep are unusual and deserving of careful study. II. MISSION OBJECTIVE Doctors Bright and Powell of Texas A & M University, with the support of the Office of Coastal Zone Management (OCZM) will use Harbor Branch Foundation facilities and equipment, including the submersible JOHNSON-SEA-LINK (J-S-L) to undertake a series of dives to quantitatively sample marine resources in the East Flower Garden Bank Brine Seep System, near the overflow canyon and coral reef, and adjacent soft-and hard-bottom communities. J-S-L diver lock-out capabilities will be used to collect any necessary biological samples for species identification. Video tape and still photography will be used to document observations. III. MISSION PLAN A. Operating Area Figure 2 shows the project operating area. The onshore base of operations will be located at Texas A & M Marine Biomedical Institute at Galveston, Texas. The physical characteristics of the area are as follows: Depth: Operating area depths vary from 100-300 feet for observations and 100-200 feet for lock-out dives. 960 940 920 LOUISIANA Port Arthur -6meron TEXAS New Orleans Houston A Morgan Ctty Galveston 0 Freeport 2 0 Ma r a alMr-d M 29 120 NM Po O'Connor 10 0 0 Part Arans ts 00 0 0 0 28 0 PUS *Go Cristi o 0 27* Figu Port Isabel LEGEND: re 2 Locatton of-the j3r ... wnsville Flower Carden Banks.

Dr. Nat Eiseman of HBF will be conducting the required observational transect from the shallow (coral reef) area of East Flower Garden Bank to a point below the brine seep. He will also be conducting a series of lock-out dives at 100', 125, 160', 200' and at selected points around the "brine lake" and "canyon". These dives are necessary to augment the transect work. The'distribution and species of algae collected will be reported. Light meter and thermograph instruments will be deployed in the study area and recovered at the conclusion of the mission. Dr. Robert Jones of HBF will be making observations and photographic recordings of marine fishes in and around the brine seep. This will be a continuation of work begun by 9 Dr. Bright. Of special interest will be the behavior of these fishes toward the brine stream. 15 September Depart operations area * Return to Galveston to offload scientific party. R.V. Johnson returns to Link Port. 18 September R.V. Johnson arrives Link Port. C. Training Requirements No specific training will be required for this operation as HBF will be using experienced staff familiar with the equipment and procedures required for this mission. D. Routine Reports The only routine report which will be made during the mission is a scheduled call to Link Port each morning 0900 to inform HBF of the happenings of the day before and the scheduled activities of the day. Because a NOAA Representative will be on-site throughout the operation, reports will be submitted to OCZM on an as-appropriate basis, followed by a report at the end of the operation. E. Limiting Environmental Conditions Limiting environmental conditions which have a significant impact on the execution of the mission are: Sea State - The surface support vessels cannot operate in a Sea State greater than 5 as they are unable to launch or recover the J-S-L. Therefore, any time such condition arises, the operation will be halted until calmer seas prevail. The weather forcast will be monitored on Channel WX and NOAA will contact the National Weather Service to inform them of the planned mission so they may provide up-to-date information upon request. Currents- Because the operational propulsion of the J-S-L is 1.5 knots, any curents over 1.5 knots will result in review of the planned dive. Turbidity- Reduced visibility in the water could have an impact on good photographic data and limit submersible operations. 10 F. Alternative Mission Plans If the Sea State is such that the vessels cannot operate, no mission plans can be substituted as the purpose of this operation is to conduct a biological assessment which requires vessel operations. If operating days are lost due to weather, first priority will be given to TAMU for completion of their research. G.. Scientific Reports HBF will provide final reports on their algae and fish investigations by December 30, 1980. TAMU will provide NOAA with a cruise report by November 1, 1980 and a final scientific report in publishable form by August 31, 1981. IV. Organization and Personnel Figure 4 illustrates diagrammatically the organization of the participants in the operation. A. Chain of Command and Responsibilities Director, Operations and Enforcement (OCZM)- is responsible for overall program planning and coordination. He will be advised by the NOAA representative and the operations director of any event which could affect the safety of the open-sea operation.

C. Diver Description and Equipment 1. JOHNSON-SEA-LINK Lock-out Dives a. Breathing Equipment Primary Umbilical-supplied, open circuit , KMB-10 hat with communications Secondary Small Auxiliary Bai*,- out Bottle (KMB-10 only) b. Breathing Mixture Air 1200 cubic feet total-air 600 cubic feet total-02 33 Description Normally a lock-out dive from the J-S-L will consist of one tethered diver who is tended by another diver from inside the dive compartment. As the J-S-L approaches a lock-out site, the pilot positions the J-S-L on the bottom, pointing into the current at the work site, reports his depth to the support ship and requests permission to flood down. After the divers are dressed-out and report ready for lock-out, the pilot requests permission from the surface to blow down. The divers secure their 02 bleed and C02 scrubber, check "A" hatch undogged and report to the pilot standing by for blow down. Then the pilot initiates a count down over the underwater telephone and the J-S-L intercom. The diver-tender controls blow down in the diver compartment and maintains a 100' per minute descent rate. The rate of descent is monitored by. the pilot. (If necessary, the pilot can override the tender). When the diver compartment equalizes and the "A" hatch seal is broken, the pilot reports to the support ship. When the "A" hatch seal is broken the diver-tender secures the blown down, pushes "A" hatch of the manway and gives the diver a last minute check before he enters the water. 34 When the diver initially enters the water he gives the J-S-L a lift test by trying to lift it off the bottom, and makes a communica- tion check with the pilot before leaving and diver compartment. The pilot reports to the support.ship that the diver is out. The diver is continuously monitored by the pilot and observer throughout the dive. The diver's bottom time is kept by the diver-tender, pilot, and support ship. The diver's umbilical is tended throughout the dive by the diver-tender. When the diver returns to the J-S-L at the completion of his task, the diver-tender takes up the umbilical and assists the diver through the manway, lifts and dogs "A" hatch, drops "B" hatch and over pressurizes the diver compartment V-10'. The pilot reports the over-pressurization depth in the diver compartment to the support ship and requests permission to surface. The divers blow the bilge ballast tanks and the pilot commences blowing the diver ballast tanks. The pilot reports to the support ship when the ballast tanks.are blown dry. As the J-S-L leaves the bottom, the divers commence venting the diver compartment to their first stop. The venting is monitored by the pilot and observer. Venting can be controlled either from the pilot's sphere or the diver compartment. 35 2. Surface Support a. Communications will be maintained between divers and pilot during swimming excursions, via hard wire. b. Communications will be maintained during lock-out dives from diver to submersible to R/V JOHNSON. C. Should prolonged decompression or treatment be necessary following a lock-out dive, the submersible will return-to @the surface'--and.be mated to the Ncompression chamber aboard the R JO NSON. d .

Sonar System (J-S-L) The Straza Industries Model 500 CTFM (Continuous Transmission Frequency - Modulated) sonar electronic stack is mounted on the forward end of the electronics equipment rack in the center of the sphere. The training mechanism, with hydrophone and projector attached, is mounted on top of the pilot's sphere hold assembly. The high resolution sonar can detect and view underwater objects at all bearings and at ranges from 3 to 1500 yards. The system provides both audio and visual outputs and has thecapability of maintaining simultaneous contact with multiple targets and markers or transponders. C. Transponders One Straza transponder Model 7030 is attached to the support ship's underwater electronics tower and is powered by 14 VDC from the electronics control station on'the bridge. When the Straza transponder is interrogated by a signal from the submersible's sonar it transmits a pulse, shows up on,the sonar PP1 scope as a "blip" and indicates range and relative bearing to the surface ship. A second Model 7030 trans- ponder is carried on the support ship. It is battery powered and can be used as a back up or a location marker at depths to 100 feet. 44 d.' Loran C The R/V JOHNSON will use a Loran C (Two Northstar 6000's) for navigation. e. Tracking Tracking the J-S-L is accomplished with a Honeywell R57 indicator. This unit displays a signal received from a beacon mounted on J-S-L. The R57 displays two channels at one time on a bridge mounted cathode ray tube. This unit shows range and bearing and can track and display both submersibles simultaneously. 2. Undersea System a. Pingers The Straza pinger is mounted in a bracket on the after "A" frame and is turned on by a saltwater activated switch. The Helle pingeris a similar bracket on the after "A" frame and is switched on by closing a switch on the sphere electrical control panel. These pingers are tracked by the support ship with a Straza marker receiver Model 9010/MRM-503 passive tracking sonar. Accurate relative bearings out to 2500,yards on the Straza pingers are normal. 45 b.' Doppler Sonar Navigation System The Sperry SRD-101 Doppler Navigation System consists of the following major components: The transducer assembly, the electronics pressure can, the control and indication unit, and the magnesyn compass. The SRD-101 employs beams of continuous wave ultrasonic energy, directed obliquely at the ocean floor, to obtain true speed and dis- tance covered over the bottom @in the fore-aft and starboard-port direc- tions. Speed and distance are displayed on a heading-drift in- dicator, along with desired magnetic course and actual magnetic heading. d. Echo Sounder The data marine digital echo sounder is mounted on top of the sonar stack in the forward part of the pilot's sphere. Power is applied by closing a switch on the sphere electrical control panel. A Model 3023 transducer is mounted on the after bottom "A" frame. VII. Emergency Procedures A.

Cook RFD 1, Box 196 Operations Director Fort Pierce, Florida 33450 Harbor Branch Foundation, Inc. 305/465-2400 Roger W. Cook's career as an underwater specialist began while in the Navy's underwater demolition team. The use of hand-held sonar and Swimmer Propulsion Units from Navy Fleet Submarines were among his duties. Following his naval service, Mr. Cook worked for the Pacific Missile Range on Kwajelein in the Marshall Islands recovering missile wreckage and components. During this time, he was trained by representatives of Perry Submarine Builders as pilot of the PC3A sub- marine; a dry, two-man submersihle rated to 300 feet. He logged more than 70 dives in this submersible. From 1966 to 1972, Mr. Cook was employed by Ocean Systems, Inc., as Chief Pilot for the Link.-designed ,liver lock-out submersible DEEP DIVER. He logged more than 80 dives at sites ranging from Newfoundland to Europe and the Caribbean. Most of these dives were lock-out, two were saturation dives. DEEP DIVER, depth rated to 1350 feet, was used for work with the U. S. Navy under the Search and Recovery contract. This work also included use of an ADS IV (Advanced Diving System) to recover crashed aircraft and other objects in. depths greater than 200 feet. In 1972, Mr. Cook joined Perry Submarine Builders as Project Supervisor for the designing and supervision of construction, for the complete outfitting of a one-atmos- phere, 5-man personnel transfer bell . He then procured and adapted a support vessel for the PTB. He piloted 41 dives in the PTB. Since January of 1974, he has been with Harbor Branch Foundation, Inc., a not-for-profii-corporation engaged in pollution studies, ocean science and engineering research and development. As.Operations Director, he is repsonsible for planning and directing the missions of the founda- tion's research vessels, submersible support ships, and the J-S-L I and II, Harbor Branch's aluminum and acrylic submersibles. Through his supervision and training for the 4-man crafts, these submersibles are used for diver lock-out which serve the marine scientists at Harbor Branch with the capability to observe, collect living samples, photo- graph, chart and.measure features and phenomena of the undersea en- vironment heretofore not possible for surface oceanographic ships. Mr. Cook has directed more than 100 scientific cruises thus far at Harbor Branch', the most recent being a, 600' lock-out dive off the coast of Fort Pierce, Florida, the second deepest-on record from a submersible.

If voice communications are lost on the underwater telephone for fifteen minutes, the J-S-L pilot should su--face with extreme caution as soon as practicable, attempt to communicate on the way up by both voice and C.W., establish communications via FM transceiver when surfaced. 2. In the event that communications are lost on the surface and the support ship is not in sight, turn on.the flasher and attempt to communicate on FM transceiver with any station on the emergency Channel Fl (Channel 16). If you suspect that both FM transceivers are out of commission and believe the support ship to be within a two-mile radius, consider diving the J-S-L to 50 feet and attempting contact on the underwater telephone or via C.W. 3. If the J-S-L gets entangled on the bottom, commun- ications between the sphere and the dive compart- ment should be made on the sound powered phone and communications to the support ship should be held down to a minimum to conserve the battery. The underwater telephone uses power as follows: Mode Current a. Receive 1 amp. b. Transmit Near I-amp. c. Transmit Medium 8 amp. d. Transmit Far 17.5 amp. 4. Transmit time can be held to a minimum using the codes outlined in Appendix "C". 2-1 Flooding 1. Uncontrollable - It i s highly unlikely that J-S-L could encounter an uncontrollable flooding situation without having a collision with another vessel or submerged object. It is also doubtful that the diver compartment would be penetrated in a,collision. one of the main ballast tanks could be pierced and rendered almost o,--less, but the J-S-L could surface on the other tanx ,nd if necessary, the battery pod could @,e dropped. Themost vulnerable part of the J-S-L is the plexiglass sphere that could crack if it comes in contact with another hard object at a combined speed of 1.81 knots oft the surface to 4.77 knots at 1000 feet. Evidence to date shows that the hull may crack but would probably stay together and not leak due to external pressure holding it. in compression. If this was the case, the J-S-L should not attempt to surface above 100 feet. At that depth divers would rig se- curing lines to the J-S-L frame to be winched under the handling system for recovery. The action to be taken depends on the situation as follows: a. If the diver compartment has a seal and the pilot's sphere has uncontrolled flooding: (1) Blow main ballast. (2) Release the emergency buoy.. (3) Thruster up if possible. (4) If the.crack is in the lower two-thirds of the sphere, and @qater'is coming in, pressurize as necessary. (5) Blow all remaining ballast. (6) Inform the support ship and diver compartment. 7) Secure electrical power as dictated by the flooding. (8) Don emergency regulators and face masks as necessary. (9) Drop the battery as a last resort. (10) When the J-S-L arrives on the surface, stay in the submersible, turn on the flasher, communicate if possible and maintain positive buoyancy until help arrives. 2-2 b. If the pilot's sphere has a seal and the diver compartment has uncontrolled flooding: (1) Blow main ballast (use gas bank not needed for pressurization of diver compartment). (.2) Check selection of correct supply to blow and mask 5-way valves. (3) If necessary, divers should be on the re- breather or mask system. (4) Report to surface ship. (5) If flooding is rapid, pressurizing of the dive.compartment may be required. (6) Prepare to drop the battery (complete flooding of the diver compartment will require dropping the battery and blowing main ballast tank dry to achieve positive buoyancy). (7) Secure electrical power to the diver compartment. Communicate via the sound- powered phone. (8) If main ballast tanks are dry and the J-S-L is still negative, dropping the battery will produce a positive buoyancy of at least 700 lb. Switch to emergency battery and inform the surface, then drop the battery. @Ascent will be uncontrolled. c. In the event of surface collision, it is possible that one or.both main ballast tanks might be damaged as well as the pilot sphere, and dropping the battery would not provide positive buoyancy.' Once the J-S-L was on the bottom, personnel in the pilot's sphere could tranfer to the diver compartment as a last resort.- Communication with the surface would almost certainly be out and probably with the dive compartment. The procedure would depend on the pilot's assessment of damage, but would resemble the following: (1) Blow the emergency buoy. (2) Establish communications with the divers. (A written message could be held against the back of the sphere and read through the forward view- port in the diver compartment). Inform them of transfer attempt. Prepare.for pressurization. Close sphere access line hull stop in diver compartment. 2-3 (3) open air cross-connect. (4) open oxygen cross-connect. (5) Select the desired supply with the,pilot's 5-way valve and line up the emergency cross-connect manifold so the divers can pressurize using the sphere access line hull stop. (6) Pressurize the diver compartment and have a diver stand by-pilot's sphere hatch. (7) Complete flooding sphere as neccesary to allow hatch to be opened. (8) Send observer back to diver compartment with standby diver. Have diver return when "A" hatch is clear; swim back to diver compartment. (9) Have diver remove all lead ballast and all unnecessary equipment. At this point, it is conceivable if only one main ballast tank is damaged, the battery is dropped and all other tanks are dry that the J-S-L.might become slightly positive. The diver should be prepared to return quickly. (10) If the J-S-L remains on the bottom, the crew would have to use the diver compartment as an ambient pressure habitat until help arrived. With four persons and no electrical power, C02 scrubbing would.-have to be accomplished by other means. If the inhalation hoses of the rebreather masks were disconnected, two people could at least partially scrub the compartment for four. The other two could take absorbent and fold it up in any piece.of cloth and breathe through it. Emergency C02 absorbent stored in the diver compartment should last two days. 2. Controlled Flooding (leaks) - the following type leaks mrght occur anytime at any depth: a. Minor leaks due to "0" ring failure or corrosion around mechanical,.electrical, and pipe hull penetration. b. External depth gage leaks due to gage failure. c. Pneumatic lines leaks allowing water to back-up line into J-S-L compartment. Electrical penetrator burn out. 2-4 Any one of the above is cause to abort a mission. Surface as soon as possible. Pressurization of the sphere to control these leaks should not be done except when on the surface. The sphere hatch will.only hold 60 PSI.of internal differential pressure. Electrical equipment should be secured as necessary to eliminate short circuits. Fire 1. The most probable cause of a fire in the J-S-L will be an overloaded circuit due to a ground or a faulty electronic component. Prior to the fire, the submersible occupants are likely to detect an odor of smoldering insulation and/or possibly see smoke. Just prior to this or maybe simultaneously, the occupants should note the failure of a piece of equipment. The second most probable cause of a fire would be due to auto-ignition in one of the pneumatic systems. Because fire cannot be entirely ruled out, oxygen should be carefully monitored to eliminate concentration above twenty-one percent. The lowest concentration of oxygen capable of . supporting life wihout any ill effects is 16 percent. 2. Smoke and/or fire while cruising: a. In the sphere (1) Turn off circuit breakers. (2) Turn off sphere 02 flow. (3) Don emergency regulators and face masks. (4) Fight fire with extinguisher and/or water. (5) Commence surfacing. (6) Inform the support ship and diver compartment. (7) Upon reaching the surface, ventilate with He02; through the flare gun barrel as necessary. In the diver compartment (1) Secure the 02 bleed. (2) Inform the sphere. (3) Don emergency rebreather or masks, or Kirby Morgan masks. 2-5 (4) Fight fire with extinguishers and/or water. (51 Sphere: (a) Secure diver power and oxygen to the diver compartment. (b) Commence surfacing. (c) Inform the support ship. (d When the J-S-L reaches the surface, have the divers ventilate.the diver compartment with-He02. 3. Smoke and/or fire while a diver is locked-out: a. In the sphere (1) Secure the oxygen bleed. (21 Call the diver back. (3) Turn off circuit breakers. (4) Don emergency regulators an'd face masks. (5) Fight fire with extinguishers and/or water. (6) Man the sound-powered ph(@ne. (7) Commence surfacing as soon as the diver compartment is over pressurized. (8) Inform the support ship if possible. (9) Upon reaching the surface, ventilate with He02 through the flare gun barrel. b. in the diver compartment (1) Inform the sphere. (2) Don emergency rebreather or spare Kirby Morgan mask and enter the. water in the manway. (3) Fight the fire with water or extinguisher. (4) Blow down with HeOi. (5) Sphere: (a) Alert the diver in the water, (b) Secure oxygen to diver compartment. 2-6 (c) Inform the support ship. (d) As soon as the smoke is cleared, get the divers back inside and commence surfacing. Ruptured Pressure Line 1. Internal - A ruptured pressure line or leaking fitting on any one of the pneumatic systems inside the submersible can easily be detected by the sudden change in the noise level and/or the' increase in compartment pressure. A leak in the oxygen system can also be detected by monitoring the P02 meters. The faulty system should be iso- lated.immediately by securing the appropriate hull stop valve. In most cases, it will be possible to bypass or repair the malfunction while submerged. A report should be passed to the support ship. a. Ballast tank pressurization lines - A ruptured or leaking ballast tank pressurization line would be detected by observing bubbles while pressurizing the ballast tank. Since the variable ballast tanks have a common pressuri- zation line, a break in this line would disable both. Allother ballast tanks have separate pressurization lines and a broken line can easily be isolated by securing the appropriate blow valve. The main ballast tanks also can be pressur- ized from the diver c6mpartment. The mission should normally be aborted and the pilot should request permission to surface as soon as practicable after detecting a faulty ballast tank pressurization line. b. Gas supply lines A rupture in one of the gas supply lines.will be detected by loss of pressure on the appropriate'gage and/or bubbles in the water. In the event a gas supply line is broken, secure the appropriate hull stop valve and realign valves as necessary to keep the J-S-L operational. Request permission to surface as soon as practicable. @ntrapment 1. Your best insurance for survival. in case of entrap- ment is the pre-mis*sion planning and the thoroughness with which the pre-launch check was made; one item overlooked could make the difference between life and death. 2-7 2. Entrapment of J-S-L means that it is being physically'held in place, such as getting caught in.a crevasse, being stuck in the mud, entangled in plant life, or entangled in sub- merged debris, such As cables or fishnets. More than likely, the J-S-L could be worked out of all these situations by using the thrusters and blowing all ballast tanks, except entanglement in submerged debris. 3. As long as either thp diver compartment or pilot's sphere is dry, the J-S-L has enough positive buoyancy to surface if it is not anchored to the bottom in some way. If, by chance, the diver compartment was flooded, the battery pod would have to be dropped and the main ballast tanks blown to gain enough positive buoyancy to surface. 4. If the J-S-L is entrapped and cannot break loose by normal means, and neither the pilot or divers can clearly determine that a lock-out diver could free the submersible, the J-S-L would blow the buoy, vent its tanks, secure.all unnecessary equip- ment to conserve power, and await rescue. A lock- out dive would be conducted only as a last resort in the event that the divers were unable to clear the obstruction. S. if the divers are unable to free the J-S-L, bring them back in and shut both "A" and "B" hatches. Do not over pressurize. Keep calm, conserve power, monitor your PO and PC02 meters, and maintain com- munication on t@e sound-powered phone. NOTE: Anytime the J-S-L is launched, it has gas onboard for a lock-out to maximum mission depth plus adequate dive gear and rescue tools aboard. There is always at least one qualified J-S-L lock-out diver in the diver compartment. 2-8 DOC Facility The following is a detailed breakdown of the D.O.C. volumes and gas storage capatities: Entrance Lock 67.9 S.C.F.

BAKER Administrative (PURA 787M)CARBON DI0XIDE REM0VAL SYSTEMS Units in this series are assembled from three main camponents; an outer sealed case, a refillable dessicant canister, and a power unit. The canister and power unit are mounted in tandem 'within the exterior case. In operation the turbine end of the Power unit exhausts air from inside the case, forcing it out through coaxial ducting surroun ding the power unit. As the gas within the case is exhausted,a pressure differential. is established., causing external air to flow through the intake end of the dessicant canister. This air is scrubbed or purified by chemical compounds which retrieve and retain carbon dioxide, and pass other gases in the breathing mixture to be reused indefinitely. Operating electric motors of any type in environments with high partial pressures of oxygen or flammable gases is extremely hazardous. Commutator-type motors with sparking brushes are obviously dangerous- Induction motors, though brushless, are also dangerous since short circuits can develop in field and rotor coils to trigger an explosion- `Inverter-type motors share the same deficiencies. The PURA 787M completely isolates the motor, wiring system and other electrical components from contact with the environmental atmosphere by installing these inside a heavy walled pressure vessel. To eliminate the danger of seal wear on a rotating motor shaft, a magnetic coupling connects the motor with the external dual turbine. There is no direct mechanical connection between motor and turbine; magnetic lines of force pass through solid stainless steel, estab- lishing a high torque interlock. All dynamic sealing is eliminated. Other static sealed closures are dual. sealed with two types of O-ring glands for safety. Each unit is environmentall leak checked at pressure stages from 1 to 1500 PSIG and certified. Motor heat is dissipated through a heat sink system. There is no direct air flow through the motor All bearins in contact with high pressure environmental oxygen are specially treated and compatible with any breathing MIX- tures. 2-16 0 ELECTRICAL CONNECTIONS - 787M9 Series scrubbers operate on 24 to 6 volts, AC or DC. The motor is a universal type and is unidirectional; it cannot be externally reversed by inter- changing leads. Connect two wires from hull pentrator to a suitable power source. Make certain that all connections are mechanically tight. Tie down all loose cable with suitable straps or clamps to guard against accidental snagging Use only approved explosion-proof switches in pressurized environ- ments DO NOT make or break Pressure-exposed connections in oxygen atmospheres. GROUND TERMINAL - Secure a heavy gauge wire to the ground ter- minal (located at the exhaust end of the unit next- to the hull penetrator) and connect it to an adequate ground; (metal side- wall of a' hyperbaric chamber). CONNECT GROUND CABLE BEFORE 0PERATING UNIT. MOUNTNG- Scrubbers will operate in any attitude. Preferred mounting position is vertical:, against a sidewall near *floor level.

Prepacks are NOT recommended in -high partial-pressure oxygen atmospheres because of their flamability. Gas flow through prepacks is not as efficient as through stock stainless steel refillable canister.

Page I 2-17 0 LOADING - The unit is prepared for use by filling the desic- cant canister with a carbon dioxide ab-sorbent chemical. Fill prior to each use with fresh, dry desiccant. DO NOT OMIT this s procedure- Sodasorb is recommended, although the canister may be charged with any approved desiccant. Remove the canister from within the case by twisting the five securing snap-locks to release i the loading cover. Remove the cover exposing the canisiter. Lift the canister straight out with the, wire bail and then free the canister top from the three locking; bayonet pins. Fill the cylinder carefully with desiccant. While filling, tap the canister firmly an "th e bottom with the palm of the hand to settle the granular chem- ical.. If the unit. is operated in a vertical position, the desiccant. will settle. firmly without "channeling" If oper- ated in a horizontal attitude, 'the canister must' be packed tightly with great care to avoid settling, which might cause a void along the side of the. cylinder through which. intake gas would flow freely without passing through the desiccant. Such channeling is extremely dangerous since the carbon dioxide is not retained. Inspect the bottom gasket (intake end) on which the -canister seats for dirt or dust and clean carefully.Clean the mating machined bronze surface of the canister. Replace the top screen canister cover, locking it in place on the bayonet pins. Lower the canister into position within the unit. Clean the top machined surface of the exterior case around the- five snap-locks.' Check the loading cover gasket for-dust and wipe clean. Position the loading cover over. the snap-locks, and push it straight down forcing the attached bronze- compres- sion. ring against the canister. Pull upon the snap-locks 'with a slight outward force and twist them into position to lock the cover securely in place. Check the loading cover gasket carefully f or proper positioning, especially along its straight edge where the actual sealing area 'is narrow. It 'is important that the exterior case is maintained gas tight, so that the air fldw is through desiccant canister only. If the case -is punctured., patch' immediately or carbon dioxide removal will be severely impaired (See Maintenance). Page 2 2q-18 8. 7.

OPERATION INSTRUCTIONS FOR REMOTE OXYGEN MONITOR AND RECORDER (DEVELED FOR THE HARBOR BRANCH FOUNDATION) GENERAL This monitor was developed to fill a need for a four (4) station hyperbaric oxygen analyzer with adjustable high and low alarms. Integrated circuit techniques have been employed in its construction, insuring many years of reliable service, while enabling a complexity impossible just a few years ago. The unit will operate over a wide temperature range (32oF to 1050 F) and will enable the operator to. maintain precise control over the oxygen partial pressure in the diver decompression chamber. DESCRIPTION AND CONTROLS This monitor consists of a four (4) station oxygen monitor. with adjustable high and low alarms in a brushed aluminum rack configuration. In addition, stations #1 & #2 are backed up by Rustrak type recorders; these recorders produce a permanent record of the oxygen level for later evaluation. Stations #1 & #2 have a full scale sensitivity of 2 Atm. Abs. Stations #3 & #4 have a full scale sensitivity of .4 Atm. Abs. Each station has a sensor select switch, sensor calibrate controls, alarm adjust switch, high and low alarm set controls, recessed taut band suspension display and an alarm light emiting diode. In addition, common to all stations, the front panel contains a power disconnect switch, an audio alarm disconnect switch, a sonalert type audio alarm and push to. reset circuit breakers for batteries and line. All stations share a common power supply with a battery back up. 2-25 REFERENCE 4 PRIMARY LIFE SUPPORT EQUIPMENT PYROTECTOR AUTOMATED FIRESUPPRESSION SYSTEM. 2-26 SECTION I DESCRIPTION 1.1 INTRODUCTION This technical manual provides information on the Optical Fire Detection and Extinguishing System Components manufactured by Pyratector, Incorporated, Hingham, Massachusetts for installation in HBF's shipboard decompression facility. -1.2 GENERAL DESCRIPTION The Fire Detection and Extinguishing System is an integrated automatic detection, warning and extinguishing system utilizing high speed optical detectors, signal conditioning amplifiers, control panel and Hilan 1301 extinguisher assemblies which can be activated at the control panel by operation of electrical switches or manually at the site of the solenoid valve assembly.

The actions taken as a result or the measured oxygen and combustible gas levels must be in strict accordance with: Company and Government regulations. The instrument should not be used to reasure combustible gas in an atmospheres either oxygen deficient or containing more than 25% oxygen by volume. GENERAL The Biomarina Combustible. Gas/Oxygen Monitor provides a simple method of determining oxygen concantracticus and combustible gas levels in any environment. The instrument may be used for both spot checks and continous monitoring with alarms. When used as a monitor, oxygen level and battary voltage are monitored continuously and Combustible gas level is checked automatically every three minutes. This "sampled data" approach allows forty hours continuous operation before battery recharging. Easily portable and simple to operate, the Monitor is automatically temperature compasated over its full operating range of 5 F to 110 F. The Monitor requires ingrequent calibration and performs accurately in high humidity environments. While methane is the calibration standard for the cumbustible gas monitor, other combustible gases will be detected. If desired, combustible gases other than methane may be used for calibration. CAUTIONS 1. The battary must be tested before monitor is used. 2. In combustible gas concentractions above 100% LEL, the instrument will give incorrect reading. If it is suspected that concentrations higher 2-32 APPENDIX 3 Notification of Coast Guard and Navy Rescue Organizations Notification of Coast Guard and Navy Rescue Organizations Prior to commencement of the at-sea portion of the project, Harbor Branch Foundation, Inc. shall notify the Coast Guard in accordance with Coast Guard Notice 3130, by completing and submitting USCG Form 4790 (8-71), "Summary of Planned Submersible Operations." This form will.be sent to Commander, 8th Coast Guard District, New Orleanse The Commander of the 8th Coast Guard District will notify appropriate Navy authorities of the impending operation, and will issue a warning to mariners giving location and time of operations in order to minimize interferences during the operations. If the submersible should be unable to surface, the support ship shall radio a MAYDAY message to the Coast Guard on 2182 KHZ, and other emergency circuits .as may be avatlable. The Coast Guard Rescue Coordination Center (New Orleans) may be reached using a telephone call via the marine operator 504/589-6225. Upon receipt of the MAYDAY message, the Coast Guard will proceedin accordance with Commandant Instruction 3130.7A of 5 December 1975. If Navy assistance is appropriate, the Coast Guard will so request by calling,the Navy Department Duty Captain at 202/695-0231. The Navy Duty Captain will take action in accordance with OPNAV Instruction 3130.4A of 29 October 1973. Applicable portions of Coast Guard Instruction 3130.7D and OPNAV Instruction 3130.4A are presented hereinafter: 3-1 0 DEPARTMENT OF TRANSPORTATION MAILING ADDRESS U.S. COAST GUARD (G-M-2/USP/83) UNITED STATES COAST GUARD 400 SEVENTH STREET SW. WASHINGTON. D.C 30590 PHONE (202) 426-2307 PLANNING & SPECIAL PROJECT STAFF C0MDTINST 3130.7D 5 DEC 1975 DEC 17 1975 C0MMANDANT INSTRUCTION 3130 .7D Subj: Operations involving Civilian Submersibles I. Purpose. This Instruction provides procedures to be followed by the Coast Guard with respect to operations involving civilian submer- sibles. 2. Cancellation. Commadant Instruction 3130.7C CH-1 is -cancelled. 3. Discussion. a. The Coast Guard's search and rescue responsibilities extend to vessels operating under, as well as on, the surface of the sea. These responsibilities therefore include the small number of civilian submersibles which operate in or near U.S. waters an scientific, indus- trial or other missions. The safety record of these submersibles has been good, but the few accidents have demonstrated both the difficulty of rescue and the potential for public interest. The Coast Guard has no special undersea search and rescue equipment to assist a submersible unable to surface and must discharge its responsibility by requesting suitable equipment be brought to the scene. Equipment is available which could effect a rescue in most situations, but frequently information on the location and status of the equipment is not available. The primary source of expertise and equipment is, the U.S. Navy, and procedures have been established to permit utilization of Navy resources in the event of a civilian submersible SAR incident. A single point of contact has been established, as the Navy can provide not only fleet resources but specialized experimental equipment located at laboratories, and also civilian specialists retained contract for undersea salvage. The point of contact is the Navy Department Duty Captain at the Pentagon, as described in 0PNAVINST 3130.4, enclosure (1). When the Navy has responded and assumed the role of SAR Mission Coordinator, the Coast Guard role be- comes one of support. Until that time the Coast Guard must respond with its own resources and whatever local civilian or government help is available. b. Submersible operations present another problem. This is one of interference with Navy operations. To enable the Navy to reduce this possibility, to reduce the chance of classifying a civilian submesible, as an unknown submerged vessel necessitating investigation, and to aid in prompt SAR assistance the Commandant has established a voluntary 3-2 COMDTINST 3130,7D 5 DEC 1975 reporting system through which pertinent information can be relayed to concerned parties. The Commandant (G-M-2/USP/83) monitors submersible activity and advises known submersible operators of the reporting system and the procedure for requesting assistance if needed. c. There is no mutual assistance plan, formal or informal, in effect among the submersible operators. Most operators, however, could be expected to be willing to assist in the rescue of a distressed sub- mersible. 4. Action. a. Commandant (G-M-2/USP/83) (1) Info= all known submersible operators and owners in the 'United States of the voluntary reporting system. Enclosure (2) is a copy of the notice used for this purpose. (2) Maintain liaison with the Navy and other organizations to provide coordinated planning for submersible emergencies. (3) Distribute periodic reports on the status of U.S. sub- mersibles to all District Commanders. Coordinate the distribution of appropriate informational material to District Commanders (RCC!s). The following publications are currently distributed automatically: Deep Submergence Systems Summary and Characteristics Manual: Published and revised annually by Commander Submarine Develop- mant Group One as COMSUBDEVGRU ONE INSTRUCTION 5450.1 and contains characteristics of U.S. military and civilian submersibles, unmanned undersea systems, and habitats. An Inventory of Navy Laboratory R&D Equipment Available for Emergency Undersea Operations: Published by and revised annually by Naval Undersea Center, San Diego as NUC AP-2. b. District Commanders (1) On receipt of information on planned submersible operations disseminate this information by message as described in enclosure (3). Issue a Notice to Mariners as appropriate giving the location and time(s) of operations to minimize interference during the operations. (2) In the event that a specific request for assistance to a civilian submersible is received: COMDTINST 3130.7D 5 DEC 1975 (a) Obtain Navy assistance, if appropriate,by calling the Navy Department Duey Captain in the Pentagon at the following phone number, notifying him of the situation: COMMERCIAL (202) 693-0231 .AUTOVON 22-50231 If appropriate request implementation of SUBMISS/SUBSUNK for civilian submersibles in accordance with OPNAV INSTRUCTION 3130.4, and the usN ADDENDUM to NWP 37(B). Send a follow-up message in the format of enclosure (4) to confirm request. (b) Respond with appropriate Coast Guard resources, such as On- Scene Commander rescue platform (buoy tender), traffic control, communi- cations, an logistics. (c) Ascertain if there are any other civilian submersibles available; request that they assist the distressed sub. (d) Coordinate the response as SAR Mission Coordinator (SMC) until the Navy assumes this responsibility. Continue to provide any assistance requested after the Navy assumes SMC. Ensure that the AREA COMMANDER, and the COMMANDANT are kept informed of the progress of the rescue both before and after the Navy assumes SMC. (e) Until the Navy assumes SMC (and in case the Navy is unable to assume SMC) obtain advice from Headquarters Flag Plot and make use of best available military and civilian resources. A brief guide to RCC controllers in handling submersible SAR incidents is printed by and available from the National Search and Rescue School, Governors Island, New York. (f) Prepare a SAR Case Study in addition to the normal assistance report. (5) Availability of Forms. a.

Deep submersibles have the following common character- istics: a. Life support systems capacity varies and is gen- erally less than 24 hours. Some exceptions are the Submarine NR-1 and USS.DOLPHIN. b. The hatches on the deep submersibles are normally not compatible with the Deep Submergence Rescue Vehicles (DSRVs) and Submarine Rescue Chambers (SRCs) used for submarine rescue. c. Deep submersibles are usually not designed for escape using buoyant ascent. Again the deep diving sub- marines USS DOLPHIN and Submarine XR-1 are exceptions. d. At the present time the only feasible method of saving the lives of an untethered manned non-combatant deep submersible crew would be to salvage the vessel. Enclosure 4. If the J-S-L I is entrapped and cannot gain it's freedom by blowing all ballast and thrustering, time should not he wasted waiting on help from the surface. Turn off all unnecessary electrical equipment to conserve power for your scrubbers and communications. Vent off ballast tank, blow down and diver compartment and lock-out a diver to survey the situation. Once you know what your problem is you can figure a way out. This information will be invaluable to the people on the surface preparing for your rescue. Be sure to keep accurate records on the divers' depth and time. Keep the support ship informed of all measures taken. 5. In the event. that J-S-L l divers are unable to free the J-S-L 1,bring them back in and shut both "A" and "B" hatches. Do not over pressurize. Release your emergency location buoy, keep calm, conserve mower, monitor your P02 and PCO2 meters, and maintain communication on the sound powered phone. NOME: Anytime the J-S-L I is launched it has gas onboard for a lock-out to maximum mission depth plus adequate dive gear and rescue tools aboard. There is always at least one qualified J-S-L 1 lock-out diver in the diver compartment. 3-14 Ell CLOmx, (2) Co CM-0TINST 3130.70 0 E C 197 S ome 0A.R3050 L)FPAR*r.':'N'T OF SUMMARY OF TRAXSPOW@@TION PLANNED SUBMERSIBLE OPERATIONS U.

This funnel also acts as a receptacle for the surface rescue drop-lock. The float is equipped with a 2 Psi relief valve. High pressure air is piped up from the pilot's sphere-to a special adaptor that is attached to-the funnel and the float. When the float is pressurized from the sphere it expands and breaks away from the funnel and air connection. Fully inflated, the buoy has 281 pounds of positive buoyancy which overcomes the tension on the reel of the cable and streams it to the surface. Rescue Submersible rescue can be accomplished by dropping a specially designed drop-lock down the buoy line. The drop-lock is grooved on one side so the unit fits around the buoy line. The end is attached to 1500 ft. of rescue cable. The rescue winch is located on the submersible's support vessel. 0 ENCLOSURE (2) to COMDTINST 3130.7D 5 DEC 1975 Commander Commander 1st Coast Guard District 9th Coast Guard District Boston SAR Coordinator Cleveland SAR Coordinator Rescue Coordination Center Rescue Coordination Center 150 Causeway St. 1240 East 9th St. Boston,MA 02114 Cleveland, OR 44199 Phone No. (617) 223-3645 Phone No. (216) 522-3984 Commander Commander 2nd Coast Guard District l1th Coast Guard District St. Louis SAR Coordinator Long Beach SAR Coordinator Rescue Coordination Center Rescue Coordination Center Federal Building Heartwell Bldg. 1520 Market St. 19 Pne Ave. St. Louis, M0 63103 Long Beach, CA 908O2 Phone (314) 425-4614 Phone No. (213) 590-2225 Commander Commander 3rd Coast Guard District 12th Coast Guard District New York SAR Coordinator San Francisco SAR Coordinator Rescue Coordination Center Rescue Coordination Center Governors Island 630 Sansome St. New York, NY 10004 San Francisco, CA 94126 Phone No. (212) 264-4800 Phone No. (415) 556-5500 Commander Commander 5th Coast Guard District 13th Coast Guard District Portsmouth SAR Coordinator Seattle SAR Coordinator Rescue Coordination Center Rescue Coordination Center Federal Building 915 2nd Ave. 431 Crawford St. Seattle, WA 98174 Portsmouth, VA 23705 Phone No. (206) 442-5886 Phone No. (804) 393-9231 Commander Commander 14th Coast Guard District 7th Coast Guard District Honolulu SAR Coordinator Miami SAR Coordinator Rescue Coordination Center Rescue Coordination Center P.O.
