The Aerial Surveys of Arctic Marine Mammals (ASAMM) project was initiated in 2011 and is a continuation of surveys conducted since 1982. Aerial surveys remain the only practical means of assessing marine mammal distribution, population density, and habitat use in large study areas. The goal of this study is to investigate the distribution and relative abundance of marine mammals in the western Beaufort and northeastern Chukchi seas during the open water (ice-free) months of June-October 2012, when various species are undertaking seasonal migrations through the study area to and from seasonally occupied habitats both within and adjacent to the study area.
