In 2002 and 2004, the surveys were a continuation of those done in 1999 and 2000, taking advantage of the survey platform as it ran transects through SEBS. In 2008 and 2010, the cetacean survey was included as part of the Bering Sea Integrated Ecosystem Research Program, a NPRB funded project to test and improve our understanding of effects of climate change and management actions on the Bering Sea ecosystem. Methods in all years were the same with three observers rotating through two 25x (Big Eye) binocular positions and one recorder on the flying bridge. Survey effort was conducted along the pollock survey ...
