Pacific Coast Feeding Group (PCFG) gray whales

See also North Puget Sound Gray Whales

This is a long terms study Cascadia began in the 1980s and since 1998 has coordinated a collaborative photo-ID effort along the US West Coast tracking identified gray whales. Over 2,000 different individuals are tracked by their natural markings as a part of this research and used to estimate abundance, trends, and movements of primarily the animals that summer and feed in the Pacific Northwest but also some of those that migrate through these waters on route to other feeding areas. 

Original publication on western gray whale photo-ID matches: A publication that just came out in Endangered Species Research coauthored by Cascadia researchers Amber Klimek and John Calambokidis reports on movements of gray whales between what was thought to be a feeding area for a separate population of western Pacific gray whales off Russia and feeding and breeding areas in the eastern North Pacific. This surprising result along with satellite tag data from a coalition of US and Russian researchers is changing our view of the status of gray whales in the western North Pacific.
