Biologically Important Areas II for cetaceans within U.S. and adjacent waters – Gulf of Alaska Region
We delineated and scored Biologically Important Areas (BIAs) for cetacean species in the Gulf of Alaska region. BIAs represent areas and times in which cetaceans are known to concentrate for activities related to reproduction, feeding, and migration, and also the known ranges of small and resident p...

We delineated and scored Biologically Important Areas (BIAs) for cetacean species in the Gulf of Alaska region.
