Diet Composition of Southern Beaufort Sea Polar Bears Sampled in Spring from 2004 to 2016 Estimated with Quantitative Fatty Acid Signature Analysis ...
These data are estimates of the proportional contributions of bearded seal, beluga whale, bowhead whale, and ringed seal to the diets of southern Beaufort Sea polar bears. Fat biopsy samples were collected from polar bears captured or biopsy darted along the north coast of Alaska or on offshore ice...
