Carbon and Nitrogen Isotope Concentrations in Polar Bear Hair and Prey from the Alaska Beaufort and Chukchi Seas, 1978-2019
This dataset includes carbon and nitrogen isotope concentrations measured in polar bear hair and marine mammal prey samples collected 1978-2017 in the Beaufort and Chukchi Seas. Marine mammal prey samples were collected opportunistically either from polar bear seal kill sites or from marine mammals...

Whole hairs were analyzed for carbon and nitrogen isotopes. Prey samples were analyzed separately as blubber lipids, blubber protein (with lipids extracted), bulk muscle, and lipid-extracted muscle.
