IAB Research Project Description

Ice Seal Stable Isotopes

Ribbon seals use the marginal sea ice zone in the Bering and Okhotsk Seas for reproduction, molting and as a resting platform. In the summer and fall, they forage in the Bering and Chuckchi seas. Credit: NOAA.

Any and all uses of these images must include photographer credit.

The Wildlife Toxicology Laboratory (WTL) will work collaboratively with the Alaska Department of Fish and Game (ADF&G) to study the foraging ecology of ribbon and spotted seals in the Bering Sea to help understand the influence of feeding ecology on mercury contaminant exposure in these species. Staff from the WTL will prepare Steller sea lion whisker samples for analysis of stable carbon and nitrogen isotope content and deliver about 960 samples to the UAF Stable Isotope Laboratory for analysis.
