Female and young walruses depend on disappearing Arctic sea ice for food sources

A new study shows that disappearing sea ice is a significant element of the food web supporting female walruses and their dependent young in the Arctic's Chukchi Sea. Researchers were able to trace biomarkers that are unique to algae growing within sea ice to connect marine mammals with a food source that is rapidly diminishing in the face of climate change.
