Sea Ice in Baffin Bay (IMAGE) University of Washington Caption The study compared the movements of adult female polar bears during two time periods. In the 1990s (left), sea ice in mid-July still spanned Baffin Bay, providing polar bears with a large area to hunt and travel. In more recent summers (right), Baffin Bay was mostly open water in mid-July, and polar bears were stuck closer to shore.
