Abstract

On 11 April 2026, a polar bear (Ursus maritimus) was observed approximately 150 m from the partially consumed carcass of a small cetacean that lay on the sea ice. The observation was made from a trawler operating in heavy sea ice in the Labrador Sea, about 110 km off the coast of Newfoundland and Labrador, Canada.
