Now, researchers have shown that baleen whales are taking advantage of a newly opened-up fish bonanza in the Greenland Sea, east of Greenland and reaching to the Arctic Circle and beyond.

Common ground

"Here we show that rising ocean temperatures and declining sea ice cover have facilitated the widespread occurrence of baleen whales along the East Greenland coast, as far north as 70°N," said Professor Mads Peter Heide-Jørgensen of the Greenland Institute of…
