🐋 Sea ice disappearing in East Greenland allows whales to move into previously inaccessible areas, increasing access to capelin and krill resources.
Now, as climate change warms the sea and melts the ice, a new world opens up to them.

Giant whales move into Greenland waters as ice disappears
Melting sea ice from climate change has opened up the region for giant whales to undertake "feeding frenzies".

Our recent study in Ecological Modelling shows that southern right whale mother-calf pairs leave calving grounds once calves reach ~8 m in length, not after a fixed time. Larger, fatter mothers help calves reach departure size faster! 🐋⚡
