Possible signs of recovery of the nearly extirpated Spitsbergen bowhead whales: calves observed in east Greenland

Polar Research, 2023
The Spitsbergen population of bowhead whales (Balaena mysticetus) was harvested to near extinction during the whaling era. Here, we show possible signs of recovery of the population by reporting observations of two calves in the Scoresby Sund polynya in ...
