Baleen Whale Sightings Surge Off Eastern Greenland as Sea Ice Retreats

A New Scientist reporter documented multiple species lunging through dense prey patches near Scoresby Sound in 2024, an area that was largely inaccessible two decades ago. The event aligns with long-term monitoring by Greenland's Institute of Natural Resources showing humpback and fin whale counts rising from near-zero post-whaling lows to hundreds of individuals during summer months. Acoustic and visual survey data indicate the increase tracks both legal protection and the northward expansion of krill and capelin as ice cover declines. Climate-driven habitat opening explains much of the spatial shift, yet the same warming reduces overall Arctic productivity and may concentrate whales into fewer viable zones. Continued ship traffic and potential new fisheries create collision and entanglement risks not fully quantified in current models. Systematic aerial and satellite tagging programs over the next decade would separate recovery effects from redistribution and test whether the current abundance holds as ice-free periods lengthen.
