A 20-Meter-High, Nearly 14-Kilometre-Long Iceberg Ran Aground Between an Emperor Penguin Colony and Its Antarctic Feeding Area: the Number of Surviving Young Fell by 69% in Just One Season
An iceberg of almost 14 kilometers was stuck in the north of Coulman Island, in the Ross Sea, just as the emperor penguins began to raise their chicks. In two aerial surveys in November and December 2025, researchers counted 6,658 live offspring, 69% less than in 2024 and the average recorded since 2017.
