Decades-long growing rift in Brunt Ice Shelf finally breaks, creating new iceberg, Antarctica

On January 22, 2023, a massive rift on the Brunt Ice Shelf in Antarctica finally gave way, resulting in the formation of a new iceberg measuring 1 550 km2 (~600 mi2). The U.S. National Ice Center has named it Iceberg A-81. The rift, spanning most of the Brunt Ice Shelf in Antarctica, appeared ready to spawn an iceberg in 2019, posing an uncertain future for scientific infrastructure and a human presence on the shelf that was first established in 1955 by the British Antarctic Survey (BAS).
