Massive Iceberg Breaks Off from Antarctica's Brunt Ice Shelf

The 380 sq km iceberg, named A-83, marks the third major calving event in four years and reduces the ice shelf to its smallest extent since monitoring began.

Overview

  • The iceberg, roughly the size of the Isle of Wight, broke off on May 20 from the Brunt Ice Shelf.
  • This calving follows a prolonged weakening of the ice and the extension of the Halloween Crack.
  • Scientists state that the calving is part of natural ice shelf behavior and not directly linked to climate change.
  • The event does not pose a threat to the currently unmanned Halley VI Research Station.
  • The calving could impact local ocean circulation and the stability of nearby penguin colonies.
