A81 covers1,340 sq km, about size of greater London

A massive Antarctic iceberg, known as A81, covers around 1,340 square kilometres — nearly the size of Greater London. The iceberg broke away from Antarctica’s Brunt Ice Shelf in January 2023 after a major crack, known as Chasm 1, extended through the ice. The giant ice formation highlights the dramatic changes unfolding across Antarctica’s frozen landscape.
