Iceberg A-76



In mid-May 2021, A-76 was, before it broke into three, the world's largest floating iceberg, calved from the Filchner–Ronne Ice Shelf in Antarctica.

The new iceberg, effectively a piece of floating ice shelf, detached from the western side of the ice shelf. It floated through the Weddell Sea and by 2023 had reached the South Atlantic near South Georgia, carried by currents and winds. The iceberg is about 170 km long and 25 km wide, and is described as being shaped like a "giant ironing board", and roughly the size of Cornwall. The size at calving was an estimated 4320 km2. The new iceberg was first spotted by Keith Makinson, a polar oceanographer with the British Antarctic Survey in May 2021.

By day 148, the iceberg consisted of three fragments, A-76a, A-76b, and A-76c.
