An iceberg, a bit smaller than Prince Edward Island, has calved from the Filchner–Ronne Ice Shelf in Antarctica. The Filchner-Ronne Ice Shelf is in the Weddell Sea.

The iceberg has detached from the western side of the Ronne Ice Shelf. The iceberg is about 170 km long and 25 km wide. The size at calving was an estimated 4320 square km.

Last Friday the U.S. National Ice Center said on Twitter that, "Iceberg A-76 calves from the western side of the Ronne Ice Shelf in the Weddell Sea and is currently the largest iceberg in the world."

The shape of the iceberg is being described as an ironing board.

The largest iceberg in history was B-15 that calved off Antarctica 21 years ago. B-15 was about 11,000 square kilometres.
