He added that the Ronne Ice Shelf has "behaved in a stable, quasi-periodic fashion" over the past century. Scambos said that the ice shelf was already floating in the sea before breaking off, so the event does not raise ocean levels, whereas glaciers and ice sheets, found on land, do raise sea levels when they break off into the ocean. National Ice Center (USNIC) the next day using images from the Sentinel-1A satellite. The iceberg, known as A-76, was first spotted by a British Antarctic Survey researcher May 13. Ted Scambos, a research glaciologist at the University of Colorado at Boulder, told Reuters that this calving does not appear to be linked to climate change. A massive chunk of ice broke off of Antarctica this month, and it is now the largest iceberg in the world. Periodic calving of ice shelves is part of a natural cycle.

An animation shows iceberg A-76 breaking off from Antarctica. That iceberg measured about 93 miles long and 30 miles wide. It broke away from PIG last week, while the other, a trillion-ton behemoth dubbed A-68, broke away from the Larsen C Ice Shelf. Iceberg A68a, which was at one point the world's largest, was set on a collision course with a remote South Atlantic island last November, threatening the home of thousands of penguins and other wildlife, but broke into smaller chunks before it reached the island. B-49 is one of two large icebergs now floating away from Antarctica.

The mammoth slab of ice is the biggest iceberg on the. Following the calving of the A-81 iceberg at the end of January 2023, the Brunt Ice Shelf in Antarctica is moving faster than before.

(Copernicus Sentinel satellite imagery obtained by Pierre Markuse) There’s a new iceberg off the. The event pushes iceberg A-23A, which is 1,305 square miles and also floating in the Weddell Sea, into second place for the world's largest icebergs. Glaciologists are also keeping a close eye on another giant iceberg, A76A, which broke off from Antarcticas Ronne Ice Shelf in May 2021. An iceberg that broke off the Brunt Ice Shelf in Antarctica.
