This animation shows the giant slab of ice breaking off from the Ronne Ice Shelf, lying in the Weddell Sea, on May 13. “Over coming weeks or months, the iceberg may move away or it could run aground and remain close to Brunt Ice Shelf,” Francis said in the statement. A vast iceberg equivalent to the size of Greater London has broken off the Antarctic ice shelf. The world’s largest iceberg, dubbed A-76, has calved from Antarctica. Scientists are now watching the iceberg to see what it will do next. This is the widest glacier on earth, at 70 miles across, draining an area. “Change in the ice at Halley is a natural process and there is no connection to the calving events seen on Larsen C Ice Shelf, and no evidence that climate change has played a significant role,” according to the BAS. Toward the coast of West Antarctica is a large area of ice called Thwaites Glacier. The loss of a glacier the size of Florida in Antarctica could wreak havoc on the world as scientists expect it would raise global sea levels up to 10 feet. The ice shelf flows toward the sea at a rate of about 2 kilometers per year and icebergs break off at irregular intervals. There have been six Halley Research Stations in place on the Brunt Ice Shelf since 1956 to make atmospheric and space weather observations. Is an iceberg weighing hundreds of billions of tons on a penguin collision course?Īn even bigger iceberg broke away from the Larsen C Ice Shelf in 2017 and floated into the open ocean late last year. The worlds biggest iceberg, A-68, just got a little smaller. Iceberg A68a, photographed by European Space Agency satellite Sentinel-3 on December 9, approaches South Georgia in the South Atlantic.
