A team of scientists, led by British Antarctic Survey (BAS), heads to Antarctica this week (14 February) to investigate a mysterious marine ecosystem that’s been hidden beneath an Antarctic ice shelf for up to 120,000 years. The iceberg known as A-68, which is four times of London, calved off from the Larsen Ice Shelf in July 2017.2 comments
An iceberg the size of Delaware has broken free from an Antarctic ice shelf, leaving the rest of the shelf vulnerable to collapse and serving as a harbinger of future sea-level rise that could pose a serious threat to coastal communities such as the Falkland Islands.
Antarctica’s Larsen C ice shelf deep crack continues to cut across the ice, leaving a huge chunk clinging on. When it eventually gives way, one of the largest icebergs on record will be set adrift, and whole or in pieces, ocean currents could drag it north, even as far as the Falkland Islands. And if so it could pose a hazard for ships in Drake Passage.
