Heavy sea ice conditions have thwarted a science mission from reaching the Larsen C Ice Shelf in Antarctica from which a large iceberg broke off in July 2017. A team of scientists, led by British Antarctic Survey (BAS), are travelling on board the RRS James Clark Ross. Sea ice, up to 4-5 meters thick, has made progress for the ship very slow and on 28 February) the ship’s captain made the difficult decision not to continue.
A team of international scientists led by the British Antarctic Survey set off on Wednesday to explore a mysterious marine ecosystem that has lain hidden under an ice shelf for up to 120,000 years.
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.
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.
