Split in the Larsen C ice shelf will release an iceberg a quarter of the size of Wales, changing the landscape of the Antarctic peninsula A giant section of an Antarctic ice shelf is hanging by a thread and could break off at any moment, researchers have revealed. The split in the Larsen C ice shelf of the Antarctic peninsula will release a huge iceberg 5,000 sq km in size – an area about a quarter of the size of Wales. “The rift is nearly 200km long now, and it has turned towards the ice front, suggesting that it has only got that last piece to go – and that last section is only 13km,” said Professor Adrian Luckman, a scientist at Swansea University and leader of the UK’s Midas project – an endeavour that has been monitoring the situation at the Larsen C ice shelf.
