“The calving occurred sometime between Monday, July 10 and Wednesday, July 12, when a 5,800-square kilometre (2,200-square mile) section of Larsen C (ice shelf) finally broke away,” the Swansea University said in a statement.

Reported to be “ hanging by a thread ” last month, the trillion-tonne iceberg was found to have split off from the Larsen C section of the Larsen ice shelf on Wednesday morning after scientists examined the latest satellite data from the area.The Larsen C ice shelf is now 10% smaller than before the iceberg broke off – or “calved” – an event that researchers say has changed the shape of the Antarctic peninsula and left the Larsen C ice shelf at its lowest extent ever recorded.
