Description

As a result of a deep cracking cutting across the Larsen C ice shelf, a huge iceberg was spawned on 12 July 2017. Europe’s Copernicus Sentinel-1 mission was used to monitor the rift’s progress, a network of fractures in the ice and the calving event. Since then, the large tabular iceberg – known as A68 – has drifted about 5 km from the ice shelf. Images from Sentinel-1 also show that a cluster of more than 11 smaller icebergs have now also formed, the largest of which is over 13 km long. These ‘bergy bits’ have broken off both the giant iceberg and the remaining ice shelf.
