Does loss lead to instability?
02 August 2017
Thanks to the satellite era, we recently witnessed the birth of one of the biggest icebergs on record. While the break-up of Antarctica's Larsen C ice shelf hit the headlines around the world, this dramatic event also presents scientists with a unique opportunity to learn more about ice-sheet stability.
On 12 July, Europe's Copernicus Sentinel-1 mission returned radar images showing that a lump of ice more than twice the size of Luxembourg had broken off the Antarctic Peninsula.
Since then, this 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 has now also formed, the largest of which is over 13 km long.
