Sentinels warn of dangerous ice crack
16 February 2017
Following the appearance of a large crack in the ice shelf close to the Halley VI research station in Antarctica, information from the Copernicus Sentinel-1 and Sentinel-2 satellites helped to decide to close the base temporarily.
Nourished by an inflow of ice from grounded glaciers and snow accumulating on its surface, Brunt Ice Shelf is a floating ice sheet in the Weddell Sea Sector of Antarctica. The floating ice moves steadily towards the ocean, where it occasionally calves off as icebergs.
Cracks often appear on shelves as the ice deforms. However, rapidly expanding cracks indicate impending calving.

With the Sentinel-2B satellite close to beginning its working life in orbit, this latest Copernicus satellite has linked up to Alphasat by laser, across almost 36 000 km of space, to deliver images of Earth just moments after they were captured.
The test, which was done as part of Sentinel-2B's commissioning, included capturing a strip of images from Europe to North Africa.
