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.

Launched last week, Europe's Sentinel-5P satellite - the first Copernicus mission dedicated to monitoring the air we breathe - is in excellent health.
The satellite will use its state-of-the-art Tropomi instrument to monitor our atmosphere, mapping a multitude of gases that affect the air we breathe, our climate and human health.
