Watch the big polar glaciers moving for first time

Centre for Polar Observation & Modelling has launched the ice sheet outlet glacier velocity service using satellite data.

Through this data portal, they distribute frequent maps of ice velocity for key outlet glaciers of the Antarctic and Greenland ice sheets in near real time. 

The velocity maps are produced by tracking moving features in synthetic aperture radar data acquired by the European Space Agency's Sentinel-1 satellite.

The BBC's Science Correspondent Jonathan Atmos featured the launch: http://www.bbc.co.uk/news/science-environment-36051112.
