Arctic sea ice from CryoSat

Arctic sea ice time series display the change over time in sea ice thickness or volume over the whole Arctic, an ocean basin, or thickness at a point location.

Near real time data on Arctic sea ice is also available on the website within two days of CryoSat-2 passing over the ice.

Ice velocity

Our ice velocity data portal provides 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 Sentinel-1.


Antarctic Surface Elevation Change (SEC) from Satellite Altimetry

This provides elevation change in an Antarctic region or drainage basin. You can choose results from a specific satellite mission or period.
