This animation shows the total elevation changes across the Greenland Ice Sheet, as measured by ESA’s CryoSat and NASA’s ICESat-2 missions. The time series illustrates changes averaged over the ice sheet’s interior and margins, with blue representing CryoSat data and red representing ICESat-2 data.

The animation highlights how thinning is much greater at the margins than in the interior of the ice sheet, as highlighted by well-known examples of extreme thinning: Sermeq Kujalleq (also known as Jakobshavn Isbræ) and Zachariae Isstrøm.

Starting October 2018, the total elevation changes are from a combination of measurements form CryoSat and ICESat-2.
