Scheelebreen is a mid-sized glacier in central Svalbard which began a remarkably rapid surge in 2021. By February or March 2022, the surge front met the fjord turning this former land-terminating glacier into a tidewater-terminating glacier. Features on the sea ice at the terminus of the glacier show it being deformed as the surge enters the fjord. Ice speeds in March 2022 shows that the surge still has some way to go.

In this animation, Synthetic Aperture Radar (SAR) data from the Copernicus Mission Sentinel-1 satellite shows the development of the surge through the winter when it is too dark for optical instruments to collect data. The animation finishes with a true-colour Sentinel-2 image showing that spring has returned to Svalbard and monitoring can continue with optical instruments.
