This image of the Petermann Glacier in northwest Greenland was captured by the Copernicus Sentinel-2 mission on 16 September 2022.
Petermann is one of the largest glaciers connecting the Greenland ice sheet with the Arctic Ocean. Upon reaching the sea, a number of these large outlet glaciers extend into the water with a floating ‘ice tongue’. Icebergs occasionally break or ‘calve’ off these tongues. Petermann’s ice flow has accelerated in recent years. Land-based glaciers in Greenland are a major contributor to global sea-level rise and as global temperatures warm, more ice is expected to melt into the oceans.
