See summer warmth shifting sea ice in northern Greenland.
This animation, composed of MODIS images from the Terra and Aqua satellites from July 27 to August 1, 2018 (excluding July 28 due to cloud cover), shows the motion of the region’s sea ice, which is a bit more brisk than glacier movements. Some of the waters in the fjord systems of northern Greenland are covered with sea ice year-round. “Multiyear ice” in the area can survive several melt seasons and become fairly thick. That includes the region’s fast ice—a type of sea ice that clings to the shore—which can last for years at a time. But as the animation shows, there are also areas of seasonal ice cover that can melt and break up during the summer months.
