Scientists Map the Ice Sheets of Antarctica and Greenland

Ice sheets are huge sheets of ice that are larger than 50,000 square kilometers. Earth has just two ice sheets: the Antarctic Ice Sheet and the Greenland ice sheet. German scientists have made contour maps of the height or elevation of these two ice sheets. They used radar beams and a satellite, the CyroStat-2, to help them develop maps of elevation changes across these very large sheets of ice. These maps, or digital elevation models, not only show the current heights of the ice sheets, but also show the changes in elevation from 2011-2014.
