This new NASA/UC Irvine map of Antarctic ice velocity. It is needed in Antarctica for now it’s is 10 times more accurate. More than any previous map. It also shows flows over 80% of the continent. For starters it goes further because older maps showed about 20%. Colored lines indicate direction of flow; background colors show speed.
Far more accurate than any previous map, this new representation of glacier flows in Antarctica. It therefore opens the door to an improved understanding of the vast continent. As well as and more importantly, the future pace of sea level rise. To create the new map, researchers at the University of California, Irvine, and NASA’s Jet Propulsion Laboratory in Pasadena, California, combined input from six different satellite missions dating from 1994 to the present.
