Map of subglacial lakes shows how the Arctic environment is changing

Researchers have created the first map of a network of subglacial lakes in the Canadian Arctic showing 33 bodies of water under glaciers. Using a decade of ArcticDEM satellite data of the Earth’s surface height, a team of researchers including the University of Waterloo developed a method that allowed them to track the draining and filling of active subglacial lakes in unprecedented detail.
