Water in Helheim Glacier Makes Its Way to the Ocean

New NASA research found that large crevasses provide aquifer water upstream of Greenland's Helheim Glacier with a clear escape to the ocean. This discovery helps confirm that the water, which is held in a layer of crunchy, granular snow called firn, contributes to sea level rise.
