Greenland Thaw: Measuring Change

Subscribe to Greenland Thaw: Measuring Change feed
Greenland’s ice sheets are shrinking faster than ever, responsible for about a quarter of sea-level rise globally. Alison Glacier on Greenland’s northwestern coast is one place where ice flow to the sea has speeded up. From a tiny hunting and fishing village in the Upernavik Islands, scientists from Columbia University’s Lamont-Doherty Earth Observatory will take ocean measurements to understand why Alison is surging to the sea faster than nearby glaciers. They will also work with villagers to continue data collection when they’re gone.
