Jakobshavn Glacier

Caption

Icebergs choke the fjord where Jakobshavn glacier flows into the sea off western Greenland. A new analysis shows that the mechanisms that drive the seasonal ebb and flow of some Greenland glaciers are different from those driving longer-term trends like overall retreat of glaciers, and faster flows. Lead author of the Journal of Geophysical Research paper, CU-Boulder's Twila Moon, said she hopes it will help scientists better anticipate how a warming Greenland will contribute to sea level rise.
