The ebb and flow of Greenland's glaciers

Mon, 01/06/2015 - 4:25pm
In northwestern Greenland, glaciers flow from the main ice sheet to the ocean in see-sawing seasonal patterns. The ice generally flows faster in the summer than in winter, and the ends of glaciers, jutting out into the ocean, also advance and retreat with the seasons. Now, a new analysis shows some important connections between these seasonal patterns, sea ice cover and longer-term trends.
