Accelerating glacier mechanics
Videonummer 11919388
| Animation of the Greenland ice sheet melting during the summer, showing how meltwater causes the flow of glaciers to speed up. During the summer melt season, meltwater (cyan) accumulates in undulations on the surface of the ice sheet. Eventually, these melt lakes drain through crevasses or moulins (tunnels under the ice sheet surface), delivering water to the bottom of the ice sheet. Here, it lubricates the interface between the ice and the bedrock, causing the ice to flow faster toward the sea during summer. Once over the sea, the weight of the ice causes large chunks to break off, forming icebergs, a process known as calving. | |
