Toward a universal glacier slip law
Glaciers and ice sheets shape Earth's surface and are important components of the climate system. Among the notable effects of glacier flow are erosion and sedimentation of Earth's surface and variations in sea level as glaciers lose or gain mass. These effects depend on the slip of glacie...

Glaciers and ice sheets shape Earth's surface and are important components of the climate system.
