Freeze-on limits bed strength beneath sliding glaciers

Across all glaciers, ice caps, and ice sheets, the gravitational driving stress, and therefore the average basal shear stress falls in a narrow range that tops out around 1 bar. Here, the authors show that the mechanical resistance posed by heterogeneous infiltration of ice into sediments governs th...
