SLIDING OF NON-TEMPERATE GLACIERS.

Abstract

It is shown that the temperature gradient normal to the bed is an important parameter in determining whether sliding can or cannot occur in a glacier whose bottom surface is at the melting point. Only if a large temperature gradient exists will sliding be prevented. Since the temperature gradient of a glacier whose bottom surface is at the melting point is expected to be small, it is concluded that sliding usually will occur in such a glacier even if obstacles in the bed may protrude into cold ice.
