Abstract

Most of the velocity of ice stream B near the upstream B CAMP (UpB), West Antarctica, appears to arise from deformation of a seismically detected, subglacial till layer that averages 6 m thick. The resulting till flux beneath UpB is equivalent to an average erosion rate of about 0.4 mm yr -1 in the catchment area and suggests that till deltas tens of kilometers long have been deposited at the grounding line during the Holocene. -from Authors
