Uppermost crustal structure regulates the flow of the Greenland Ice Sheet

Anomalously slow seismic velocities in the upper Greenlandic crust reveal soft sedimentary substrates beneath major outlet glaciers. This, together with elevated geothermal heat flux observed at the onset of fast ice flow, has major implications for ice-sheet dynamics.
