Acoustic impedance and basal shear stress beneath four Antarctic ice streams
The acoustic impedance of the subglacial material beneath 7.2 km profiles on four ice streams in Antarctica has been measured using a seismic technique. The ice streams span a wide range, of dynamic conditions with flow rates of 35-464 in a(-1). The acoustic impedance indicates that poorly lithified...
