Abstract

GPR and high frequency seismometers were used to: a) Survey the glacier depth (0-180m), calculate the radar velocity through ice (0.174m ns-1), investigate the nature of subglacial thrust sheets (3m thick slices moving at 3m per year). b) Characterise the seismic signal and their sources. Seismic signals could be passed through a low pass filter of 250 MHz with little data loss. Five basal seismic events were identified, which occurred on warm dry days up to 3 hours after peak temperatures.
