Abstract

Despite several decades of satellite and airborne geophysical surveys over the Greenland Ice Sheet (GrIS) there is still much that we do not know about the properties of the bedrock that lie beneath the ice, and to what extent basal characteristics influence ice dynamics. Whilst surveys were initially conducted to better constrain future sea-level rise contribution from glaciological modelling, radio-echo sounding (RES) has the potential to reveal basal characteristics relevant to both contemporary and palaeo-ice dynamics, and information regarding geology, landscape alteration and genesis.

This talk will detail several examples of this ‘extra’ information to be gleaned from RES conducted as part of my PhD research, as well as some future avenues for investigation.
