Subglacial meltwater corridors and their relationship to the soft-bed subglacial hydrological continuum

The subglacial environment is a key part of glacier dynamics, and the ‘slipperiness’ of the bed has shown to be related to the rate of sea level rise. Investigations of the subglacial hydrological system associated with soft beds are rare. Studies from modern glaciers have revealed there is a continuum in subglacial fluvial behaviour associated with a deforming bed, from channelised to distributed. We use data from wireless in situ subglacial probes, GPR, glacier velocity data from remote sensing and GNSS and drone surveys to investigate this continuum. We then use this data to relate this to the geomorphology and sedimentology from both modern and Quaternary melt-water corridors, in order to reconstruct past subglacial processes.
