This EUFAR project looked at ice-sheet evolution over the Quaternary and the sensitivity of the ice sheet to possible changes in atmosphere and ocean in East Antarctica.
The ultimate goals of this project were(i) to decipher regional ice-sheet evolution over the Quaternary and (ii) to examine the sensitivity of the ice sheet in this area to possible changes in atmosphere and ocean. The observational goals of this project were surface and bed topography, englacial structures (i.e. internal reflecting layers, if existing) as well as radar power returned from within and beneath the ice (a proxy of basal water). Since the proposed study area has extended crevassed zones, ground access to these areas is impossible for safety reasons. Using airborne data together with supplemental data collected by other projects, will enable constraints to ice-flow models to clarify geological controls on ice flow, dynamic coupling of adjacent fast-flow features, and ultimately examine their effects on magnitudes and timing of ice flux to the ocean for a range of external forcing.
