Fjord on Meta Incognita Peninsula Baffin

 

My prime fields of scientific curiosity are geomorphology, and the dynamics and evolution of ice sheets. Much of my research is centered on deciphering of subglacial landforms systems. The approach is two-pronged, one being subglacial conditions and the functional chain of subglacial landform preservation-reshaping-destruction, the other being credible reconstruction of paleo-ice sheet evolution.
Subglacial conditions, and in particular the spatial arrangement of frozen and thawed zones, including ice streams, is an important control on ice sheet height, flow pattern and ice discharge, and the variation of these parameters over time. The exposed beds of paleo-ice sheets, which integrate information of subglacial events over a long "time vindow", offer a rich but fragmented and difficult to interpret information source.
In order to improve our use of this record in ice sheet reconstruction I have spent much effort on developing a coherent and credible inversion model for the glacial geomorphological record. Current focal points in my research are ice sheet build-up and atmospheric circulation during conditions of intermediate glaciation, and also the crucial issue of ice sheet stability and the risk of partial ice sheet collapses.
