Research opportunities exist within the JPL/UC Irvine Ice Sheet Modeling Initiative to develop numerical models capable of more reliable projections of glacier and ice sheet evolution in a warming climate. The numerical models are high-resolution, higher-order, three-dimensional finite element models, coupled with airborne (thickness, surface elevation) and satellite observations (interferometric radar measurements of ice velocity, laser elevation), forced by output products from regional atmospheric (surface mass balance) and oceanic (basal melt) circulation models. Our research focuses on the utilization of massively parallelized techniques for ice sheet modeling, the study of ice motion and grounding line dynamics using spaceborne radar interferometry, and the numerical simulation of ice-ocean interactions in tidewater glaciers and beneath ice shelves. Research opportunities exist in both the development of these techniques and in their utilization to improve our understanding of the evolution of glaciers and large ice masses to improve projections of ice sheet evolution in a warming climate.
