This Project Grant award, valued at $703,638, was provided by the National Science Foundation's Polar Programs (CFDA 47.078) to Columbia University. The funding supports research aimed at advancing the understanding of the dynamic interaction between mantle flow, crustal deformation, and topography beneath Antarctica since the inception of the Antarctic ice sheet 34 million years ago. Key objectives include addressing the evolution and uplift of the Marie Byrd Land hotspot, investigating the interplay of mantle processes and tectonic forces during rift evolution in the West Antarctic Rift System, and evaluating how buoyancy-driven mantle flow interacts with glacial isostatic adjustment. The research will use advanced computer simulations and seismic imaging data to recreate the history of these deep earth processes and their impact on the Antarctic landscape and climate system. The results are expected to improve predictions of future sea level rise by providing better estimates of how the ground beneath the Antarctic ice sheet changes over time.
