National Science Foundation Funds Brunt's Study Of Antarctic Ice Flow

Kelly Brunt received funding from the National Science Foundation’s Division of Polar Programs to support a two-year study of the flow of the Ross Ice Shelf in Antarctica. This ice shelf, together with the Filchner-Ronne Ice Shelf, buttresses the seaward flow of the West Antarctic Ice Sheet, the portion of Antarctica’s grounded ice that is most at risk of catastrophic disintegration and is currently the largest Antarctic contribution to sea level rise.

Brunt’s project will develop a model that explores how ocean tides modulate the movement of land ice toward the sea and will use existing GPS measurements to evaluate the model's results.
