Full title

High basal shear stress vs. high basal melt: Accelerations on the Getz Ice Shelf, West Antarctica.

Abstract

Ice shelves—floating extensions of ice sheets—help to regulate the flow of grounded ice off of continents. Therefore, we must understand ice shelves in order to understand and project rates of global sea level rise. The Getz Ice Shelf, which drains part of the West Antarctic Ice Sheet, lies in the most rapidly changing region of Antarctica. This study examines the ice velocities across the Getz as an initial investigation into the dynamic responses of the shelf to a complex array of oceanic and climatic forcings.
