New gravity-derived bathymetry for the Thwaites, Crosson, and Dotson ice shelves revealing two ice shelf populations
Ice shelves play a critical role in the long-term stability of ice sheets through their buttressing
effect. The underlying bathymetry and cavity thickness are key inputs for modelling future ice …
