Abstract

The stability of the East Antarctic Ice Sheet and its contribution to past sea-level rise are not well defined; in this paper, airborne geophysical data and ice-sheet models are used to show that the Totten Glacier has undergone large-scale retreats and advances, and that it could contribute several metres of sea-level rise in a fully retreated scenario.
