IDyRA aims at improving our knowledge of the interaction between the ice sheet and the ice shelf (Antarctic grounding zones). It specifically aims at
understanding the processes of subglacial melting and basal sliding by combining englacial information obtained from radio-echo sounding surveys
withstate-of-the-art higher-order ice sheet models. This way, numerical ice-sheet models can be validated by reconstructing the internal layer architecture.Grounding
lines are key areas in ice sheets and at present subject to much attention. IDyRA will improve the understanding of grounding line migration, ocean
interaction, and the role of buttressing in east Dronning Maud Land, Antarctica, where the marine ice sheet is buttressed by numerous ice rises. Results of the
project will contribute to a quantitative interpretation ofmelting under the ice shelf, its effect on ice sheet behavior and the effectof a thermohaline
circulation under the ice shelf.
