Inhalt:
Grounding zones mark the boundary between grounded and floating parts of a marine terminating ice sheet. This is the most appropriate boundary for estimating the balance between outgoing ice fluxes and snow accumulation and is the point past which the ocean can influence and interact with the ice sheet. Here, we present evidence of how grounding line dynamics affect glacier flow and how it affects uncertainties in seal level projections. The proposed synergistic approach enables the characterization of grounding line migrations, impact on thinning and ice bottom melt and sheds new lights on the physical processes controlling grounding line migration.
