Seawater Intrusion in the Observed Grounding Zone of Petermann Glacier Causes Extensive Retreat

Abstract Understanding grounding line dynamics is critical for projecting glacier evolution and sea level rise. Observations from satellite radar interferometry reveal rapid grounding line migration forced by oceanic tides that are several kilometers larger than predicted by hydrostatic equilibrium,...
