Rapid submarine ice melting in the grounding zones of ice shelves in West Antarctica

Ice-shelf bottom melting is thought to cause mass loss in West Antarctica. Here, the authors analyse radar observations of the Dotson and Crosson ice shelves to directly quantify grounding zone unbalanced melting of up to 70 m per year, and illustrate its relation with bed topography and grounding l...

Description
Summary:Ice-shelf bottom melting is thought to cause mass loss in West Antarctica. Here, the authors analyse radar observations of the Dotson and Crosson ice shelves to directly quantify grounding zone unbalanced melting of up to 70 m per year, and illustrate its relation with bed topography and grounding line retreat.
