Rapid submarine ice melting in the grounding zones of ice shelves in West Antarctica
Nature Communications, 2016 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 ...
