Rapid Bottom Melting Widespread near Antarctic Ice Sheet Grounding Lines

As continental ice from Antarctica reaches the grounding line and begins to float, its underside melts into the ocean. Results obtained with satellite radar interferometry reveal that bottom melt rates experienced by large outlet glaciers near their grounding lines are far higher than generally assu...
