A rare dataset collected by instruments at the point where Antarctica’s largest ice shelf begins to float reveals ocean processes that drive melting at this critical part of the continent.
During a 2019 expedition to the Kamb Ice Stream, a river of ice which feeds the Ross Ice Shelf, we were able to deploy a string of hydrographic instruments into a thin wedge of ocean beneath the shelf where it begins to lift off at a latitude of nearly 83 degrees South.
