NEW YORK - Deploying an underwater robot beneath a rapidly melting ice shelf in Antarctica, scientists have uncovered new clues about how it is melting. The findings will help assess the threat it and other ice shelves pose for long-term sea-level rise.
The research “is telling us a lot more about the processes that drive retreat on Thwaites”, said one of the scientists, Mr Peter E.D. Davis, an oceanographer with the British Antarctic Survey. The findings, published on Wednesday in the journal Nature, will be used to refine models that forecast Thwaites’ long-term future.
The new findings were in two papers in Nature: Davis was the lead author of one, and Dr Britney E. Schmidt, a geophysicist at Cornell University, was the lead author of the other. Dr Alastair Graham, an oceanographer at the University of South Florida who has studied the historical retreat of the Thwaites ice but was not involved in these two studies, said that the work by Mr Davis’ team showed that “there is plenty of heat making its way all the way up to Thwaites grounding zone”.Members of the British Antarctic Survey team boring a hole in the Thwaites ice shelf to deploy instruments under the ice.
