This Tuesday, Feb. 1, 2022 satellite image from the European Space Agency, annotated by marine geophysicist Robert Larter, shows the positions of research vessels RVIB Nathaniel B. Palmer and the RV Araon on Feb. 2., on the ice shelf areas extending from Thwaites Glacier in Antarctica.  & quot; EIS & quot;  indicates the Eastern Ice Shelf where a lot of work was conducted in 2020, and which recently published studies have suggested is likely to break up sometime within the next couple of decades.
