OBSERVATIONS OF CONTINUOUS INSTABILITY FOR SCAR INLET ICE SHELF, ANTARCTIC PENINSULA

Observation of the evolving instability of ice shelves plays a very important role in global change research. Following the suddenly large-scale collapse of the Larsen B Ice Shelf in the Antarctic Peninsula in 2002, the evolving instability for its remnant, the Scar Inlet Ice Shelf, began to be incr...
