RECENT VARIATIONS OF LARSEN ICE SHELF, ANTARCTIC PENINSULA, OBSERVED BY ENVISAT
Areal changes of Larsen Ice Shelf, Antarctic Peninsula, and the response of the outlet glaciers after the ice shelf disintegration events in 1995 and 2002 are investigated using ERS SAR and Envisat ASAR data up to July 2004. After a decrease of 8050 km 2 between January 1995 and March 2002, the ice...
