Larsen B Ice Shelf, Antarctic Peninsula

January 18, 2006
This is one of the very first images acquired by Envisat, ESA's Earth observation satellite in March 2002. The collapse of the Larsen B ice shelf observed on 18 March 2002.The Antarctic Peninsula has experienced exceptional atmospheric warming over the last decades, triggering the retreat and break-up of the ice shelves. The launch of Envisat occurred just in time to capture the disintegration of the Larsen B ice shelf. This image shows that the collapsed ice shelf has fractured into thousands of small icebergs, drifting eastwards into the Weddell Sea. This kind of break up is quite different from the periodic calving processes taking place 1000 km further south which have led to the presence of the large drifting icebergs seen in the image.
