This 16 May 2005 Envisat ASAR Wide Swath Mode (WSM) image shows the bottle-shaped B-15A iceberg adjacent to the landfast Aviator Glacier ice tongue, towards the top of the image. The Drygalski ice tongue, towards the base of the image, was struck a glancing blow by the drifting B-15A a month earlier. Pieces of Drygalski broken off by the blow can be seen drifting through the sea on either side of B-15A.

This view of the entire continent of Antarctica is a mosaic of Envisat ASAR Global Monitoring Mode images acquired between 1 and 10 January 2005. The Ross Ice Shelf and McMurdo Sound are at the bottom side of the image. Working in GMM, the ASAR nstrument can provide regular information on areas such as Antarctica where, due to constant cloud cover, the use of optical data is unable to support scientific investigations.
