Envisat Global Monitoring Mode mosaic of Antarctica using data acquired during April and May 2004. Working in GMM, the ASAR instrument 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.
Here, ASAR GMM has mapped the Antarctica Continent to detect and monitor iceberg drift. A multitude of scans was performed over the Amery Sea in East Antarctica from April 1st to May 30, 2004. By combining all data, the displacement of icebergs, among which are the B-15D - seen to the right hand side of the image, appearing as multiple icebergs - can be highlighted.
