B-15A iceberg monitoring - Antarctica (2004-2006)
Iceberg B-15A was a large fragment of a larger iceberg that calved from the Ross Ice Shelf in Antarctica in 2000. B-15 was the largest iceberg in any records and was 295 km long. B-15A drifted along the coast until it collided with the Drygalski ice tongue on 10 April 2005. This caused part of the ice tongue to break apart, and resulted in cartographers redrawing the map of Antarctica to address the 8 km2 section that had broken off. B-15A continued further along the coast until it made contact with the coast again on 27 October and broke apart into smaller pieces and drifted out into the open sea in 2006. This series of Envisat images monitor B-15A from November 2004 to February 2006, before and after the iceberg collided with the Drygalski ice tongue and the coast near Cape Adare in October 2005.

These two animations examine iceberg B15-A's impact with the Drygalski ice tongue from 04-20 April 2005. Acquired with Envisat's ASAR instrument, the radar images are Wide Swath Medium Resolution products and clearly depict the iceberg. The second animation is a magnified view of the impact.

These annotated images display pertinent information regarding the collision for reference. 
These images are the latest ASAR and MERIS acquisitions over B-15A and other fragments of the iceberg. They were received via link with the Artemis satellite in ESA/ESRIN.     19 Feb 2006 - WSM 13 Feb 2006 - WSM 29 Dec 2005 - GMM 06 Dec 2005 - GMM See the full gallery of ASAR images dating from 04 November 2004 to 19 February 2006.     09 Oct 2005 - 18877 05 Oct 2005 - 18820 02 Mar 2005 - 15714 17 Feb 2005 - 15527 See the full gallery of MERIS images dating from 17 January to 09 October 2005.
