Satellite imagery shows fragile Wilkins Ice Shelf destabilized
Date:4/28/2009

l laboratory that will allow us to understand how ice shelves respond to climate change and what the future will hold for the rest of Antarctica," Vaughan commented. "The quality and frequency of images acquired by ESA satellites mean that the break-up of Wilkins Ice Shelf can be analysed far more effectively than any previous event. For the first time, I think, we can really begin to see the processes that have brought about the demise of the ice shelf."

However, it is still unclear how the situation will evolve. Humbert noted that, "We are not sure if a new stable ice front will now form between Latady Island, Petrie Ice Rises and Dorsey Island. If the connection to Latady Island is lost, the projected loss of 3370 sq km of ice might be greater though we have no indication that this will happen in the near future."

The combination of high resolution TerraSAR-X images and the more frequently acquired Envisat images, increases the understanding of ice shelf break-up more than ever before.

ESA's Webcam from Space is available to the public and features the latest Envisat images, documenting the break-up of Antarctica's Wilkins Ice Shelf.
