The European Space Agency has a web page animation of imagery from Envisat’s Advanced Synthetic Aperture Radar (ASAR) instrument, that shows the breaking away of a giant iceberg from the Pine Island Glacier in West Antarctica. The newly formed iceberg covers an area of 34 km in length by 20 km in width.
The animation highlights the movement in the area between September 2006 and October 2007. The Pine Island Glacier is visible stretching from the right of the image to the centre. The tongue of Pine Island is shown moving inland between September 2006 and March 2007. Between April and May 2007, the detached iceberg in front of Pine Island moves significantly. Also in May 2007, a crack in Pine Island becomes visible. By October, the new iceberg has completely broken away.
