Collision in Antarctica seen from space

Mertz glacier tongue, Eastern Antarctica, February–March 2010

An animation, made up of eight Envisat radar images, shows the 97 km long B-9B iceberg ramming into the Mertz glacier tongue in Eastern Antarctica in early February.

Mertz glacier calving by EnvisatThe collision caused a chunk of the glacier’s tongue to snap off, giving birth to another iceberg nearly as large as B-9B. The new iceberg, named C-28, is roughly 78 km long and 39 km wide, with a surface area of 2,500 sq km (the size of Luxembourg). It was the Advanced Synthetic Aperture Radar (ASAR) on board the Airbus Defence and Space-built Envisat which acquired these images from 10 February to 4 March in wide swath mode, providing spatial resolution of 150 m. The Airbus Defence and Space ASAR instrument can pierce through clouds and local darkness and is capable of differentiating between different types of ice.
