This animation, made up of eight Envisat radar images, shows the 97-km long B-9B iceberg (right) ramming into the Mertz Glacier Tongue in Eastern Antarctica in early February 2010. The 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 2500 sq km (the size of Luxembourg).
Envisat’s Advanced Synthetic Aperture Radar (ASAR) acquired these images from 10 February to 4 March in Wide Swath Mode, providing spatial resolution of 150 m. ASAR can pierce through clouds and local darkness and is capable of differentiating between different types of ice.
