This unusual view is what scientists look at to analyse changes and movements of sea ice. The animation consists of Envisat ASAR mosaics of the Arctic Ocean acquired in mid-August 2011. The Arctic is one of the most inaccessible regions on Earth, so obtaining measurements of sea ice was difficult before the advent of satellites.
