Antarctica - January 25th, 2009

This radar (ASAR) images shows several different features of the ice in Antarctica.

The ice in the lower part of the image has many deep grooves.

An ice stream can be seen moving northward into the freezing waters off the coast, where many icebergs are floating.

Further north, particularly in the full image, many ripples are visible in the ice. These may actually be “megadunes” of ice.
