Mauritania - January 22nd, 2011

The Bay of Arguin, in Mauritania, appears bright green due to phytoplankton growth. It is south of Cap Blanc, north of Cap Timiris, and contains the islands of Arguin and Tidra. The land to the east is covered by the Sahara Desert.

In the full image, the bulls-eye shaped Richat Structure can be seen to the northeast. Initially thought to be the result of a meteorite impact, scientists now believe it is a symmetrical uplift (circular anticline or dome) laid bare by erosion.
