Clouds by Bay of Arguin, Mauritania20.1N 16.5W
Clouds hug the coast of Mauritania near the Bay of Arguin. Green algae can be observed in the northern part of the bay that is not cloud-covered.
Upon opening the full image, the Richat Structure can be observed in the Sahara Desert to the east of the bay. It has a bullseye-like appearance. Although it looks similar to a crater from a meteorite impact, it is actually thought to be a symmetrical uplift (circular anticline or dome) that has been laid bare by erosion.
