Image Caption: The hyperarid western extremity of the Sahara Desert of Mauritania (19.0N, 15.0W). The foreground is dominated by a series of dramatic, elongated linear dunes and the richat depression. Desert winds regularly blow desert sand towards the coast parallel with the dunes and much of it is actually blown out to sea. Dust storms often move hundreds of miles out into the Atlantic Ocean, sometimes even reaching South America and the Caribbean.
