Dust Over Bay of Arguin, Mauritania, and Cape Verde Islands

Mauritania – January 6th, 2013

Sahara Desert dust blows off the coast of West Africa. It appears thickest over and near the Bay of Arguin, in Mauritania. Although the image shows the dust only reaching as far as the Cape Verde Islands (lower left quadrant), such clouds of dust are often carried across the Atlantic Ocean by the Trade Winds and tend to reach the Caribbean about a week later, where they may persist in the air for months. Over the northern hemisphere summer, African dust may be carried into higher latitudes and cover large areas of the Gulf of Mexico and the southern and eastern USA. The presence of high concentrations of dust for such long periods of time raises concerns about the impact on human health (click here for more information).
