Dust Blowing Off Western Sahara Coast

23.6N 15.9W

Mauritania – December 28th, 2012

Dust blows off the coast of Western Sahara and over the Atlantic Ocean. It appears thickest in the upper left corner, beyond the Wad Ad-Dahabnota Peninsula (also known as the Villa Cisneros Peninsula). Research has shown that dust storms are increasing  in the Sahara Desert and that in parts of North Africa, annual dust production has increased tenfold in the last 50 years.

Since dust storms transport large amounts of material for long distances, their increasing frequency could have serious consequences for the environment. Scientists say the deposition of dust could affect climate change, disease transmission and air pollution. One concern is that as dust deposits increase, levels of carbon dioxide in the atmosphere could change, directly affecting temperatures and rainfall.

Canary Islands – December 28th, 2012

Dust blows off the coast of Western Sahara and towards the northwest, over the Atlantic Ocean. Visible through the dust is the Wad Ad-Dahabnota Peninsula, also known as the Villa Cisneros Peninsula while the region was under Spanish colonial rule. The Canary Islands can be seen near the top edge of the image, although the dust does not reach them.

West Africa – December 16th, 2012

Dust blows off the coast of Western Sahara (above) and Mauritania (below), north and south of the green-watered Bay of Arguin. The plume north of the bay blows to the east-northeast, while the one to the south blows east-southeast. Visible in the upper right corner are the Canary Islands, while the Cape Verde Islands can be seen at the lower left. Both archipelagos are fully visible in the full image.

Mauritania – December 4th, 2012

Golden sands from the Sahara Desert blow westward off the coast of Mauritania and the border zone by Western Sahara. Two main plumes can be observed, one north of the green waters of the Bay of Arguin and one to the south of it.

Mauritania – August 26th, 2012

Dust from the Sahara Desert sweeps off the western coast of Africa, mainly along the shoreline of Western Sahara. The dust blows mostly over the Atlantic Ocean towards the southwest, although some reaches near the Canary Islands (above) and the Bay of Arguin (below).
