Dust Blowing Over Senegal and Mauritania

Mauritania and Senegal - October 27th, 2011

Dust blows over Mauritania (above) and Senegal (below), and off the western coast of the African continent. It is most concentrated in the lower right corner of the image.

Visible north of the cloud of dust is the Bay of Arguin, in Mauritania, green in appearance due to algal growth. Battering surf and shifting sand banks characterize the entire length of the shoreline.

Geographical features of the bay include the Ras Nouadhibou (formerly Cap Blanc) peninsula, which forms Dakhlet Nouadhibou (formerly Lévrier Bay) to the east, is fifty kilometers long and up to thirteen kilometers wide.  Farther south is the coastline’s only significant promontory, seven-meter-high Cape Timiris. From this cape to the marshy area around the mouth of the Senegal River, the coast is regular and marked only by an occasional high dune.

Mauritania - October 4th, 2009

The Coastal Zone, or Sub-Canarian Zone, extends the length of Mauritania’s approximately 754-kilometer-long Atlantic shoreline. Prevailing oceanic trade winds from the Canary Islands modify the influence of the harmattan, producing a humid but temperate climate.

Rainfall here is minimal; in Nouadhibou it averages less than three centimeters annually and occurs between July and September. Battering surf and shifting sand banks characterize the entire length of the shoreline. Here, some dust can be seen blowing southwest off the coast.

One interesting feature of the coastline, visible near the center, is the Ras Nouadhibou (formerly Cap Blanc) peninsula. It forms Dakhlet Nouadhibou (formerly Lévrier Bay) to the east, and is fifty kilometers long and up to thirteen kilometers wide.

The peninsula is administratively divided between Western Sahara (north) and Mauritania (south), with the Mauritanian port and railhead of Nouadhibou located on the eastern shore. Dakhlet Nouadhibou, one of the largest natural harbors on the west coast of Africa, is fortythree kilometers long and thirty-two kilometers wide at its broadest point.
