The dust that blew through the Sahara Desert the day before continued its journey on June 24, 2012. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite captured this natural-color image on June 24.
The dust blew off the coast of Morocco and over the Atlantic Ocean. Off the coast, the dust formed an arc that bent eastward, in the direction of the Mediterranean Sea. Immediately off the coast of Morocco, just north of the border with Western Sahara, the dust was thick enough to completely hide the water surface below. Dust also blew over the easternmost Canary Islands.
Over Morocco and the Atlantic Ocean, clouds hovered over the dust, partially blocking the satellite sensor’s view of the plumes. The clouds may have been associated with the same weather system that stirred the dust.
Saharan dust hovered over the Atlantic for several days in mid-January 2008. This image shows two different areas of dust plume activity. Immediately off the coasts of Western Sahara and Mauritania, a series of tan dust plumes blow in predominantly straight lines toward the northwest. Farther west, a large, diffuse plume of dust hangs over the Atlantic Ocean
