Blowing out from Libya, a great plume of tan dust floats over the Mediterranean Sea and curls around southern Italy and Sicily. This true-color Aqua MODIS image was acquired on October 3, 2003. Dust blowing out of northern Africa over the Mediterranean occurs rather frequently during the warmer months - April to October - but also occurs occasionally during the colder months, typically once or twice during February.

Airborne dust from the Saharan Desert, which stretches across almost all of North Africa, can have far-reaching effects. Dust from the western end of the Sahara has been known to travel across the Atlantic into the waters of the Caribbean and Gulf of Mexico. The iron-rich dust settles into the water there, and can cause blooms of toxic algae, an event known as a red tide. The dust is also detrimental to the health of coral reefs, and can trigger air pollution alerts.
