Multiple dust plumes blew off the coasts of Iran and Pakistan on
November 29, 2012. The Moderate Resolution Imaging
Spectroradiometer (MODIS)
on NASA’s Terra satellite
observed the dust plumes in the morning, and MODIS on the Aqua satellite observed the plumes in the
afternoon.
These images document the movement of the plumes southward over
the Arabian Sea. The plumes apparently arose from fine sediments near the
coast. Some of the plumes were thick enough to hide the water surface below,
especially two large plumes off the coast of Pakistan. On the afternoon of
November 29, those plumes fanned out over the ocean water.
Sand seas, saltpans, and impermanent rivers in this region
provide sediments that can easily be lofted into the air. The southern coasts
of Pakistan and Iran rank among the world’s leading dust-producing regions.
