On February 10, 2007, a dust plume lingered over the Arabian Sea. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite took this picture the same day. This image shows the horseshoe-shaped dust plume hanging over the ocean, just east of the coast of Oman. Although the source of this dust plume is not immediately obvious, the dust likely blew off the coasts of Pakistan and Iran. A close examination of the high-resolution imagery reveals small tendrils of dust linking those coasts and the larger plume.
