February 5, 2023 - Persian Gulf

   Persian Gulf

   Clouds of green and tufts of tan colored the waters of the northern
   Persian Gulf in early February 2023. The Moderate Resolution Imaging
   Spectroradiometer (MODIS) on board NASA’s Aqua satellite acquired a
   true-color image of the colorful scene on February 3.

   The various hues are primarily caused by suspended sediment. Much of
   the dirt clouding the water comes from the Shatt al Arab River, which
   enters the Gulf in the north along the Iran-Iraq border. The river
   drains the combined waters of the Euphrates and Tigris Rivers of Iraq
   and the Karun River of Iran. Though other rivers empty into the Persian
   Gulf, the Shatt al Arab carries the most fresh water—and the most
   sediment.

   Sediment appears muddy-tan when it floats near the surface. As it
   sinks, the reflectivity changes with depth, so the muddy hues give way
   to green and finally blue as the sediment disperses. Some of the
   sediment may be remnants of a large dust storm that covered much of the
   Persian Gulf on February 1.
