      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.
