    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.
