      The Caspian Sea wins the prize for being the largest closed body on   
      Earth, with a volume estimate at about 78,000 cubic kilometers and   
      spanning a surface area of roughly 146,720 square miles (380,000 square   
      kilometers). That’s a surface area larger than the country of Germany.   
      
      The Caspian Sea is sometimes divided into three parts, ecologically   
      speaking. In the north, the sea is shallow, with a mean depth of only   
      about 32 feet (10 meters), while the central sea deepens to 2,585 feet   
      (788 meters). The deepest part of the Caspian Sea reaches 3,363 feet   
      (1,025 meters) in the southern section.   
      
      Despite the deep water, the southeastern Caspian Sea just off the coast   
      of Turkmenistan hosts a wide area of marine shallows, where the   
      mud-covered bottom lies under a layer of water that stays less than 98   
      feet (30 meters). This coastal shelf stretches 124 miles (200 km) from   
      north to south and 75 miles (120 km) from the shoreline into the sea.   
      Beyond this shelf, the seafloor takes a deep plunge; however, the   
      waters over the shelf are perpetually turbid as the ever-active wind   
      stirs mud and sediment up from the shallows.   
      
      On May 23, 2022, the Moderate Resolution Imaging Spectroradiometer   
      (MODIS) on board NASA’s Terra satellite acquired a true-color image of   
      brightly-colored sediment in the Caspian Sea off of the coast of   
      Turkmenistan. A small bit of the coast of Iran is also visible at the   
      bottom of the image. The gorgeous color lies almost entirely over the   
      shelf of marine shallows located in this section of the of the Caspian   
      Sea.
