Sivash Lagoons - Crimea

This network of lagoons is known as Sivash (also Syvash or Siva ). During the summer months, the warmed marsh waters give off unpleasant odors, lending the region the nicknames of "Rotten Sea" or "Putrid Sea."The shallow waters and varied chemical composition of the Sivash lagoons contribute to their unearthly colors of peach, mustard, lime green, blue, blue-green, beige, and brown. Thick layers of silt coat the bottoms of the shallow marshes, which are rich enough in mineral salts to supply a local chemical plant. Image taken from the international space station in june 2018
