Patterns in Caspian Sea Sediments and Algae – January 1st, 201238.1N 53.4E
This image focuses on the southeastern shores of the Caspian Sea, the largest enclosed body of water on Earth by area, variously classed as the world’s largest lake or a full-fledged sea. It has a surface area of 371,000 km2 (143,200 sq mi) (not including Garabogazköl Aylagy) and a volume of 78,200 km3 (18,800 cu mi).
It is in an endorheic basin (it has no outflows) and is bounded to the northwest by Russia, to the west by Azerbaijan, to the south by Iran, to the southeast by Turkmenistan, and to the northeast by Kazakhstan. Here, sediments and algal growth cause interesting patterns in the waters near the southeastern shoreline.
