The picture of this amazing astronaut depicts a series of milky rotors, the largest “soda lake” on the earth in the waters of the Turkish lake van. Although rotation looks like a common natural phenomenon, they are really less.
Lake Van is the largest lake in Turkey, with a surface of about 1, 1200 square miles (3,100 square kilometers), slightly smaller than the Rhod island. Its surface is located at a height of 5,380 feet (1,640 meters) from the sea and is close to 10, which is extremely alkaline.
The aforementioned photo depicts a part of the lake van around the city of Ericki, located along the northern coast of the lake. The rotation in the image looks very similar Shapes that appear during algal blumWhen rapidly multiply placon species is trapped in air -powered streams. However, this was not the cause of these roaming.
Instead, the milk content in the lake is mostly made of calcium carbonate, as well as the small concentration of derivatives – waste organic material is excluded from living and dead animals. NASA’s Earth Observatory.
The clouds of materials that rotate in this milk are known as “tribidity plus” that are dynamic due to natural or human -born problems on the lake’s floor. It is more likely to appear in this part of the lake as the water level is lower than the rest of the lake, which reaches a depth of 1,450 feet (450 meters).

Lake Wan also has a high-ranking “microbilate”, which is a combination of freeflowing argano-seidiatry structures formed by various germs, stabbing, binding and raining. Microbial Production on Peaks in Spring and Autumn, when microbial communities hit. However, according to the Earth’s Observatory, it is not considered the cause of these particular rotation.
The lake’s high pH level is caused by the high number of carbonate salts, which is ready over time because the lake is “endorak”, meaning it has no shop. Therefore, as the lake produces water vapors, the concentration of salts increases.
The salt concentration in the lake is so high that the water is rarely frozen, though its temperature often falls below 32 degrees Fahrenheit (0 degrees Celsius) in the winter months.
In the last 600,000 years, the water level of Lake Wan has changed significantly as the climate change has changed the water input and vapor rates. A 2014 studies It is estimated that during this time it has fluctuated about 2,000 2,000 feet (600 meters).
Although the large milk rotation in the picture is not due to the algal blum, you can see the small concentration of photoplaunkton that has been accumulated along the coast of the Erickin, as well as inside a small lake near the upper part of the picture.
