The American aerospace agency NASA published a photo of an abnormal process in the Caspian Sea, called “milky swirls.”

The picture was taken on January 9 by the MODIS spectroradiometer from the Terra spacecraft.

According to the source, surface winds help mix the water and stir up bottom sediments that impart a milky color.

Scientists intend to investigate this phenomenon in order to exclude its negative impact on fishing.

According to NASA, satellite data is a key method of monitoring the Caspian Sea.
