The Mystery of These Strange Ice Rings in Siberia is Finally Solved. Since 1969, people have been aware of the formation of strange ice rings in Lake Baikal. However, it is not clear how these strange structures emerged for decades.
In a new study published in the journal Limnology and Oceanography, researchers understood the source of this unique look.
Approximately 25-30 million years old Lake Baikal is one of the oldest lakes in the world and with its depth of 1642 meters, it is the largest freshwater lake in the world.
Lake Baikal in Siberia, Russia contains approximately 23,615.39 cubic meters of fresh water, which is more than the combination of all North American lakes.
Throughout the year, the temperature of the lake varies considerably. In the summer, some areas of the lake’s surface rise to 16 degrees, but the surface freezes from the beginning of January to May.The lake is famous for the amazing ice rings that appear only in winter, which are wide enough to be seen from space.
In fact, thanks to the help of NASA scientists , the mystery of these enormous glasses is finally resolved.
Using data collected from satellites and sensors in the lake, it was discovered that deep vortices below the surface of the frozen lake create a clockwise warm water stream even in cooler months.
The strength of the current is very weak at the center where the ice on the surface is frozen, but the stronger current outside the vortex can dissolve ice and these surprising formations can be seen from above.
Although the rings are beautiful, it can be dangerous for drivers driving along the frozen lake. It is much more difficult to detect the rings at ground level.
The exact cause of this hot deep water vortex formation has not yet been understood and research is underway to try to understand this extraordinary.
The available data suggest that it is likely that ice may form in the autumn months before freezing. For now, this old and huge lake still carries many secrets.
