A team of researchers affiliated with several institutions in Russia and one in France has found a possible explanation for the creation of ice circles in Lake Baikal—the deepest lake in the world. In their paper published in the journal Limnology and Oceanography, the group describes their two-year study of the ice circles and what they learned about them.
Approximately twenty years ago, scientists became aware of ice circles forming in different locations in Lake Baikal in the spring and summer months. The mysterious circles were so large that they…
