Turka, Lviv Region, early XXth century
Rainbow over the Mountains, Turka. L'viv Region, Ukraine by Pavlo Kuzyk on Flickr
A circle of thinned ice on the southern end of Lake Baikal (Russia, April 2009), from the International Space Station. The circle has a diameter of 4.4km.
Usually 5 – 7km in diameter, these mysterious ice circles were first reported in April 1999 near Cape Krestovsky, and assumed to be caused by methane emissions from the basin of the lake. The circles appeared again in April 2003, 2005 and 2008 in the same place, as well as near the settlement of Turka in 2008.
The circles appear in the same locations, often near the Syvatoy Nos peninsula. Here, anticyclonic eddies often occur, with warm water in their centre. This causes the ice to become thinner. The ice is then saturated with water, and sags a little. Cracks appear. and the structure of the ice changes near the circle.
