IRKUTSK (East Siberia), May 18 (RIA Novosti) - The second stage of an expedition to explore the bottom of East Siberia's Lake Baikal will begin on June 15, a Russian government official said on Monday.
The study of the world's largest and deepest freshwater lake, involving two mini-subs, started last year. The Mir-1 and the Mir-2 mini-subs conducted 52 dives during the first stage last summer, making a number of significant scientific discoveries.
The second stage of a $7.5-mln project envisions over 100 deep-water dives this year, the official said.
Baikal has not been studied completely and many questions still remain unanswered, including the origins of the lake and the unique organisms that live in it.
Scientists estimate Baikal is some 25 million years old. During the first stage of the study, researchers took samples of the oil that seeps through cracks in the lake's bedrock and is digested by the lake's organisms.
In addition, the mini-subs also searched for sacks of gold taken from the Imperial Russian reserves by the White Army's Admiral Alexander Kolchak before he fled from the Bolsheviks across the lake from in the winter of 1919-1920.
Some of the White Army officers reputedly froze on the ice as temperatures dropped to 60 degrees Celsius below zero, and the gold is thought to have sunk when the spring thaw came. However, no treasure, except boxes containing ammunition dating back to the 1920s, has yet been discovered.
Lake Baikal, a UNESCO World Heritage site, holds around 20% of the planet's freshwater.
The Baikal pulp mill, which produces 200,000 metric tons of pulp and 12,000 metric tons of paper per year, has discharged large volumes of toxic waste into the lake since it was built in the 1960s.
The causes, which lead to the appearance of circles on the ice of the lake, have not been studied thoroughly yet. Experts presume that they can be connected with emissions of natural gas from Baikal’s sedimentary strata.
From the geological point of view, Lake Baikal is a graben lake, a piece of the Earth’s crust, limited with steep clefts and attached to a rift zone. Rifts are characterized by an increased thermal flux and seismic activity. High temperature causes an intense generation of gas. Emissions of natural gas from the lake bottom can be observed in summer owing to bubbles rising to the surface and in winter due to unfrozen patches of water with diameter from half a meter to hundreds of meters.
“Dark circles on Baikal’s lake are too big. Emissions are likely to be connected with seismic activity and tectonic changes in Baikal’s rift system”, the site quotes the opinion of experts from the Russian Geological Foundation.

Ok guys come on, this is intuitively obvious to the most casual observer. They are giant drains like you find in bathtubs.
On a serious note very interesting formations to say the least. Would a small fissure releasing warm magma or gasses cause this?
