... (Boetius, Wenzhöfer, 2013). The upward flows of hydrogen and acetate, as well as of methane and other hydrocarbons, forming in the depth of sediments entrain their microscopic dwellers to the upper horizons (Hubert et al. , 2009). Deepwater drilling on Lake Baikal was done under the Baikal-Drilling international program involving Russian, American and Japanese researchers. In 1993, the first 100-meter hole was drilled near the Buguldeika closing dike, and three years later drilling in the lake sediments ...

Why Does the Cleaner of Lake Baikal Need Dental Crowns?

A tiny copepod—Epishura baicalensis—is one of the most well-known Baikal endemics. This dominant zooplankton species of Lake Baikal is a critical element in the food pyramid of the freshwater ocean. It feeds on bacteria and unicellular algae and is itself food for the Baikal omul and other pelagic fish. This copepod is capable of filtering about one cup of water per day,...

Invisible Guards of Baikal

Being the largest fresh water lake in the world, Baikal is unique not only because of its size and depth but also because of its strikingly clear water. At the same time, several tons of oil rise to the surface of the lake from its deep water deposits every year. However, the oil contamination does not spread over the whole lake, which attests to the fact that there exist special natural purification mechanisms. It is done by specific bacteria using oil carbohydrates as their food substrate. Such...

Young Оil of Baikal

In recent years several academic institutions have actively studied the oil sampled from the surface and water body of Lake Baikal. In 2008 oil samples were taken from the bottom of the lake for the first time. The nature of the oil has been discussed since the 1930s. The oils were found to contain a unique set of hydrocarbons—biomolecules mostly typical of lipids of ...

Lake Baikal occupies the deepest rift basin in the center of the Baikal rift system that initiated after the India/Eurasia collision about 40 Myr ago. The lake consists of the three sub-basins: the shallowest (~900 m) North Baikal basin, the deepest (1634 ...

Glorious Baikal... The Omul Barrel

... ichtyologists? Lyubov Sukhanova is a true ‘blue blood’, ichthyologist in the third (!) degree. Her mother’s parents were ichthyologists; her father’s father was an amateur fisher. After graduating from a university in Kaliningrad, her parents moved to Lake Baikal. Since then, for almost 40 years they have been studying Baikal omul. Thus, her love for science and Baikal Lyubov inherited from her parents, it has been ‘imprinted in her genes’. The depths of Lake Baikal keep many mysteries. Being ...

The Diversity of Crustacea in Baikal

The point is that the species is stenobiontic, i.e. is tightly bound to Lake Baikal’s ‘core’, and is not characteristic of the littoral zone. As to the niche of the biotope, the echo sounding of the water column in the Barguzin Bay and Maloye More demonstrated that the depth close to 100 m limits the aggregations of ...

Ice as the Keeper of Life

For ages man has perceived the kingdom of ice as a lifeless world, world of white muteness and thickened time. The North looks exactly as in children’s fairy-tale about Kai and Gerda. We visualize winter as the time when nature goes to sleep and plunges into dreams until spring comes. But is that really the case? Maybe a splinter of the magic glass of the Snow Queen prevents us from seeing the reality in its true light? Until recently biological science has shown little interest in the search...
