Scientists from Russia, Germany, Switzerland and England are looking at the bottom of lake Baikal responses to questions about how life evolved and changed the climate of Central Asia millions of years ago. Using a special sampler researchers get samples of soil from the bottom of the biggest and purest lake on the planet and build the first conclusions and hypotheses.
With augers or chainsaw scientists know better than a professional fisherman. A few seconds and the surface begins to rise the purest Baikal water. The deepest lake on the planet researchers from Russia, Germany, Switzerland and England, as «our laboratory».
Using a special sampler and a conventional winch, the scientists take samples of soil from the bottom of lake Baikal, which today is the main subject of study. The sediments are a unique archive. According to experts, they can store the entire history of Central Asia. They cover everything from earthquakes to the smallest details of appearance and disappearance of species. Professor of Irkutsk state University Nikolay Budnev explains: «In bottom sediments can be found even pollen, which lived here thousands of years ago, and that Continue reading
Baikal and freshwater
Where is the largest freshwater supply in the world? Most are familiar with the geography and ecology of the people will answer without hesitation — the largest source of fresh water in the world is lake Baikal . located in Eastern Siberia.
How much fresh water in Baikal? In the lake Baikal fresh water is contained in very large quantities. The volume of fresh water of lake Baikal is so large, accounting for about twenty percent from the total of all fresh water reserves in the world (up to twenty km3). If to take separately only the Russian reserves of fresh water, lake Baikal is up to 90 percent of their number.
The origin of lake Baikal.
Baikal is not only the deepest lake on the planet (the maximum depth is more than 1,600 meters ), but also the oldest. Estimated age of lake Baikal is estimated at more than twenty million years.
It is considered that lake Baikal was formed in the Wake of a major tectonic fault in the process of continental movements. This theory is confirmed by the fact that volcanic activity in the lake continues to this day — occasionally there are earthquakes in the vicinity of lake Baikal.
Why is the Baikal water is fresh?
The filling of lake Baikal water was due to surface water. Those rivers that flow into lake Baikal, very slightly saline, Continue reading
