“He have nazyvatsya the sea, that mingled with a large sea, and obesity its terms cannot be”, – wrote in the XVII century on lake Baikal Tsar’s Ambassador Nikolay Spafariy. Blue Crescent of lake Baikal have spread from the southwest to the northeast between the mountain ranges of Eastern Siberia by as much as 636 kilometers. In the Central part of the width of the lake over 80 km, and the opposite shore can be seen only in very clear weather, and the depth of Baikal reaches an incredible value for lake – 1637 meters. It is the deepest lake in the world. Photos Of Baikal. of course, to give some indication of the unique nature of the lake, but passed only a fraction of the charm of the sacred sea. You need to see the blue gave the Baikal lake, the mighty cliffs rising from the water straight to the sky, to feel the power of Baikal winds and waves, to understand why the Baikal often called the sea and not a lake.
Tectonic depression in which lies lake Baikal, began to fill with water 20-25 million years, and in its present shape, the lake has existed for several million years. The depth of the fracture in the earth’s crust, in which is situated the Baikal reaches 8.5 km. Most of the fault over millions of years has filled with sediments.
Lake Baikal contains 20% of the world’s fresh water. More than 330 rivers Continue reading
Russia — a country with the vast territory on the planet. The Russian landscape is extremely diverse: there are the steep mountains of the Caucasus, and the great plains of Siberia, and flowering steppes of Kalmykia, and, of course, endless lakes, the water surface which attracts travelers, artists and poets.
Freshwater is huge. Mostly it’s the former glaciers that melted thousands of years ago. The total number of lakes exceeds two million, and their total area is about 350 thousand square kilometers. But not all of them manage to preserve in pristine purity. Human activity most often has a detrimental effect on the state of water reservoirs and their ecosystem. So to see a really clean lake, we have to go there where no human foot has ever stepped.
The first place is rightly given to lake Baikal. It’s not just the biggest lake of Russia, it is the deepest and largest reservoir in the world. 85 per cent of the fresh water of the country is concentrated here. Because of its incredible size, the locals call Baikal the sea. And you only need to see once to understand how vast its expanse.

Lake Kaffeklubben (detsk. Kaffeklubben Sø, 83 37′) is located on a small (48 ha) of the eponymous island. to the North of Greenland, only 707 km from the pole. This is the most Northern lake on the Earth.
For a long time scientists argued about whether to receive life in such places, the impulse to reproduce as a result of nitrate pollution, or make her stop the impending effects of global warming. It seems that an international group of researchers under the guidance of Bianca Perren of the University of Franche-comté (France) managed to answer this question.
Water near the shore Kaffeklubben. No, not the result of a continuous thawing, and only a puddle formed on the surface of thick ice. Nevertheless, diatoms thrive already, for the first time in 2,400 years. (Photo by Bianca Perren et al.)
Despite the harsh living conditions, once the lake was full Kaffeklubben life in the face of cyanobacteria. The ice over the lake while constant, varying only the thickness. But even under 1-2 m of ice cyanobacteria survive. However, they are most active in summer when the air temperature above the ice reservoir is as high as +1,6 C. But more complex forms of life here. But now, but once…
3 500 years ago, when the lake had just been formed, it occupied several Continue reading
