Fauna of the Kara sea are threatened by global warming, and fresh water from the great Siberian rivers. To such a sensational conclusion was made by Russian oceanographers. Scientists have completed the expedition one of the goals is to find out how dangerous radioactive disposal at the bottom of the sea.
Underwater robot slides along the hull of the nuclear submarine. A huge submarine lies on the bottom of one of the bays of the Novaya Zemlya archipelago. She was buried here in 1982 after a reactor accident. Since then, scientists every year to check radiation background. The spectrometer shows: all OK. Not only the submarine, but also a huge number of spent nuclear fuel in the sarcophagus lies at the bottom of the Kara sea. When there were no other methods of disposal, these lifeless water most of the year covered with ice, was considered a suitable place for burial. But for 40 years the Arctic sea ice was 2 times less. Global warming opens up prospects for the Northern sea route. Oceanographers wounds proved that the radiation point of view it is safe. 82 scientists on the vessel "Academician Keldysh" conducted thousands of tests, confirmed the absolute integrity of all the graves and identified under what weather conditions the containers can be lifted from the seabed without risk of damage. Scientists also refuted foreign colleagues that the poverty of the flora and fauna of the Kara sea may be related to pollution.
Sensational conclusion: life is to kill him fresh water. Tens of millions of tons per year enters the sea from rivers Ob and Yenisei. To meet with the Arctic and its inhabitants oceanographers wounds are sent for 10 years in a row. We take hundreds of samples of water, soil and ice, analyzing the composition of air. During this time, the boundary of glaciation in summer, retreated to 800 km, but climate change had virtually no effect on the ecosystem of the Arctic shelf. Scientists have unraveled the mystery and found several unique natural areas, which is supported by the usual ecological balance.
Marine areas of particular importance mapped the Arctic. Now, researchers at Russian Academy of Sciences will be encouraged to give these areas the status of protected areas.
