26.09.11.Uchastniki Russian-American expedition to the Eastern sector of the Arctic have found new large fields of methane in the northern parts of the Laptev Sea and the Bering Sea.
This was said by telephone from aboard the research vessel "Academician Lavrentiev" head of the expedition Arctic Research Laboratory Pacific Oceanological Institute, Far Eastern Branch of the Russian Academy of Sciences, a professor at American University of Alaska-Fairbanks Igor Semiletov.
"Gas torches" pass through the entire thickness of the ocean water and thus methane into the atmosphere. Presumably, this is the origin of the deep gas "- quoted Semiletova ITAR-TASS.
Scientists have yet to determine the amount emitted from the depths of the Arctic seas of methane into the atmosphere, which will shed light on its origin.
"Maybe he gets into the sea from the depths of the earth's crust, which may indicate an increase in seismic activity in the region. According to the observations of scientists, the signs of global warming are seen everywhere in the Arctic. Dramatically increased the number of storm days, and the water temperature is unusually high for this time of year. Now the water in the seas, plus three degrees. This means that the formation of ice will slow, and the area of multi-year ice in the Arctic re-cut "- told seven years.
The expedition set out from Vladivostok in early September. It is attended by 28 scientists from Russia and the U.S.. In addition to the staff of the Far Eastern Branch of the Russian Academy of Sciences, are scientists Research Center of Alaska-Fairbanks and the University of Georgia in the U.S..
Funding for the research carried out by the Russian Foundation for Basic Research, U.S. National Science Foundation and the National Endowment U.S. National Oceanic and Atmospheric Administration.
To conduct research on the vessel "Academician Lavrentiev" deployed modern Geophysical complex, which will determine the amount released into the atmosphere of greenhouse gases.
Within 45 days of the expedition scientists to study methane and subsea permafrost areas in the Chukchi, Bering and East Siberian Sea and the Laptev Sea. The expedition has already passed half of the route. It — five thousand miles, of which 1000 — with a comprehensive study.
Far scientists together with their American colleagues over a number of years doing research of methane emissions in the Arctic. Previous expeditions suggest that this greenhouse gas appears in the destruction of underwater sites of permafrost due to climate change, which further enhances the warming and lead to new releases of methane.
These studies have shown that large methane emissions in the Arctic could have disastrous consequences for the Earth's climate.
