Scientists have discovered two large deposits of gas hydrates in the Sea of Okhotsk and the Sea of Japan

Scientists from the international expedition discovered two new fields of gas hydrates in the Sea of Okhotsk and the Sea of Japan, also found the highest in the world of underwater stream of bubbles of methane, the head of the expedition, Head of Department of Geology and Geophysics of the Pacific Oceanology Institute, Far Eastern Branch (POI), RAS, Doctor of Geology and Mineralogical Sciences Anatoly Obzhirov.

International expedition on research vessel "Academician Lavrentiev" has gone from Vladivostok to Sakhalin on August 7 to explore and identify new deposits of gas hydrates. First, such studies were also conducted in the Sea of Japan. The expedition — scientists, FEB RAS, eight Japanese and two South Korean specialist. 

"Now we are back to Vladivostok. Expedition was a success. Most important thing is that we have made three discoveries. First is the discovery of a new gas hydrate deposits on the slope of the Kuril Basin in the southern part of the Sea of Okhotsk," — said the source. 
According to him, work in search of gas hydrates were here for the first time. Scientists suggest that the accumulation of gas hydrates here can talk about close oil and gas deposits. A more detailed study of this area will be one of the tasks of such an international expedition that is already scheduled for 2013. 
"A little further south on the same slope of the valley, we found a strong stream of bubbles of methane, the source of which is likely — deposits of gas-bearing rocks. It rises to the surface from a depth of 2.2 thousand meters, so it's the only one in the world so high the torch. For comparison, in second place now stands the flow of methane in the Black Sea, its height — 1,3 thousand meters ", — said the official. 
He said that the third discovery scientists was the discovery of large accumulations of gas hydrates in the Sea of Japan on the western slope of Sakhalin in the Tatar Strait. Work on the study of such deposits were also held here for the first time. 
"The whole province of gas hydrates found in the Tatar Strait, is found immediately 43 of methane. Prior to that, in these areas, searching for oil and gas were carried out only on the shelf. Our discovery — a possible indicator of oil and gas deposits on the side of the strait. Next year we plan to thoroughly examine and this area ", — said Obzhirov. 
Research holds deposits of gas hydrates Institute of Oceanology, Russian Academy of Sciences Far East for several years. At the same time, scientists often find new areas with abnormally high concentrations of methane and gas hydrates. 
Gas hydrates — crystalline compounds formed under certain conditions of temperature and pressure of the water and gas. Gas hydrates resemble compacted snow and can burn. Due to its structure, the unit volume of the gas hydrate can contain up to 160-180 volumes of clean gas, it easily decomposes into water and gas at higher temperatures. 
In the 1960s, Soviet scientists have discovered the first gas hydrate deposits in the north of the USSR. Since then, gas hydrates were considered as a potential source of fuel.
