Study of Gas Biogeochemical Parameters of Gaseous Fluids from the Bottom of the Black Sea

摘要

Gaseous fluid flows from sediments into bottom water of seas and oceans attract attention of oceanogra-phers, particularly specialists in gas geochemistry. Fluid flows from the Black Sea bottom were the main study object in Cruise 61 of the R/V Professor Vodya-nitskii, carried out in the Ukrainian segment of the Black Sea in June-July, 2004. The expedition was organized and conducted by the Division of Marine Geology and Sedimentary Ore Formation, National Academy of Sciences of Ukraine. Gas biogeochemical parameters were investigated at the Institute of Oceanology (Moscow). These works were aimed at studying spatial variations in gas biochemical parameters in seawater and bottom sediments in the zone of local fluid flows.
