Methane-containing sediments, accumulated everywhere along continental margins, are a powerful source of atmospheric methane, the third (after carbon dioxide and water vapors) most significant greenhouse gas. Meanwhile, until recently, scientific literature lacked data on the contribution of arctic continental margins to the formation of the global methane budget, as well as realistic forecast scenarios of future climate changes. The results of five-year-long (2003-2007) biogeochemical studies on the East Siberian shelf, which characterize the main arctic methane sources and reservoirs, including unique shelf gas hydrates, are presented in the article below. The studies were conducted by researchers of the Pacific Institute of Oceanology, RAS Far Eastern Division, with the participation of researchers of the International Arctic Research Center of the University of Alaska, Fairbanks.
