A zone of suginarine gas seepages was discovered on the seafloor of the Kamchatsky Gulf (East Kamchatkar, Gas plumes have been detected in the upper part of the Kamchatsky canyon within a depth range of 40-250 m. Sandstones with carbonate cementation were recovered from the seafloor near the seep locations. Cement occurs as calcite and Mg-calcite. the isotopic composition of carbon from carbonates (613C = -62%0 PDB provides grounds for believing that they originate as a result of methane oxidation.
