ROLE OF SEISMIC ACTIVITY TO FORM PRESENT-DAY GAS HYDRATE IN THE OKHOTSK SEA

Abstract

In 1988 was found the first a few methane flares in North Sakhalin shelf and slope. It is second period (from 1988 to 1998) to study methane distribution in water column Okhotsk Sea and mostly goal was to study methane fluxes. Every year there were found a new methane bubbles fluxes (flares) from sediment to water column. It appear because seismic-tectonic in west Okhotsk Sea area is activity from 1988 to modern (2007). In area with bubbles methane concentration increased in 100-1000 times as well as bottom water column and surface water.
