We report several negative carbon stable isotope excursions in benthic foraminifera in a gas-bearing core LV50-05, collected from an area of active methane venting on the Eastern Slope of Sakhalin Island, the Okhotsk Sea. Within the study area, four methane events (ME) are established in Holocene: short-term ME-1 (700-900 yr BP) and ME-2 (from 1200 to 1400 yr BP), long-term ME-3 (2500-4700 yr BP) and ME-4 (7400-10000 yr BP).
