抄録

An original classification of anomalous methane fields according to the vertical structure of the water column in the Sea of Okhotsk is proposed. Basic types of anomalous methane fields are described: penetrating, near-bottom, deep, intermediate, subsurface, surface, and combined. Anomalous methane concentrations are greater than background values, sometimes by 1-3 orders(up to 30000nl/l above methane hydrates). Spatial and quantitative varieties of anomalous methane fields have genetic relations with different hydrocarbon sources. These varieties suggest a high permeability of active fault zones and geochemical activity in marginal areas, especially along the western Sea of Okhotsk.
