Abstract
The geographic and bathymetric distribution of siboglinids in the Sea of Okhotsk was studied. At least 75% of all siboglinid findings were at a depth up to 400 m. Most of them were concentrated in the northwestern part of the shelf. Comparison of the data on siboglinid distribution in the Sea of Okhotsk and the aggregate geological data on hydrocarbon distribution showed that, in the Sea of Okhotsk, siboglinids were mostly in the regions of hydrocarbon manifestations, but they were absent in the central areas with the minimum methane and hydrocarbon concentrations in both benthic sediments and the uppermost water layers.
