| Abstract: | A hydroecological model is used for simultaneous studying water pollution processes by petroleum hydrocarbons and their decay
under the oceanographic conditions of Tatar Strait. The model calculations were based on long-term averaged observational
data on interannual variations of water temperature, light intensity, and transparency. Some oceanographic characteristics
of the strait were reconstructed with the help of GIS “Sakhalin Shelf.” The strait’s water area was divided into three regions,
and water exchange between them and the neighboring regions of the Sea of Japan was estimated by a hydrodynamic model. The
results of the study made it possible to assess interannual variations in the concentrations and inner fluxes of petroleum
hydrocarbons, oil-oxidizing bacteria biomasses, and the characteristics of their oxidation activity. |
