Title

Numerical study of oil spilled behavior under ice–covered area

Abstract

The Recent demands of commercial shipping through the Arctic and exploit of natural resources increase the risk of an oil spill in the Arctic Ocean. State-of-the-art modeling techniques are necessary for prevention measures and oil response and determine the fate and effect of oil in the environments. So we developed a numerical simulation model for spilled oil forecasting under ice-covered areas. This simulation model can perform high-resolution computations at low computational cost. Numerical model results of oil spreading over open water, under fully ice-covered water, and under a broken ice field are agreed reasonably well with the previous experimental results. Results of oil spilled behavior under the ice-covered area in the East Siberian Sea have shown the possibility of establishing an accurate and practical forecast system for oil spreading under a marginal ice covers.

Model Characteristics

The oil diffusion model is coupled with the ice-ocean coupled model (IcePOM model). The ocean forcing and sea ice effect is given as a boundary conditions to the oil diffusion model. The atmospheric forcing component is given by ERA-interim reanalysis 6-hourly dataset. The weathering effect is not considered in the current version. The model domain contains the East Siberian Sea. The horizontal resolution is 2.5 km, and there are 217 × 194 grid points. Vertical diffusion of oil on ice covered area is defined on four stages. The forecast period of oil spill is 10-day to 15-day with 30 ensemble members. Data output frequency is 3-hr.

Abstract (Brief description of the experiment contents (initial conditions, boundary conditions, etc.))
The oil diffusion model is coupled with the ice-ocean coupled model (IcePOM model). The ocean forcing and sea ice effect is given as a boundary conditions to the oil diffusion model using one-way nesting. The atmospheric forcing component is given by ERA-interim reanalysis 6-hourly dataset. The weathering effect is not considered in the current version. The model domain contains the East Siberian Sea. The horizontal resolution is 2.5 km, and there are 217 × 194 grid points. Vertical diffusion of oil on ice covered area is defined on four stages. The forecast period of oil spill is 10-day to 15-day with 30 ensemble members.
