The Deepwater Horizon accident discharged a staggering amount of oil (about 780,000 kL) into the Gulf of Mexico. In other forecast simulations based on the ocean-only models, spilled oil reached the Atlantic Ocean via the Gulf Stream. In this study, the authors simulated 3-dimensional movement of oils using real-time oceanic and atmospheric conditions obtained by the coupled MSSG (Multi-Scale Simulator for the Geoenvironment) model. Our simulation shows that the amount of oil discharge into the Atlantic is very limited due to the trade winds. The atmospheric coupling to the ocean model is essential in the forecast simulation of spilled oils.
