This dataset represents the results of an oil spill simulation conducted using the Medslik-II Oil Spill Model, focusing on the environmental dynamics of a simulated oil spill event that occurred on March 24, 2019, off the southeastern coast of Brazil in the South Atlantic Ocean. The dataset includes 12 simulations, varying wind drift angles between 10° and 45°, wind drift factor of 1%, 3% and 6% and, incorporating stokes drift, to assess the impact on oil spill trajectory. The dataset includes time-evolving maps of surface oil concentrations, ocean currents, and wind fields, providing a comprehensive view of the spill's transport and dispersion under real-time environmental forcing conditions.

The simulations integrate critical physical processes such as advection, spreading, evaporation, emulsification, and dispersion to model the fate of the spilled oil. It uses the daily Global Ocean Physics Reanalysis product (GLORYS12V1, https://doi.org/10.48670/moi-00021) and the Global Ocean Hourly Reprocessed Sea Surface Wind and Stress from Scatterometer and Model (https://doi.org/10.48670/moi-00185) from the Copernicus Marine Service ensuring realistic environmental conditions. The spill was configured with a total spill rate of 27.97 tons/hour, lasting 4 hours, and an oil type characterized by an API gravity of 22.8. The Lagrangean high-resolution grid (100 m) enables detailed spatial analysis of the oil's distribution over the simulation minimum period of 144 hours (spanning March 24 to March 30, 2019).
