Surface Oil Spill Simulation and Environmental Dynamics Dataset: The Brazilian P-53 oil spill study case

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).

本数据集收录了采用 medslik-ii 油污泄漏模型进行的油污泄漏模拟结果，旨在分析模拟于 2019 年 3 月 24 日发生于巴西东南沿海、南大西洋地区的油污泄漏事件的生态环境动力学。数据集涵盖了 12 次模拟实验，风漂移角度介于 10° 至 45° 之间，风漂移因子分别为 1%、3% 和 6%，并纳入斯托克斯漂移，以评估其对油污泄漏轨迹的影响。数据集包含了表面油浓度、海洋环流和风场的实时演变图，全面展现了在实时环境强迫条件下的油污传输与扩散情况。模拟过程整合了诸如平流、扩散、蒸发、乳化及分散等关键物理过程，以模拟泄漏油的命运。该模拟采用了每日全球海洋物理再分析产品（GLORYS12v1，https://doi.org/10.48670/moi-00021）以及来自哥白尼海洋服务机构的全球海洋小时级再处理海面风速和应力数据（https://doi.org/10.48670/moi-00185），以确保环境条件的真实性。油污泄漏配置了每小时 27.97 吨的总泄漏速率，持续时长为 4 小时，油品特性表现为 API 密度为 22.8。拉格朗日高分辨率网格（100 米）允许对模拟最小周期内（跨越 2019 年 3 月 24 日至 3 月 30 日）油污分布进行细致的空间分析。
