ABSTRACT

Natural and anthropogenic event information helped to simulate the physical–chemical behavior of hydrogen sulfide (H₂S) in a deep oil spill and a hypothetical deep-ocean hydrothermal discharge. This research led to the development of the Lagrangian model of the discharge plumes in both cases and also analyzed the profiles of the H₂S concentration at different depths taking into account its dissolution in ocean water and oceanographic conditions, such as thermohaline stratification, current fields, as well as the characteristics of the spilled hydrocarbon and the hydrothermal. The results revealed a first approximation in the identification of the dynamic behavior of the concentration profiles of H₂S as a function of the oceanographic conditions. Hydrogen sulfide concentrations vary between natural and anthropogenic discharges at various depths, leading to a numerical model for applying in chemical oceanography.

摘要

自然和人为事件信息有助于模拟深层石油泄漏和假设的深海热液排放中硫化氢 (H ₂ S)的物理化学行为。这项研究促成了两种情况下排放羽流的拉格朗日模型的发展，并分析了不同深度的 H 2 _S浓度分布，考虑到其在海水中的溶解和海洋学条件，如温盐层结、海流场以及泄漏碳氢化合物和热液的特征。_{结果揭示了 H 2}浓度分布动态行为识别的第一近似值S 是海洋条件的函数。不同深度的自然排放和人为排放的硫化氢浓度各不相同，从而形成了适用于化学海洋学的数值模型。
