Special Issue Information

Dear Colleagues,

Efficient oil spill mitigation actions depend on rapid detection of oil slicks and prediction of their fate and displacement. This will allow response agencies time for planning and providing a specific and timely intervention at sea. Oil slick detection can be done in-situ or by remote sensing. Forecasts are usually performed through numerical simulations with the application of empirical and semi-empirical algorithms. Breaking waves and vertical mixing of oil will affect droplet size distribution and horizontal displacement of the oil. In this Special Issue, we would like to focus on applications of high-resolution model setups in combination with fully fledged oil spill simulation models, which includes the most important factors affecting the oil fate. Comparisons with real-world cases are particularly welcome. The contributions should build on the recent rapid development in high-resolution ocean modelling. Coastal applications with features such as complex topography and river plume interaction are of special interest, as well as studies involving new methods for oil slick detection in combination with transport modelling.

The formation of sunken oils is mainly dominated by the interaction between spilled oils and sediments. Due to their patchiness and invisibility, cleaning operations become difficult. As a result, sunken oils may cause long-term and significant damage to marine benthonic organisms. In the present study, a bench experiment was designed and conducted to investigate the quantitative distribution of polycyclic aromatic hydrocarbons (PAHs) in sunken oils in the presence of chemical dispersant and sediment. The oil sinking efficiency (OSE) of 16 priority total PAHs in the sediment phase was analyzed with different dosages of dispersant. The results showed that the synergistic effect of chemical dispersant and sediment promoted the formation of sunken oils, and the content of PAHs partitioned in the sunken oils increased with the increase of dispersant-to-oil ratios (DORs). Furthermore, with the addition of chemical dispersant, due to the solubility and hydrophobicity of individual PAHs, the high molecular weight (HMW) PAHs with 4–6 rings tended to partition to sediment compared with low molecular weight (LMW) PAHs with 2–3 rings. The synergistic effect of chemical dispersant and sediment could enhance the OSE of HMW PAHs in sunken oils, which might subsequently cause certain risks for marine benthonic organisms. Full article
