“…As a result, an analysis of the spreading of specific river plumes under wind forcing requires the examination of the limitations listed above before applying the result of the dependence of deflection angle on latitude. In addition, the obtained results about river plumes are not directly applicable to other substances in the sea surface layer, including oil plumes [33][34][35][36], suspended and floating pollutants [37,38], thermal plumes [39,40], etc., due to significant differences in forces, which govern their spreading dynamics.…”

Wind is the main external force that governs the spreading of river plumes in the sea. Many previous studies demonstrated that the spreading direction of river plumes (especially small plumes) generally coincides with wind direction. At the same time, the majority of river plumes are strongly affected by the Coriolis force, which is also among the baseline knowledge about the plumes. In this study, we focus on the deflection of plumes from wind direction induced by the Coriolis force, which received little attention before. For this purpose, we analyzed an extensive set of Landsat 8 and Sentinel-2 satellite images of multiple small- and medium-sized river plumes at different parts of the World Ocean and synchronous wind reanalysis data. We demonstrated that the deflection angle is stable for individual river plumes for different wind directions, albeit with certain limitations related to wind speed and coastal morphology. Moreover, the deflection angle is similar for river plumes located at similar latitudes and varies from ~0° near the Equator to 15–25° in temperate zones and ~30° in polar zones. Finally, we derived a direct relation between latitude and the deflection angle. The obtained results contribute to our understanding of universal features of river plume dynamics, which is important for monitoring and forecasting of delivery and fate of fluvial water and river-borne matter in different coastal regions of the World Ocean.

“…При этом загрязнение прибрежных акваторий органическими веществами имеет не меньшее значение, зачастую, большие масштабы [Nemirovskaya et al, 2017;Nemirovskaya, Khramtsova, 2021]. В настоящее время вопросами идентификации углеводородов в компонентах окружающей, в том числе и морской среды, занимаются как отечественные специалисты [Nemirovskaya et al, 2022], так и зарубежные [Zhang, Volkma, 2020;Rushdi et al, 2021]. Несмотря на значительное количество публикаций по этому вопросу, проблемы, связанные с органическим загрязнением, в частности, с происхождением углеводородов, освещены недостаточно.…”

The aim of the article is to study the bottom sediments of the coastal zone of Kazantip peninsula in the Sea of Azov of complexes of hydrocarbon pollution. This water area is a site with a high level of recreational load, despite the presence of a nature reserve there, and is also characterized by a rugged coastline, which causes the accumulation of pollution in bottom sediments. The material for the study was samples of the upper layer of bottom sediments, which were taken in the summer of 2021 in the coastal waters of Cape Kazantip (Sea of Azov) with a manual sampler from depths of up to 1.5 m both within the protected area and beyond its borders. Determination of hydrocarbons in bottom sediments was carried out by gas and liquid chromatography in accordance with certified methods. The paper presents new original materials on the distribution of hydrocarbons in bottom sediments in the area of Kazantip peninsula, as well as an assessment of the local level of pollution of marine soils in this area. The ratio of hydrocarbons of different origin in bottom sediments is given. In addition, possible ways and sources of pollution are indicated. As a result of the study, it was shown that the bottom sediments of the coastal zone of Kazantip peninsula are not polluted and the concentrations of the main groups of hydrocarbons are within the range of average values for the Sea of Azov. But, despite this, there are traces of fresh inflows of petroleum hydrocarbons, which can be of both anthropogenic and natural origin.
