Based on the expedition data in August 2019, the current local system and the structure of the concentration fields of total suspended matter (TSM) and dissolved organic matter (DOM) in the Sevastopol seaside area near Abramova and Omega bays are considered. It is revealed that one of the significant factors that determine the structure of the fields under consideration is the wind surge. Under the influence of the north wind surge, a coastal wind current oriented to the southwest was observed in the studied area of the Sevastopol coast. Its speed in the upper and middle layers varied from 15 to 40 cm/s and from 10 to 15 cm/s at the bottom. The branch of this stream directed to Omega bay, interacting with the bottom raising located in its central part, contributed to the formation of the anticyclone eddy water circulation. This eddy formation appears to be stable in time with the northern quarter winds. Signs that confirm the anticyclone nature of the local water circulation in Omega Bay, as well as the typical coastal current system generated by the wind surge, were found in the structure of the concentration fields of TSM and DOM. It is shown that in the kut part of Omega Bay, in the fields of TSM and DOM content, there is a well-defined frontal zone.
