Abstract: According to expeditionary and coastal monitoring studies carried out in 2019 and 2020, we analyzed the structure features and temporal variations of colored dissolved organic matter concentration in the Omega Bay field. It is shown that the structure of the analyzed parameter field in the Omega Bay is formed as a result of interactions in the system of local anticyclonic circulation that involves both Sevastopol seaside water, where its concentration is close to the natural normal, and water of the isolated apex part of the bay that experiences anthropogenic pressure. The field under consideration is well stratified in the apex of the bay and is characterized by poorly pronounced vertical stratification in the central and open marine part of the bay. The response to atmospheric and marine processes is traced in the field of colored dissolved organic matter concentration during the summer of 2020. It was revealed that rains and polluted water advection from the sea were accompanied by a noticeable increase in the concentration of the analyzed substance in the beach area of the bay. The opposite effect was observed during upwelling. © 2022, Pleiades Publishing, Ltd.
