   Based on the materials of the expedition conducted in November 2019, the thermohaline structure and total suspended matter (TSM) content, dissolved organic matter (DOM), concentration of dissolved petroleum (DP) and pH in the water of the Kamyshovaya bay are analyzed. Topographic cyclonic formations were found in this region, in the inner region of which there were TSM, DOM, and dissolved petroleum (DP). It is shown that the thermohaline structure in the Kamyshovaya bay was determined by convective mixing processes, which manifested themselves in different ways both in the kut stratified and the homogeneous sea part of its water area. In the kut part of the bay, a stable vertical stratification of water was observed, which prevented the propagation of convective currents into the deeper layer. As a result, a well pronounced temperature inversion with an increment of 0.2–0.3 ° С was formed in the water column in the kut part. In the sea part of the Kamyshovaya bay, the water column was homogeneous along the vertical. The vertical stratification of the TSM and DOM content fields in the sea part of the bay resulting from convective mixing was weakly expressed. Dissolved oil products were found throughout the water area. In the kut part, where convection is weakened by the stratification of the halin field, the fields of these elements, especially DOM, were stratified. In the upper freshened layer, the maximum concentration of SIR and DOM was observed. The hydrogen pH on the surface of the Kamyshovaya bay corresponded to the interval of its values typical for the upper layer of the Black Sea waters. It seems likely that in the central part near the western shore of the Kamyshovaya bay there is a natural source of fresh water.

Keywords: temperature, salinity, total suspended matter, dissolved organic matter, petroleum products, pH, Kamyshovaya bay, Crimea.
