   According to the materials of the expedition conducted in December 2018, the structure of the fields of temperature, salinity, pH, total suspended matter (TSM) content, dissolved organic matter (DOM) and the concentration of dissolved petroleum (DP) in еру South and Ship Bays were analyzed. It is shown that the thermohaline structure in the South Bay was determined by the processes of convective mixing, which manifested themselves in different ways in the angular stratified and homogeneous seaward parts of its water area. In the angular part of the bay a well-defined stable vertical stratification of water was observed, which prevented the spread of convective currents into the deeper layer. As a result, the upper thin layer turned out to be the coldest, and throughout the entire water column a well pronounced temperature inversion formed in the angular part. In the seaward part of the South Bay, the water column was uniform vertically.  The north-north-west wind accompanying the survey caused a surge effect and a corresponding compensatory rise of water from the bottom horizons of the angular area of ​​the bay to the surface of its middle part. The waters of the seaward area of ​​the South Bay due to more active dynamic processes were more saturated with the TSM, compared to the waters of its middle and angular parts. The marked excess of the TSM and DOM concentration over their natural norm indicates the presence of suspended matter and dissolved organic matter of anthropogenic origin in the species of the studied water area. Despite the obvious signs of oil pollution observed on the sea surface, it was revealed that in the predominant part of the studied water area, the indicator of water pollution with DP corresponded to the natural norm. The pH on the sea surface everywhere corresponded to its natural rate.

Keywords: temperature, salinity,  pollution, TSM,  DOM,  DP,  pH,  South Bay, Ship Bay, Crimea.
