Abstract

The results of hydro-hydro-optical measurements performed in the spring of 2019 in the northern part of the Black Sea off the coast of the Crimea and the Caucasus are presented. It is shown that the maximum concentration of total suspended matter was observed off the coast of the Kerch Peninsula and in the Feodosiya Gulf, which was associated with the coastal transport of the Rim Current of freshened and turbid Azov Sea waters from the Kerch Strait. Minimums of the concentration of total suspended matter were observed at the southern boundary of the polygon in the area of the cyclonic gyre identified by the survey data, and in the southwestern part of the polygon, where the cyclonic meander was recorded. In the vertical structure of the concentration of total suspended matter in the upper 200-meter layer, three main maximums were observed, the depth of which is associated with the features of the circulation and thermohaline waters structure. One maximum was observed in the layer of seasonal thermocline and pycnocline in the eastern part of the polygon. The second maximum was traced below the cold intermediate layer core in the layer of the main pycnocline and halocline in the central part of the polygon at stations located on the periphery of the cyclonic gyre. The third maximum was found in the entire area of the polygon under the main pycnocline and halocline in the sub-oxygen zone.
