On the basis of field studies executed in May 2008, we performed the analysis of the distribution of silicon in waters of the Sevastopol Bay under conditions of the formation of a seasonal thermocline. We discuss differences in the distributions of silicon in the surface and bottom layers, including the zone of mixing of river and sea waters. We noticed a significant difference in values of the coefficients of correlation between the concentration of silicon and the salinity for the surface and bottom layers. For bottom layer, we obtain large values of the coefficients of correlation between the concentration of silicon and other hydrochemical characteristics which are explained by the influence of the processes of transformation of organic substance.
