Purpose. The study is aimed at assessing the parameters of vertical turbulent mixing in the main pycnocline of the Black Sea based on the data on current velocity and density measured by standard hydrological instruments. Methods and Results. The data collected during six summer cruises of R/V Professor Vodyanitsky in the central sector of the northern sea area in 2016-2021 were used in the research. Temperature, salinity and current velocity profiles were measured by the CTD/LADCP probes. The vertical turbulent diffusion coefficient was calculated with the G03 parameterization. The applied relations are given. The values of the required parameters on the isopycnal surface with the conditional density value 15 kg/m3 are used as the initial data. Their filtered dependencies on its depth are substituted into the calculated relations. It is found that a well-pronounced maximum of specific kinetic energy is observed on average when the isopycnal depth is 77 m...
