This paper discusses the application of G03 parameterization to calculate the vertical turbulent diffusion coefficient from vertical profiles of water density and current velocity. The work is based on the processed data obtained in the course of the 95th cruise of the Professor Vodyanitsky research vessel with a depth resolution of about 10 m in the central sector of the northern Black Sea from June 16 to July 4, 2017. Salinity and water temperature profiles were measured using a SBE 911plus probe and current velocity was determined with a LADCP lowered acoustic doppler current profiler. The transfer functions of measured parameters, calculated vertical derivatives at finite increments, and processed data were taken into account when integrating the canonical spectrum of internal waves. The vertical turbulent diffusion coefficient calculated in the main pycnocline on the isopycnal surface with a conditional density of 15 kg/m3 with the maximum buoyancy frequency was considered in detail. Diapycnal mixing was highly intensive in the Black Sea Rim Current. The vertical turbulent diffusion coefficient was 1.3 × 10–6 m2/s at the maximum; in the center and on the periphery of the sea it was 0.4 × 10–6 m2/s and 0.65 × 10–6 m2/s, respectively. The estimated heat, salt, and oxygen fluxes were also the highest in the Rim Current. Fluxes in the center and on the periphery of the sea were 1.5–3 times less than those at the maximum
