Optical and biological research of fluorescence fields in the Black Sea in autumn 2020

The results of hydrological, hydro-optical and biological studies carried out in autumn 2020 near the coast of Crimea during the 114th cruise of the R/V «Professor Vodyanitsky» are presented. Comparison of the vertical profiles of chlorophyll «a» obtained by different methods has been made. A high convergence was revealed between the fluorescent in situ method for determining the concentration of chlorophyll «a» upon excitation in the blue region of the spectrum and the standard biological in vitro method. The necessity of the simultaneous use of both methods for determining the concentration of chlorophyll «a» and its spatial distribution in sea areas is shown.
