Three-year biophysical monitoring in the coastal waters of Sevastopol has revealed the characteristic features of the vertical structure and seasonal dynamics of the field intensity of the bioluminescence caused by hydrophysical parameters of environment, as well as variability of quantitative and qualitative characteristics of luminous dinoflagellates. It is shown that there are four types of vertical structure of the field intensity of bioluminescence, coinciding with the seasons of the year in the annual cycle. Each type is characterized by a particular set of dominant species of luminous dinoflagellates, with varying sizes of cells, which, along with the number has been determining the value of their biomass in a given month. Comparison of average values of the bioluminescence field intensity in the layer of 0 – 60 m and their variability showed that in 2009, they were in 2 times, and in 2011, 1.5 times lower than in 2010, when summer was hotter and winter was warmer. A predictive model for calculating biomass luminous algae by bioluminescence intensity was proposed on the basis of the linear regression equation.
