| Popis: | The causes and features of the variability of the bioluminescence intensity of the plankton community in the spring and autumn periods along the coast of Crimea are analyzed based on expedition and satellite data. It is noted that synoptic and mesoscale vortex processes exert a significant impact on the vertical profile of the bioluminescence intensity in hydrobionts and must be taken into account in the analysis of the seasonal variability of bioluminescence parameters. The concept of integral hydrobiont bioluminescence intensity (IHBI) is introduced; it allows one to estimate the total biomass of hydrobionts inhabiting the depth range under consideration. It is found that the average IHBI in the northern part of the Black Sea in the autumn period is higher than in spring by more than ten times. It is noted that mesoscale vortex formations exert the greatest effect on the IHBI in the region of the continental slope. |
