Biooceanographic Characteristics of the Bioluminescence Fields in the Sevastopol Coastal Waters: Results of Long-Term Monitoring

Abstract

Global warming, which certainly covered the Black Sea, caused serious structural and functional changes in the pelagic community, effecting marine bioluminescence, which is an expressive indicator of the environment state. A large number of intensely luminescent warm-water ctenophores-invaders appeared in the surface layer, which increased the total plankton luminescence. Their contribution to the total luminosity of the coastal waters has been poorly studied so far. In practical terms, it resulted in changing of unmasking luminosity of any moving objects in the water column. On the other hand, developing of more sensitive methods for monitoring changes in the marine environment state has become possible.
