Abstract
Variability of the profiles of bioluminescent lighting and chlorophyll a concentration along the coastal zone of the Crimea and its causes are analyzed using the data of two expeditions and satellite data. It is shown that the bioluminescent lighting and chlorophyll a concentration are minimal in a vicinity of the deep-sea cyclonic eddy, where the upwelling occurred and the upper mixed layer depth was as small as 20 m. Minima of bioluminescent lighting and chlorophyll a concentration were observed in the shallow area which is rich in biota.
