The bioluminescence field as an indicator of the spatial structure and physiological state of the planktonic community at the mediterranean sea basin

摘要

The prupose of this work is to show the possibilities of using the characteristics of the bioluminescent fields monitor the marine planktonic communities. The data bank contains 3500 vertical casts of bioluminecsent potential and near 1000 samples of the planktonic organisms obtained at 500 oceanographic stations executed in 21 expedition to the Mediterranean Sea basin in 1970-1995.Studies were carrried in different seasons in the Mediterranean and the Black Seas where different trophic conditions and considerably different spccis composition and aboundance occurred in the phytoplankton. There are of couuse differences between abundance of various dinoflagellates and an intensity of measurement of bioluminescence, but the main features of these appcared to be similar, the intensity of bioluminescence increased in proportion to their number and physiological state.
