SOME PECULIARITIES OF FLUORESCENCE DIAGNOSTICS OF PHYTOPLANKTON IN COASTAL WATERS OF THE BLACK SEA

Abstract

Some peculiarities of phytoplankton fluorescence which were observed in coastal waters of the Black Sea (near Gelendzhik) in Aug-Sept 1997, 1998 and 1999 are discussed. Possibilities for the development of a method of water quality bio-indication based on phytoplankton photophysical parameter measurements are reported. A 3-parametric model describing the process of phytoplankton fluorescence formation is considered. Theoretical approximate expressions for generalised parameters are obtained. These expressions indicate the possibility of using generalised parameters for water quality bio-indication.
