Abstract

This paper discusses a laboratory fluorimeter that has been developed and proposes a technique for quantitatively estimating the fluorescence intensity of dissolved organic matter (FIDOM) that makes it possible to carry out assay measurements and to calibrate the submersible fluorimeters that measure the FIDOM directly aboard ship. Combined profiles of the vertical distribution of the FIDOM, of the density of sea water (SW), and of the fluorescence of phytoplankton chlorophyll are obtained in the depth range 10–125 m in the Black Sea. It is proposed to use a submersible fluorimeter to determine the depth at which a densitydiscontinuity layer of SW occurs directly during vertical probing by the apparatus.
