We estimated the possibility of application of satellite data on chlorophyll a concentration to study the variability of the content of suspended organic matter (SOM) components in the surface layer of the Black Sea. The results of simultaneous shipboard and satellite (CZCS and SeaWiFS color scanners) observations of the chlorophyll a concentration which were carried out in different seasons in va­rious areas of the Black Sea deepwater and shelf parts are compared. A high correlation between these concentrations and their similar values (a 5–20 % difference) indicates a good agreement between the measured and calculated concentrations of chlorophyll a. Based on the archive data on the content of the SOM components (suspended organic carbon, nitrogen and phosphorus) and shipboard measurements of the chlorophyll a concentration, the seasonal regression equations were obtained between the simultaneously measured values in the surface layer of the deepwater and northwestern (shelf) parts of the sea. Seasonal concentrations of the SOM components in the surface layer of the northwestern and western deep sea parts are calculated with the use of these equations and available array of satellite data on the chlorophyll a concentration. Examples of their application for studying the spatial and interannual variability of the concentration of the SOM components are given.
Keywords: the chlorophyll a concentration, suspended organic matter, onboard and satellite observations, regression equations, correlation, the Black Sea
