The ratio between the dispersal of living phytoplankton and the dissolved organic matter (DOM) in the Black Sea waters was investigated by use of a fluorimetric method. The possibility that DOM appears in sea medium as a result of extracellular excretion due to phytoplankton vital functions was studied. However, data obtained during the tests make us to consider an alternative mechanism of DOM appearance in the sea medium.
