Results of complex oceanographic investigations of northwestern part of the Black Sea in the early autumn period are presented. On the basis of hydrooptical characteristics' measurements the data on total
suspended and dissolved organic matters spatial distribution, as well as Danube and Dniester rivers' estuary zones thermohaline structure, was obtained. The factors that determine bio-optical
characteristics' of aquatic environment distribution, taking into account the wind direction and currents system, are estimated.
