Abstract: In 1989-1991 bottom fluzes of suspended matter were measured in the Black Sea costal zone. Sedimentary traps (mouth area 1194 cm) were placed in 16 points between Novorossiysk and Sochi. These fluxes were found to vary in a wide range (from 0.07 to 10.29 × 10-3 g/ cm2/day) due to non-uniform seasonal distribution of precipitation and due to vortex transport. Terrigeneous suspension is rich in organic matter (Corg = 2.92 % in the average) and more finely dispersed in comparison with bottom sediments accumulated in the areas of sedimentary trap location. The major part of suspension is transported outside the regions under study.
