Abstract—The first results of studies of vertical fluxes of sediment particles using the sediment traps at the Trans-
Caspian section are presented. The flux values and distribution regularities are established. The fluxes of particles
forming the sediment are also determined. The intra-annual variability in the fluxes corresponds to the seasonal vari-
ability of the biological activity. Above the northern slope of the Derbent Basin, the maximum vertical fluxes are
recorded in the winter, which is caused by the intensification of the near-bottom currents.
