Particulate matter fluxes determined in the area of the NS Komsomolets wreck in different years

The nepheloid layer that provides high horizontal flux of sedimentary material represents the main source of matter for bottom sediments. Vertical particulate matter flux is largely formed in the nepheloid layer; flux from higher layers of the water column is insignificant.

Horizontal and vertical fluxes of sedimentary matter show positive correlation. Matter flux from bottom sediment into the nepheloid layer and residence time of particles in the latter are estimated.
