Concentration, composition and fluxes of dispersed sedimentary matter in the snow-ice cover of the near-pole Arctic region

Abstract

Direct determinations of the dispersed sedimentary matter in the snow-ice cover near the North Pole are carried out. The composition of sedimentary material in the snow-ice cover was studied at the maximum for the high latitudes of the Northern Hemisphere distance from the continents, the vertical fluxes of matter from the under-ice layer were determined. These data were obtained using sediment traps. For snow and ice investigations melt waters of large volume were studied. It was found that dispersed sedimentary matter of aeolian genesis is of primary importance in snow and sea ice.
