Sedimentogenesis in the White Sea: Vertical Fluxes of Suspended Particulate Matter and Absolute Masses of Bottom Sediments

摘要

A new approach has been applied to studying marine sedimentation using dispersed sedimentary material in sediment traps compared to the surface layer of bottom sediments. Based on long-term studies of a small sea of the Arctic Ocean, it was possible to establish new sedimentary patterns in the conditions of the Subarctic and Arctic zones. The monthly, seasonal, and long-term dynamics of the main components of fluxes of dispersed sedimentary material have been studied. The marine stage of sedimentation of the main components of dispersed sedimentary material over time is discussed; it is shown that the biogenic component of the flux decreases by an order of magnitude when passing from dispersed to concentrated forms. The average values of the vertical fluxes are calculated: the total and those of the contributions of the main biogenic and terrigenous components per 1 m~2 of the bottom and over the entire deep sea area of the White Sea.
