Dynamics of the main components of fluxes of sedimentary matter in the White Sea

Аннотация

The results of long-term investigations in a small sea of the Arctic Ocean served as a basis for revealing new regularities characteristic of the sedimentary process in the Subarctic and Arctic zones. The monthly, seasonal, and multiyear dynamics of the main components of dispersed sedimentary matter fluxes are analyzed by defining the marine sedimentation stage. It is shown that the biogenic constituent of the flux decreases by an order of magnitude at its transition from dispersed to concentrated forms. The average values of the vertical flux are calculated including the total sedimentary matter and the contribution of main biogenic and terrigenous components per m² of the bottom and the entire deep area of the White Sea.
