THE INFLUENCE OF TERRIGENOUS AND BIOGENIC FACTORS ON THE FORMATION OFELEMENT PARTICLE FLUXES OFFSHORE THE SEA OF JAPAN

An attempt is made to clarify the role of biological and lithodynamic factors in the fractionation of the chemical composition of suspended particles relative to sedimentary rocks, based on data on the content of various groups of elements in plankton, particulate matter, and bot tom sediments. The structure of the biogeochemical barrier that contro ls the supply and distribution of matter in the system water-sediment is elucidated by comparison between direct measurements of particulate fluxes of elements (obtained by means of sediment traps) and calculat ions based on different initial data.
