Аннотация: Abstract: The spatiotemporal variability of concentrations and export of inorganic dissolved biogenic elements (nitrogen and phosphorus) in the Yenisei River runoff is assessed. The analysis of changes in phosphate, nitrate, nitrite, and ammonium concentrations in the river water was carried out from the Krasnoyarsk hydroelectric pПоказать полностьюower station tailwater (56° N) to the outlet near Igarka (68° N). The enrichment of the Yenisei water with biogenic substances exported from the Krasnoyarsk Reservoir was found. Among the largest tributaries, the Angara River has the greatest effect on the concentration of inorganic nitrogen and phosphorus in the Yenisei runoff. The spring flood makes the maximum contribution to the annual flux of biogenic elements. The summer-autumn period, despite its duration and significant water discharge, is characterized by the low fluxes of dissolved inorganic nitrogen and phosphorus, which indicates an active participation of biogenic elements in the biogeochemical processes in the Yenisei. © 2022, Pleiades Publishing, Ltd.
