摘要: Climate models predict significant warming in the Arctic 21st century, which will impact functioning of terrestrial and aquatic ecosystems as well alter land-ocean interactions Arctic. Because river discharge nutrient flux integrate large-scale processes, they should be sensitive indicators change, but detection future changes requires knowledge current conditions. Our objective this paper is to evaluate state affairs with respect estimating Ocean from Russian rivers. To end we provide estimates contemporary (1970s–1990s) nitrate, ammonium, phosphate fluxes for 15 large We rely primarily on extensive data archives former Soviet Union Federation compare these values other model predictions. Large discrepancies exist among various estimates. These uncertainties must resolved so that scientific community have reliable calibrate biogeochemical a baseline against judge (either natural or anthropogenic) watershed.
