Nitrous Oxide Fluxes in Three Experimental Boreal Forest Reservoirs

摘要: Global atmospheric concentrations of nitrous oxide (N2O), a powerful greenhouse gas, continue to increase. While many sources and sinks have been identified, there is little known about how existing newly constructed reservoirs, such as those created for hydroelectric production, impact current N2O concentrations. We hypothesized that fluxes the atmosphere would increase because enhanced nutrient availability increased soil respiration following flooding soils during reservoir creation favor denitrification. Furthermore, we emissions be linked amount organic carbon contained in flooded landscape. These hypotheses were tested by creating three experimental reservoirs over boreal upland subcatchments ranged stored vegetation. Diffusive surface within each estimated using water thin boundary layer method. Surface fluxes...
