Relationship between nitrogen isotope ratios of NO3- and N2O in vertical porewater profiles through a polluted rain-fed peat bog
Original language description
We report a combination of delta15N-NO3- and delta15N-N2O values along vertical porewater profiles through a Sphagnum-dominated, high-elevation peat bog. Our objective was to distinguish between N2O production from NO3- via denitrification and N2O consumption via reduction to N2. Nitrate-N in runoff was isotopically heavier than NO3--N in atmospheric deposition, indicating export of organically-cycled N. Constant N2O concentrations in porewater profiles contrasted with a shift toward higher delta15N-N2O values upward. In the 60-30 cm depth interval, a significant negative correlation between delta15N-NO3- and delta15N-N2O values was observed. Higher delta15N values of residual NO3- in the deepest peat layer reflected higher rates of NO3- reduction. Isotopically heavier N2O-N at shallower depths corresponded to residual N2O following partial reduction to N2.
