Perhaps unsurprisingly, these effects were amplified in areas where atmospheric sulfate deposition had been experimentally elevated to begin with.
The relationship between N2O fluxes and NO3 — concentrations is consistent with observations from small streams (Baulch et al. 2011) as well as observed positive relationships between concentrations of N2O and NO3 — in reservoirs (Beaulieu et al. 2015) and in lakes receiving atmospheric nitrogen deposition (McCrackin and Elser 2011).
