The heavily human-perturbed coastal oceans are hotspots of nitrous oxide (N2O) emission to the atmosphere. processes underpinning N2O flux, however, remain poorly understood, leading large uncertainties in assessing global budgets. Using a suite nitrogen isotope labeling experiments, we show that multiple contribute production throughout estuarine-coastal gradient, sustaining intensive flux Unexpectedly, denitrification, rather than ammonia oxidation as previously assumed, constitutes major...
Nitrite, an intermediate product of the oxidation ammonia to nitrate (nitrification), accumulates in upper oceans, forming primary nitrite maximum (PNM). Nitrite concentrations PNM are relatively low western North Pacific subtropical gyre (wNPSG), where eddies frequent and intense. To explain these concentrations, we investigated nitrification cyclonic wNPSG. We detected half-saturation constants (i.e., high substrate affinities) for at 150 200 meter water depth. Eddy-induced displacement...
