Short summary

The production of N₂O via nitrification and denitrification associated with low-O₂ waters is a major source of oceanic N₂O. We investigated the regulation and dynamics of these processes with respect to O₂ and organic matter inputs. The transcription of the key nitrification gene amoA rapidly responded to changes in O₂ and strongly correlated with N₂O production rates. N₂O production by denitrification was clearly stimulated by organic carbon, implying that its supply controls N₂O production.
