A modeling study of oceanic nitrous oxide during the Younger Dryas cold period ...
The marine production, cycling, and air-sea gas exchange of nitrous oxide (N2O) are simulated in a coupled climate-biogeochemical model of reduced complexity. The model gives a good representation of the large-scale features of the observed oceanic N2O distribution and emissions to the atmosphere. T...
