DOI: 10.1002/2016gb005507
Abstract: The extent to which water mass mixing and ocean ventilation contribute to nitrous oxide (N2O) distribution at the scale of oceanic basins is poorly constrained. We used novel N2O and chlorofluorocarbon measurements along with multiparameter… read more here.

DOI: 10.1002/bit.26062
Abstract: Nitrous oxide (N2O), a by‐product of biological nitrogen removal during wastewater treatment, is produced by ammonia‐oxidizing bacteria (AOB) and heterotrophic denitrifying bacteria (HB). Mathematical models are used to predict N2O emissions, often including AOB as… read more here.
