Quantitative models are developed to describe three different profiles of nitrate observed in the porewater of pelagic sediments: nitrification only is observed; a surficial zone of nitrification is underlain by a zone of denitrification; the zone of nitrification is underlain by a zone of no reaction and then a zone of denitrification. Oxygen consumption and nitrate re duction are assumed to be first‐order processes. by fitting the models to observed [NO 3 − ] profiles, we have estimated benthic nitrate and oxygen fluxes, denitrification rates, first‐order rates constants for O 2 , organic matter, and NO 3 − consumption, and the stoichiometric ratio d [NO 3 − ]: d [O 2 ].
