Denitrification and the stoichiometry of organic matter degradation in temperate estuarine sediments; seasonal pattern and significance as a nitrogen sink
Lamontagne MG. 1995. Denitrification and the stoichiometry of organic matter degradation in temperate estuarine sediments; seasonal pattern and significance as a nitrogen sink
To determine the removal of regenerated nitrogen by estuarine sediments, we compared sediment N2 fluxes to the stoichiometry of nutrient and O2 fluxes in cores collected in the Childs River, Cape Cod, Massachusetts. The difference between the annual PO4 3 (0.2 mol P m2 yr1) and NH4 (1.6 mol N m2 yr1) flux and the Redfield N : P ratio of 16 suggested an annual deficit of 1.5 mol N m2 yr1. Denitrification predicted from O2 : NH4 flux ratios and measured as N2 flux suggested a nitrogen sink of roughly the same magnitude (1.4 mol N m2 yr1). Denitrification accounted for low N : P ratios of benthic flux a
