Denitrification in urban river sediment and the contribution to total nitrogen reduction
Ecological Indicators, 2021 Streams and rivers, especially in urban areas, are substantial sinks of bioavailable nitrogen owing to their hydrological connections with terrestrial systems and the intensity of inputs mediated by human activities.

A method for estimating the extent of denitrification of Arctic polar vortex air from tracer-tracer scatter plots [PDF]
, 2002 A method for estimating the extent of denitrification of Arctic polar vortex air is proposed. Previous estimates of denitrification using tracer-tracer scatter plots have not allowed for mixing-induced changes in tracer-tracer relationships in a ...

Stoichiometries of remineralisation and denitrification in global biogeochemical ocean models [PDF]
, 2009 Since the seminal paper of Redfield (1934), constant stoichiometric elemental ratios linking biotic carbon and nutrient fluxes are often assumed in marine biogeochemistry, and especially in coupled biogeochemical circulation models, to couple the global ...
