Carbon-Controlled Nitrogen Cycling in a Marine "Macrocosm": An Ecosystem-Scale Model for Managing Cultural Eutrophication
Smith SV and Hollibaugh JT. 1989. Carbon-Controlled Nitrogen Cycling in a Marine "Macrocosm": An Ecosystem-Scale Model for Managing Cultural Eutrophication. Marine Ecology Progress Series. 52(2):103-109
Both data which the authors present for Tomales Bay (California, USA), and general geochemical reasoning provide evidence to suggest that nearshore marine environments tend to be net heterotrophic by a small margin, and that these systems oxidize on the order of 1% of their primary production by denitrification. The rate of denitrification can be interpreted to be a simple stoichiometric function of the margin of heterotrophy. Carbon oxidation by denitrification is trivial to the total C budget, but fixed N loss is sufficient to cause apparent N-limitation of primary production in these systems.
