Review of inorganic nitrogen transformations and effect of global climate change on inorganic nitrogen cycling in ocean ecosystems

Inorganic N transformations (nitrification, anaerobic ammonium oxidation, denitrification, and dissimilatory nitrate reduction to ammonium) are regulated by various biogeochemical factors linked either by the supply of electron acceptors and donors or by competition for electron acceptors. This review considers both the microbial community related to each process and the technical methods used to measure each process rate. With this background knowledge, this article summarizes how global climate change through increased pCO2, ocean acidification, deoxygenation and anthropogenic N deposition will alter oceanic N cycling, and finally emphasizes the need for comprehensive research on inorganic N transformation in marine ecosystems.
