Nitrogen lost at sea
Nitrogen lost at sea
Fixed nitrogen availability is the factor limiting primary production in more than half of the world's oceans. Recent reports have shown that anammox (anaerobic ammonium oxidation), rather than conventional denitrification producing dinitrogen gas (N2), is responsible for all or most of the fixed nitrogen loss in oxygen limited regions of the ocean. Ward et al. demonstrate that denitrification, rather than anammox, dominates the fixed nitrogen loss in the Arabian Sea. In this region denitrifying bacteria are more abundant than anammox bacteria, even when anammox rates are significant. This work addresses a major uncertainty in our understanding of the global nitrogen cycle and the fixed nitrogen inventory, confirming that denitrification is a major process in the overall marine nitrogen cycle.
