Abstract
    Fixed nitrogen availability limits primary production in over half of the world's oceans. Oceanic oxygen minimum zones (OMZs) are responsible for about 35% of oceanic dinitrogen gas (N2) production and up to half of that occurs in the Arabian Sea. It has recently been argued that anaerobic ammonia oxidation (anammox) alone is responsible for fixed nitrogen loss in the OMZs; however, here it is shown that denitrification rather than anammox dominates the N2 loss term in the Arabian Sea.
