Abstract

The nitrogen and oxygen cycles of the eastern tropical South Pacific (ETSP) are investigated with a box and a high-resolution 3D model. The reduced remineralization rate under anoxic conditions slower than that via aerobic respiration can prevent nitrate depletion in the oxygen minimum zone. The local response of ETSP to nitrogen deposition and benthic remineralization indicates a stabilizing feedback. In the high-resolution 3D model, oxygen supply from the southern subtropical ocean into ETSP mainly impacts the deep ocean.
