- Abstract:
- This research will look for direct evidence of the novel process of anaerobic ammonium oxidation at the oxic/anoxic interface in the Arabian Sea and assess its significance to the formation of oceanic nitrous oxide. The water column at several sites in the oxygen minimum zone of the Arabian Sea will be characterised by shipboard measurements and where potential zones are identified direct measurements of anaerobic ammonium oxidation will be executed using a suite of 15N tracer incubations. The potential depletion or enrichment of delta 15N and delta 180 in N2O via anaerobic ammonium oxidation and hence a rationalisation of the 'heavy' N2O found in this region will also be carried out. These objectives will be supplemented by a thorough characterisation of water column chemistry e.g. sub-micromolar NH4+ concentrations and dissolved and particulate organic matter concentrations.
