Anaerobic nitrification–denitrification mediated by Mn-oxides in meso-tidal sediments: Implications for N2 and N2O production..
(Elsevier, 2015)Field measurements in the Arcachon Bay (southwest France) indicated anaerobic production of NOx via nitrification, which was coupled to the reduction of Mn-oxides. To prove the occurrence of this process, laboratory microcosm ... -
Budgetary and biogeochemical implications of N sub(2)O isotope signatures in the Arabian Sea
(Macmillan, 1998)Nitrous oxide (N sub(2)O) is an important greenhouse gas that also plays a role in the chemistry of stratospheric ozone depletion, but its atmospheric budget has yet to be well-quantified sup(1-5). However, multi-isotope ... -
Contribution of N<sub>2</sub>O emissions to the atmosphere from Indian monsoonal estuaries
(International Meteorological Institute, 2013)Estuaries are known to contribute a significant amount of nitrous oxide (N<sub>2</sub>O) to the atmosphere; however, the contribution from the Indian estuaries is unknown. We made an attempt to estimate emissions of ... -
Nitrate reducing activity pervades surface waters during upwelling.
(Elsevier, 2014)Nitrate reducing activity (NRA) is known to be mediated by microaerophilic to anaerobic bacteria and generally occurs in the sub-surface waters. However, we hypothesize that NRA could become prominent in the surface waters ... -
Nitrification in Kochi backwaters
(Elsevier, 2008)Nitrification rates, as oxidation of sup(15) N-labelled ammonium and loss of nitrite from N-Serve treated samples, were measured in Kochi backwaters during three seasons. Nitrification rates ranged from undetectable to 166 ... -
Nitrogen and oxygen isotopic composition of N sub(2)O from suboxic waters of the eastern tropical North Pacific and the Arabian Sea - measurement by continuous-flow isotope-ratio monitoring
(Elsevier, 1997)Nitrous oxide (N sub(2)O) is a trace gas that is increasing in the atmosphere. It contributes to the greenhouse effect and influence the global ozone distribution. Recent reports suggest that regions such as the Arabian ... -
Seasonal and spatial variability in N sub(2)O distribution in the Arabian Sea
(Pergamon, 1999)Extensive measurements of nitrous oxide (N sub(2)O) were made in the central and eastern Arabian Sea during the northeast monsoon (February-March), intermonsoon (April-May) and southwest monsoon (July-August) seasons. The ...
