    Activity of the respiratory electron transport system and respiration rates within the oxygen minimum layer of the Arabian Sea 

    Naqvi, S.W.A.; Shailaja, M.S. (Pergamon, 1993)
    Measurements of the activity of the respirtory electron transport system (ETS) at 15 stations in the Arabian Sea during the northeast monsoon (December 1988) yield high respiration rates that do not correlate with the ...

    Nitrogen cycling in the suboxic Arabian Sea: Implications for atmospheric chemistry and climate 

    Naqvi, S.W.A. (Indian National Science Academy, New Delhi (India), 1999)
    An acute oxygen deficiency at mid-depths in the Arabian SEa leads to large-scale microbial conversion (denitrification) of the oxidised combined nitrogen species to molecular nitrogen (N sub(2)) at an estimated rate of ...

    Carbon dioxide and nitrous oxide in the Arabian Sea 

    Naqvi, S.W.A.; Sengupta, R.; DileepKumar, M. (American Geophysical Union, 1993)
    This review concentrates on some aspects of biogeochemical cycling of carbon and nitrogen in the Arabian Sea with emphasis on the atmospheric fluxes of CO sub(2) and N sub(2)O. The Arabian Sea appears to serve as a net ...

    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 

    Yoshinari, T.; Altabet, M.A.; Naqvi, S.W.A.; Codispoti, L.; Jayakumar, D.A.; Kuhland, M.; Devol, A. (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 ...

    Denitrification processes in the Arabian Sea 

    Naqvi, S.W.A. (Indian Academy of Sciences, Bangalore, 1994)
    Recent information on some consequences of the acute mid-water oxygen deficiency in the Arabian Sea, especially on carbon-nitrogen cycling, is reviewed. An evaluation of published estimates of water column denitrification ...

    An intermediate nepheloid layer associated with high microbial metabolic rates and denitrification in the northwest Indian Ocean 

    Naqvi, S.W.A.; DileepKumar, M.; Narvekar, P.V.; DeSousa, S.N.; George, M.D.; DeSilva, C. (American Geophysical Union, 1993)
    Extensive optical, physical chemical, and biochemical measurements made simultaneously in the northwest Indian Ocean reveal the occurrence of an intermediate nepheloid layer (INL) invariably associated with the secondary ...

    Nitrogen isotopic studies in the suboxic Arabian Sea 

    Naqvi, S.W.A.; Yoshinari, T.; Brandes, J.A.; Devol, A.H.; Jayakumar, D.A.; Narvekar, P.V.; Altabet, M.A.; Codispoti, L.A. (Indian Academy of Sciences, Bangalore, India, 1998)
    Measurements of sup(15)N/ sup(14)N in dissolved molecular nitrogen (N sub(2)), nitrate (NO sub(3) sup(-)) and nitrous oxide (N sub(2)O) and sup(18)O/ sup(16)O in N sub(2)O [expressed as delta sup(15)N and delta sup(18)O, ...

    The oxygen minimum zone in the Arabian Sea during 1995 

    Morrison, J.M.; Codispoti, L.A.; Smith, S.L.; Wishner, K.; Flagg, C.; Gardner, W.D.; Gaurin, S.; Naqvi, S.W.A.; Manghnani, V.; Prosperie, L.; Gundersen, J.S. (Pergamon, 1999)
    This paper focuses on the characteristics of the oxygen minimum zone (OMZ) as observed in the Arabian Sea over the complete monsoon cycle of 1995. Dissolved oxygen, nitrite, nitrate and density values are used to delineate ...

    Isotopic composition of nitrate in the central Arabian Sea and eastern tropical North Pacific: A tracer for mixing and nitrogen cycles 

    Brandes, J.A.; Devol, A.H.; Yoshinari, T.; Jayakumar, D.A.; Naqvi, S.W.A. (American Society of Limnology and Oceanography, 1998)
    The delta sup(15)N composition of nitrate and N sub(2) gas was measured in the eastern tropical North Pacific (ETNP) and central Arabian Sea (AS) suboxic regions. The delta sup(15)N of nitrate increased from 6 ppt at 2,500 ...

    Hydrochemistry of the Bay of Bengal: Possible reasons for a different water-column cycling of carbon and nitrogen from the Arabian Sea 

    Rao, C.K.; Naqvi, S.W.A.; DileepKumar, M.; Varaprasad, S.J.D.; Jayakumar, D.A.; George, M.D.; Singbal, S.Y.S. (Elsevier, 1994)
    A study on biogeochemical cycling in the western Bay of Bengal was undertaken during two seasons (pre-southwest monsoon and northeast monsoon of 1991). Relationships of the conservative tracers NO and PO with potential ...
