    Oxygen minimum zone of the open Arabian Sea: variability of oxygen and nitrite from daily to decadal timescales. 

    Banse, K.; Naqvi, S.W.A.; Narvekar, P.V.; Postel, J.R.; Jayakumar, D.A. (European Geosciences Union, 2014)
    The oxygen minimum zone (OMZ) of the Arabian Sea is the thickest of the three oceanic OMZ. It is of global biogeochemical significance because of denitrification in the upper part leading to N<SUB>2</SUB> and N<SUB>2</SUB>O ...

    Carbon cycling in the northern Arabian Sea during the northeast monsoon: Significance of salps 

    Naqvi, S.W.A.; Sarma, V.V.S.S.; Jayakumar, D.A. (Inter-Research, 2002)
    Winter cooling and mixing brings nutrients (nitrate and phosphate) to the surface waters over large parts of the northern Arabian Sea, but the rates of primary production as well as carbon export from the euphotic zone are ...

    Denitrifying bacterial community composition changes associated with stages of denitrification in oxygen minimum zones 

    Jayakumar, D.A.; O'Mullan, G.D.; Naqvi, S.W.A.; Ward, B.B. (Springer, 2009)
    Denitrification in the ocean is a major sink for fixed nitrogen in the global N budget, but the process is geographically restricted to a few oceanic regions, including three oceanic oxygen minimum zones (OMZ) and hemipelagic ...

    The Arabian Sea as a high-nutrient, low-chlorophyll region during the late southwest monsoon 

    Naqvi, S.W.A.; Moffett, J.W.; Gauns, M.; Narvekar, P.V.; Pratihary, A.K.; Naik, H.; Shenoy, D.M.; Jayakumar, D.A.; Goepfert, T.J.; Patra, P.K.; Al-Azri, A.; Ahmed, S.I. (European Geosciences Union, 2010)
    Extensive observations were made during the late southwest monsoon of 2004 over the Indian and Omani shelves, and along a transect that extended from the southern coast of Oman to the central west coast of India, tracking ...

    Seasonal oxygen deficiency over the western continental shelf of India 

    Naqvi, S.W.A.; Naik, H.; Jayakumar, D.A.; Shailaja, M.S.; Narvekar, P.V. (Springer, 2006)
    The North Indian Ocean contains about two-third of the global continental-margin area affected by natural oxygen deficiency (O2 less than 0.2 mL L sup(-1)) in the water column. Also, the littoral countries of this ...

    Budgetary and biogeochemical implications of N sub(2)O isotope signatures in the Arabian Sea 

    Naqvi, S.W.A.; Yoshinari, T.; Jayakumar, D.A.; Altabet, M.A.; Narvekar, P.V.; Devols, A.H.; Brandes, J.A.; Codispoti, L.A. (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 ...

    Denitrification rates and excess nitrogen gas concentrations in the Arabian Sea oxygen deficient zone 

    Devol, A.H.; Uhlenhopp, A.G.; Naqvi, S.W.A.; Brandes, J.A.; Jayakumar, D.A.; Naik, H.; Gaurin, S.; Codispoti, L.A.; Yoshinari, T. (Elsevier, 2006)
    Rates of canonical, i.e. heterotrophic, water-column denitrification were measured by sup(15)N incubation techniques at a number of coastal and open ocean stations in the Arabian Sea. Measurements of N2 :Ar gas ratios were ...

    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 ...

    A sink for atmospheric carbon dioxide in the northeast Indian Ocean 

    DileepKumar, M.; Naqvi, S.W.A.; George, M.D.; Jayakumar, D.A. (American Geophysical Union, 1996)
    Intensive observations in the northeast Indian Ocean (Bay of Bengal) during the pre-southwest and northeast monsoon seasons 1991 reveal that freshwater discharge from rivers of the Indian subcontinent exerts the dominant ...

    Methane in coastal and offshore waters of the Arabian Sea 

    Jayakumar, D.A.; Naqvi, S.W.A.; Narvekar, P.V.; George, M.D. (Elsevier, 2001)
    Measurements of methane (CH sub(4)) made during two surveys in the eastern and central Arabian Sea in April-May, 1996, and August-September, 1997, corresponding to late Spring Intermonsoon (SI) and Southwest Monsoon (SWM) ...
