    Nitrogen transformations as inferred from the activities of key enzymes in the Arabian Sea oxygen minimum zone 

    Shailaja, M.S.; Narvekar, P.V.; Alagarsamy, R.; Naqvi, S.W.A. (Elsevier, 2006)
    Vertical distributions of the potential activities of some key enzymes mediating nitrification and denitrification were investigated within the oxygen (O2) minimum zone of the Arabian Sea at a number of locations between ...

    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 ...

    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 ...

    The Arabian Sea 

    Naqvi, S.W.A.; Naik, H.; Narvekar, P.V. (Blackwell, 2003)
    The Arabian Sea makes contributions to global biogeochemical cycles that are far in excess of what might be expected from its modest size. It experiences extremes in atmospheric forcing, asymmetrically distributed over the ...

    Carbon and nitrogen fluxes in the North Indian Ocean 

    Naqvi, S.W.A.; Naik, H.; DeSouza, W.; Narvekar, P.V.; Paropkari, A.L.; Bange, H.W. (Springer-Verlag, 2010)
    The land mass that blocks the Indian Ocean in the north at low latitudes profoundly influences the climate, circulation and biogeochemical processes of its northern basins. The asymmetrical distribution of freshwater and ...

    Phytoplankton associated with seasonal oxygen depletion in waters of the western continental shelf of India 

    Gauns, M.; Mochemadkar, S.; Pratihary, A.K.; Shirodkar, G.; Narvekar, P.V.; Naqvi, S.W.A. (2020)
    We report here results of a time series study carried out to understand seasonal variability of phytoplankton in relation to changes in dissolved oxygen based on observations at the Candolim Time Series (CaTS) station ...

    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) ...

    Increased marine production of N sub(2)O due to intensifying anoxia on the Indian continental shelf 

    Naqvi, S.W.A.; Jayakumar, D.A.; Narvekar, P.V.; Naik, H.; Sarma, V.V.S.S.; DeSouza, W.; Joseph, S.; George, M.D. (Macmillan, 2000)
    Eutrophication of surface waters and hypoxia in bottom waters has been increasing in many coastal areas, leading to very large depletions of marine life in the affected regions. These areas of high surface productivity and ...
