    Biogeochemistry of methane in a tropical monsoonal estuarine system along the west coast of India 

    Araujo, J.; Naqvi, S.W.A.; Naik, H.; Naik, R. (Elsevier, 2018)
    Estuaries are known to be important sources of methane (CH4) to the atmosphere. However, a lack of adequate field studies in understanding the sources/sinks of CH4 in estuaries hampers the global atmospheric budgeting. ...

    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 ...

    Sedimentary pigments and nature of organic matter within the oxygen minimum zone (OMZ) of the Eastern Arabian Sea (Indian margin) 

    Rasiq, K.T.; Kurian, S.; Karapurkar, S.G.; Naqvi, S.W.A. (Elsevier, 2016)
    Sedimentary pigments, carbon and nitrogen content and their stable isotopes were studied in three short cores collected from the oxygen minimum zone (OMZ) of the Eastern Arabian Sea (EAS). Nine pigments including chlorophyll ...

    Nitrogen fixation rates in the eastern Arabian Sea 

    Ahmed, A.; Gauns, M.; Kurian, S.; Bardhan, P.; Pratihary, A.K.; Naik, H.; Shenoy, D.M.; Naqvi, S.W.A. (Elsevier, 2017)
    The Arabian Sea experiences bloom of the diazotroph Trichodesmium during certain times of the year when optimal sea surface temperature and oligotrophic condition favour their growth. We measured nitrogen fixation rates ...
