    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 ...

    The oceanic fixed nitrogen and nitrous oxide budgets: Moving targets as we enter the anthropocene? 

    Codispoti, L.A.; Brandes, J.A.; Christensen, J.P.; Devol, A.H.; Naqvi, S.W.A.; Paerl, H.W.; Yoshinari, T. (Institut de Ciencies del Mar de Barcelona, 2001)
    New data forced to raise previous estimates of oceanic denitrification. The revised estimate of approx. 450 Tg N yr sup(-1) (Tg = 10 sup(12) g) produces an oceanic fixed N budget with a large deficit (approx. 200 Tg N yr ...

    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 ...

    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, ...

    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 ...
