Nitrogen isotopic studies in the suboxic Arabian Sea
(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, ...
Diversity of nitrite reductase genes (nirS) in the denitrifying water column of the coastal Arabian Sea
Denitrification often occurs in the water column, underlying zones of intense productivity and decomposition in upwelling regions. In the denitrifying zone off the southwest coast of India, high concentrations of nitrite ...
Isotopic composition of nitrate in the central Arabian Sea and eastern tropical North Pacific: A tracer for mixing and nitrogen cycles
(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 ...
Denitrifying bacterial community composition changes associated with stages of denitrification in oxygen minimum zones
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 ...
Seasonal oxygen deficiency over the western continental shelf of India
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 ...
