Increased marine production of N sub(2)O due to intensifying anoxia on the Indian continental shelf
(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 ...
Carbon dioxide and nitrous oxide in the North Indian Ocean
(Current Science Association, Bangalore, India, 1995)
The understanding of biogeochemical cycling of carbon dioxide and nitrous oxide in the oceans is essential for predicting the fate of anthropogenically emitted components. The North Indian Ocean, with its diverse regimes, ...
A study of the carbon dioxide system in the northern Indian Ocean during premonsoon
(Elsevier, 1994)
Extensive data sets on the carbon dioxide system in the northern Indian Ocean have been obtained during the premonsoon season. A marked increase (~50 ~kM) in the total carbon dioxide (TCO@d2@@) content is observedin deep ...
Nitrous oxide in the western Bay of Bengal
(Elsevier, 1994)
Extensive observations on nitrous oxide (N@d2@@O) in the atmosphere and waters of the western Bay of Bengal during March-April 1991 yield surface saturations and atmospheric fluxes ranging from 89.3 to 213.9% (mean 125.2%), ...
Coastal versus open-ocean denitrification in the Arabian Sea
(The European Geosciences Union, 2006)
The Arabian Sea contains one of the three major open-ocean denitrification zones in the world. In addition, pelagic denitrification also occurs over the inner and mid-shelf off the west coast of India. The major differences ...
Severe fish mortality associated with 'red tide' observed in the sea off Cochin
(Current Science Association, 1998)
Severe fish mortality associated with the "red tide" phenomenon caused by Noctiluca blooms was observed in the sea off Cochin, Kerala, India at depths less than 40 m. The dead fish, almost entirely comprised of the threadfin ...
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
(Inter-Research, 2004)
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 ...
Ocean biogeochemistry and atmospheric composition: Significance of the Arabian Sea
(Indian Academy of Sciences, 2000)
The Arabian Sea is an important site of biogeochemical ocean-atmosphere transfers, which play a crucial role in regulating the atmospheric chemical composition and the earth's climate. Widespread denitrification resulting ...
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 ...
