Denitrification rates and excess nitrogen gas concentrations in the Arabian Sea oxygen deficient zone
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 ...
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 ...
Benthic fluxes in a tropical estuary and their role in the ecosystem
In-situ measurements of benthic fluxes of oxygen and nutrients were made in the subtidal region of the Mandovi estuary during premonsoon and monsoon seasons to understand the role of sediment-water exchange processes in ...
Seasonal anoxia over the western Indian continental shelf
(American Geophysical Union, 2009)
The eastern Arabian Sea contains the only eastern-boundary-type upwelling environment in the entire Indian Ocean, albeit on a seasonal basis. During the southwest monsoon, when the surface current flows equatorward, upwelling ...
Impact of tropical cyclone on biogeochemistry of the central Arabian Sea
(American Geophysical Union, 2008)
Remotely sensed data are combined with shipboard measurements to investigate biogeochemical changes caused by a moderate tropical cyclone in the central Arabian Sea in December 1998. The sea surface temperature decreased ...
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 ...
Enhancement of oceanic nitrous oxide emissions by storms
Increased marine production of N sub(2)O due to intensifying anoxia on the Indian continental shelf
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 ...
The Arabian Sea
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 ...
