Denitrifying bacterial community composition changes associated with stages of denitrification in oxygen minimum zones

Jayakumar, D.A.; O'Mullan, G.D.; Naqvi, S.W.A.; Ward, B.B. (Springer, 2009)

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 ...

Nitrogen cycling in the suboxic waters of the Arabian Sea

Devol, A.H.; Naqvi, S.W.A.; Codispoti, L.A. (Springer, 2006)

Arabian Sea contains one of the world's three large oxygen deficient zones (ODZ). Within the ODZ oxygen concentration is vanishingly small between about 200 and 800 m depth and in this depth interval denitrifications is ...

Seasonal oxygen deficiency over the western continental shelf of India

Naqvi, S.W.A.; Naik, H.; Jayakumar, D.A.; Shailaja, M.S.; Narvekar, P.V. (Springer, 2006)

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 ...

Hydrochemistry of the Bay of Bengal: Possible reasons for a different water-column cycling of carbon and nitrogen from the Arabian Sea

Rao, C.K.; Naqvi, S.W.A.; DileepKumar, M.; Varaprasad, S.J.D.; Jayakumar, D.A.; George, M.D.; Singbal, S.Y.S. (Elsevier, 1994)

A study on biogeochemical cycling in the western Bay of Bengal was undertaken during two seasons (pre-southwest monsoon and northeast monsoon of 1991). Relationships of the conservative tracers NO and PO with potential ...
