Activity of the respiratory electron transport system and respiration rates within the oxygen minimum layer of the Arabian Sea

Naqvi, S.W.A.; Shailaja, M.S. (Pergamon, 1993)

Measurements of the activity of the respirtory electron transport system (ETS) at 15 stations in the Arabian Sea during the northeast monsoon (December 1988) yield high respiration rates that do not correlate with the ...

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 ...

Organic carbon, and not copper, controls denitrification in oxygen minimum zones of the ocean

Ward, B.B.; Tuit, C.B.; Jayakumar, A.; Rich, J.J.; Moffett, J.; Naqvi, S.W.A. (Elsevier, 2008)

Incubation experiments under trace metal clean conditions and ambient oxygen concentrations were used to investigate the response of microbial assemblages in oxygen minimum zones (OMZs) to additions of organic carbon and ...

The oxygen minimum zone in the Arabian Sea during 1995

Morrison, J.M.; Codispoti, L.A.; Smith, S.L.; Wishner, K.; Flagg, C.; Gardner, W.D.; Gaurin, S.; Naqvi, S.W.A.; Manghnani, V.; Prosperie, L.; Gundersen, J.S. (Pergamon, 1999)

This paper focuses on the characteristics of the oxygen minimum zone (OMZ) as observed in the Arabian Sea over the complete monsoon cycle of 1995. Dissolved oxygen, nitrite, nitrate and density values are used to delineate ...
