Oxygen minimum zone of the open Arabian Sea: variability of oxygen and nitrite from daily to decadal timescales.
(European Geosciences Union, 2014)
The oxygen minimum zone (OMZ) of the Arabian Sea is the thickest of the three oceanic OMZ. It is of global biogeochemical significance because of denitrification in the upper part leading to N<SUB>2</SUB> and N<SUB>2</SUB>O ...
Carbon cycling in the northern Arabian Sea during the northeast monsoon: Significance of salps
(Inter-Research, 2002)
Winter cooling and mixing brings nutrients (nitrate and phosphate) to the surface waters over large parts of the northern Arabian Sea, but the rates of primary production as well as carbon export from the euphotic zone are ...
Denitrifying bacterial community composition changes associated with stages of denitrification in oxygen minimum zones
(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 ...
The Arabian Sea as a high-nutrient, low-chlorophyll region during the late southwest monsoon
(European Geosciences Union, 2010)
Extensive observations were made during the late southwest monsoon of 2004 over the Indian and Omani shelves, and along a transect that extended from the southern coast of Oman to the central west coast of India, tracking ...
Seasonal oxygen deficiency over the western continental shelf of India
(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 ...
Denitrification rates and excess nitrogen gas concentrations in the Arabian Sea oxygen deficient zone
(Elsevier, 2006)
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 ...
Methane in coastal and offshore waters of the Arabian Sea
(Elsevier, 2001)
Measurements of methane (CH sub(4)) made during two surveys in the eastern and central Arabian Sea in April-May, 1996, and August-September, 1997, corresponding to late Spring Intermonsoon (SI) and Southwest Monsoon (SWM) ...
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 ...
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 ...
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 ...
