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 ...
Nitrogen cycling in the suboxic waters of the Arabian Sea
(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 ...
Marine nitrogen cycle
(National Council for Science and the Environment, 2006)
A microdiversity study of anammox bacteria reveals a novel Candidatus Scalindua phylotype in marine oxygen minimum zones
(Society for Applied Microbiology, 2008)
The anaerobic oxidation of ammonium (anammox) contributes significantly to the global loss of fixed nitrogen and is carried out by a deep branching monophyletic group of bacteria within the phylum Planctomycetes. Various ...
Organic carbon, and not copper, controls denitrification in oxygen minimum zones of the ocean
(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 ...
Introduction to Indian Ocean biogeochemical processes and ecological variability: Current understanding and emerging perspectives
(American Geophysical Union, 2009)
Despite a history of exploration dating back to the classical era and its leading role as a pathway for trade and cultural exchange for the great civilizations of those times, the Indian Ocean has consistently been subject ...
AoA Region: South Asian Seas
(UNESCO/IOC, 2009)
The South Asian Seas region lies in the northern extreme of the Indian Ocean. It includes the Arabian Sea and Bay of Bengal Large Marine Ecosystems (LME) along with their marginal basins as well as the Laccadive Sea and ...
Reduced iron associated with secondary nitrite maxima in the Arabian Sea
(Elsevier, 2007)
Dissolved iron and Fe(II) were measured in the oxygen minimum zone (OMZ) of the Arabian Sea in September 2004. The OMZ is a well-demarcated feature characterized by high rates of denitrification, and a deep nitrite maximum ...
The Indian Ocean
(Elsevier, 2008)
There are two unique aspects of geography of the Indian Ocean that profoundly influence its climate and circulation: (a) The Indian Ocean’s northern expanse is curtailed by the Eurasian landmass around the Tropic of Cancer ...
Data assimilation techniques in modeling ocean processes
(National Institute of Oceanography, India, 2001)
Three main classes of procedures in data analysis and assimilation viz. Objective Analysis, Optimal Interpolation and variational method, used to process the observed data on atmospheric and ocean parameters are briefly ...
