CSIR - National Institute of Oceanography
(Indian National Science Academy, 2016)
This is an institutional report of CSIR-National Institute of Oceanography, India showcasing its growth over last 50 years in Oceanographic research with special focus on Indian Ocean areas. The major research areas include ...
Effects of natural and human-induced hypoxia on coastal benthos
(European Geosciences Union, 2009)
Coastal hypoxia (defined here as <1.42 ml L sup(-1); 62.5 mew M; 2 mg L sup(-1), approx. 30% oxygen saturation) develops seasonally in many estuaries, fjords, and along open coasts as a result of natural upwelling or from ...
Variability of subsurface denitrification and surface productivity in the coastal eastern Arabian Sea over the past seven centuries
(SAGE, 2008)
Temporal variations over the last approx. 700 years in surface productivity and subsurface denitrification in the coastal eastern Arabian Sea (off Goa, India), a hydrographically unique environment that experiences seasonal ...
Mineralogy and Sr–Nd isotopes of SPM and sediment from the Mandovi and Zuari estuaries: Influence of weathering and anthropogenic contribution
(Elsevier, 2015)
Clay minerals and Sr–Nd isotopes of suspended particulate matter (SPM) and bottom sediment were investigated along transect stations of the Mandovi and Zuari estuaries, western India to determine the provenance and role ...
The oceanic fixed nitrogen and nitrous oxide budgets: Moving targets as we enter the anthropocene?
(Institut de Ciencies del Mar de Barcelona, 2001)
New data forced to raise previous estimates of oceanic denitrification. The revised estimate of approx. 450 Tg N yr sup(-1) (Tg = 10 sup(12) g) produces an oceanic fixed N budget with a large deficit (approx. 200 Tg N yr ...
Variations in Denitrification and Ventilation Within the Arabian Sea Oxygen Minimum Zone During the Holocene
(John Wiley & Sons, 2018)
The continental slope of India is exposed to an intense perennial oxygen minimum zone (OMZ) supporting pelagic denitrification. Sediments that are presently in contact with the lower boundary of the denitrification zone ...
Is delta sup(15)N of sedimentary organic matter a good proxy for paleodenitrification in coastal waters of the eastern Arabian Sea?
(American Geophysical Union, 2009)
Recently published sedimentary records of delta sup(15)N from several coastal areas affected by both natural and anthropogenically produced shallow hypoxia with the objective of testing this as a proxy for denitrification ...
Ocean iron fertilization
(TERI Press, 2011)
In 2009 and 2010, an Indo-German scientific expedition dusted the ocean with iron to stimulate the biological pump that captures atmosphereic carbon dioxide. Two onboard scientists tell the story of this controversial ...
Impact of physical processes on oxygen loss and production of hydrogen sulphide and methane in a tropical freshwater reservoir
(Springer, 2021)
Carbon neutrality of tropical reservoirs is a big concern in recent years as some estimates project high methane emission from these reservoirs. While there are studies available on the impact of physical processes ...
Environmental association of heterotrophic micro-eukaryotes in the varying biogeochemical regimes of the Arabian Sea, resolved via high-throughput sequencing
(Springer, 2021)
The diverse physicochemical conditions prevailing in the Arabian Sea are expected to result in marked spatial variations in heterotrophic flagellate (HF) and ciliate communities. Here, we report the environmental association ...
