Denitrification processes in the Arabian Sea
(Indian Academy of Sciences, Bangalore, 1994)
Recent information on some consequences of the acute mid-water oxygen deficiency in the Arabian Sea, especially on carbon-nitrogen cycling, is reviewed. An evaluation of published estimates of water column denitrification ...
Seasonal variability of the vertical fluxes of @iGlobigerina bulloides@@ (D'Orbigny) in the northern Indian Ocean
(University of Hamburg, 1996)
Settling particles intercepted using time-series sediment traps at seven locations in the northern Indian Ocean have been examined for the spatial and temporal variability in the distribution and fluxes of @iGlobigerina ...
Effect of temperature and salinity on stable isotopic composition of shallow water benthic foraminifera: A laboratory culture study
(Bengaluru: Geological Society of India, 2013)
Quantitative estimation of past climatic parameters from stable isotopic composition of foraminifera relies on estimating the precise relationship between stable isotopic composition of the species analyzed and the ...
Chemical oceanography of the Arabian Sea: Part II - Equilibrium of inorganic nitrogen system
The concept pE, expressed as a dimensionless quantity to study the redox potential of a system at equilibrium, is applied to study the chemistry of the system NO-<sub>3</sub>-NO-<sub>2</sub>NH+<sub>4</sub> in the northern ...
Chemistry and hydrography of the Andaman Sea
The significance of oxygen as oxides and hydroxides in controlling the abundance and residence times of elements in seawater
A model is presented which signifies the role of oxygen (as oxides and hydroxides) in controlling the composition of seawater. respective concentration and residence times for the unknown elements can be estimated. Geometric ...
Arsenic content in the coastal and estuarine waters around Goa
(Indian Association for Limnology and Oceanography, 1974)
Marine nitrogen cycling- Some recent observations in the northwestern Indian Ocean
(Trivandrum: University of Kerala, 1987)
Published estimates of the rate of denitrification in the Arabian Sea have been evaluated and some new data on the nitrogen cycle have been presented Secondary nitrite maxima and nitrate reduction appear to be associated ...
Atypical behaviour of dissolved silicate in the Cochin backwater and Periyar river
Dissolved silicate was determined for 1 y (1982-83) covering a wide range of salinity from the estuarine mouth to the fresh water region. Silicate concentration ranged between 0.03 and 4.75 mgl/1. Silicate-salinity ...
Distribution of phosphates and silicates in the central western north Indian Ocean, in relation to some hydrographical factors
(National Institute of Sciences of India, 1968)
