Studies on boron along the central west coast of India
(CSIR-NISCAIR, 1982)
Boron in its inorganic form in the Arabian Sea waters varies from 1.17 to 4.74 mg/kg. There is, at some stations, depthwise correlation between inorganic B and primary productivity. B/Cl varies from 0.122 to 0.238 for ...
On the distribution of fluoride, calcium and magnesium in the waters off the central west coast of India
(Indian Association for Limnology and Oceanography, 1982)
The distribution of fluoride, calcium and magnesium was studied in the waters off the central west coast of India. The averages F/Cl, Ca/Cl and Mg/Cl ratios observed are (6.83 plus or minus 0.023) x 10@u-5@@, (0.02194 plus ...
Fluoride, Bromide and Iodide in the Arabian Sea
(CSIR-NISCAIR, 1982)
Fluoride concentrations varying from 1.32 mg/l at the surface to 1.37 mg/l at depth showed an average of 1.35 + or - 0.004 mg/l with F/Cl of (6.65 + - 0.07) x 10/5. Average bromide was 70 mg/l with Br/Cl of 0.00347. Bromide ...
Tidal Mixing in Dahej Creek Waters
(Indian Association for Limnology and Oceanography, 1982)
Mixing characteristics of a tidal inlet near Dahej at the mouth of Narmada River, Gujarat, India are examined in terms of tides, currents and bathymetry. The dilution potential of the Dahej Creek waters during a tidal march ...
Determination of copper in natural waters and sediments by extraction spectroscopic method
(CSIR-NISCAIR, 1982)
A sensitive extraction spectrophotometric method has been developed based on the formation and extraction of Cu(II)-neocuproine-rosenbengal into chloroform. The molar extinction coefficient of the system is 55.500 and ...
Dissolved and particulate trace metals in the western Bay of Bengal
(CSIR-NISCAIR, 1982)
Concentrations of Cu, Zn, Mn, Fe, Co, Ni and Pb, both in soluble and particulate forms were studied in the upper 200 m depth. Correlation between the trace metal concentration and the primary productivity was also investigated. ...
Denitrification in the Arabian Sea
(Elsevier, 1982)
Estimates of the amount of denitrification in the Arabian Sea are inconsistent, and so two methods of calculations of 'original' nitrate concentrations used in earlier studies have been reviewed. Nitrite at intermediate ...
On the Distribution of Bromide and Bromide/Chlorinity ratios in the Waters of the Arabian sea off Central Indian Coast
(Indian Association for Limnology and Oceanography, 1981)
Water samples from surface to 2000 m depth at two stations in the Arabian Sea collected during the 82nd cruise of R V Gaveshani in November, 1980 were analysed for bromide. The average bromide concentration was 0.068 g/kg ...
Chemistry and Hydrography of the Andaman Sea
(CSIR-NISCAIR, 1981)
Particulate carbohydrate in the euphotic zone of the Bay of Bengal
(Indian Association for Limnology and Oceanography, 1981)
Particulate matter collected from the Bay of Bengal was analysed for carbohydrate and chlorophyll a. The distribution of chlorophyll a was different from that of carbohydrate. Chlorophyll a increased from north to south, ...
