Atypical ferromanganese micronodules from middle fan-valley system, Bay of Bengal
(Current Science Association, 1994)Ferromanganese micronodules having botryoidal and spheroidal morphogroups have been observed over a 0.22 million km@u2@@ area from the middle fan region of the Bay of Bengal. The bulk micronodules have 26.26% Mn, 1.02% Fe, ... -
Behaviour of Boron, Calcium and Magnesium in Mindola River Estuary (Gujarat)
(CSIR-NISCAIR, 1981)Ratios of B:Cl, Ca:Cl and Mg:Cl were generally within limit of river water at one end and seawater at the other. Percentage addition or removal (PA & PR) of B, Ca and Mg was calculated using the concept of the theoretical ... -
Behaviour of boron, calcium and magnesium in Purna and Auranga estuaries (Gujarat), west coast of India
(CSIR-NISCAIR, 1987)Ratios of B:Cl, Ca:Cl and Mg:Cl were generally within limit of river water at one end and seawater at the other. Percentage addition or removal (PA & PR) of B, Ca and Mg was calculated using the concept of the theoretical ... -
Boron, calcium and magnesium in Kavaratti lagoon water, Lakshadweep Archipelago
(NISCAIR, CSIR, 1997)Analysis of major elements in the water of Kavaratti lagoon show variations in the concentrations of boron from 4.08 to 4.25 mg kg sup(-1) (av. 4.15 mg kg sup(-1)); calcium from 420.4 to 429.3 mg kg sup(-1) (av. 424.79 mg ... -
Chemistry and behaviour of B, Ca and Mg in interstitial waters of sediments from the coastal and estuarine regions of Mandovi river along the west coast of India
(CSIR-NISCAIR, 1985)Interstitial waters of coastal and estuarine sediments show enrichment of B and Ca and a decrease in Mg. Increase in interstitial B in sediments is due to the downward diffusion from overlying water and release from solid ... -
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 ... -
Seasonal variations in Na, K, Mg and Ca charge balance in marine brown algae from Saurashtra Coast (NW coast of India)
(NISCAIR, CSIR, 1996)Seasonal variation of Na, K, Mg and Ca were estimated in Cystoseira indica, Sargassum tenerrimum and S. johnstonii. Abundance of these elements were higher during the rapid growth stage but decreased subsequently. Monovalent ... -
Seawater intrusion and behaviour of dissolved boron, fluoride, calcium, magnesium and nutrients in Vashisti Estuary
(Society of Biosciences, Muzaffarnagar, India, 1995)Behaviour of dissolved B, F, Ca, Mg and nutrients in partially stratified estuary of Vashiti River, Karnataka, India has been studied under stable conditions of riverine flow. The dominance of Mg over Ca concentration in ... -
Studies on calcium, magnesium and sulphate in the Mandovi and Zuari river system (Goa)
(CSIR-NISCAIR, 1981)Distribution of calcium, magnesium and sulphate have been examined in the tide-dominated Mandovi and Zuari river systems. Calcium and magnesium appear to take some part in the bio-geochemical cycles of the rivers and behave ...
