Chemical and environmental studies in ice and waters in and along Antarctica
(Current Science Association, 1983)
During the First Indian Ocean Expedition to Antarctica in anstral summer of 1981-82, some chemical investigations were carried out on the ice and waters of the Antarctic continent and along NE-SW transect in the southwestern ...
Nutrients in some estuaries of Kerala
(Indian Association for Limnology and Oceanography, 1983)
Some environmental parameters and nutrients like inorganic phosphate, nitrate, nitrite and ammonia from four estuaries namely Kallai, Beypore, Korapuzha and Mahe along north Kerala Coast were studied for an year (1980-81). ...
Base-Line Water Quality of the River Narmada (Gujarat)
(CSIR-NISCAIR, 1981)
Suspended solids, H,chlorides, DO, BOD, PO3-d4 -P, NO3- -N and NH+d4 -N were estimated at 12 stations along a 70 km stretch from the mouth of the river Narmada during March, May, June and August 1979. Tidal range of over ...
Calcium Phosphate Saturation in the Western Bay of Bengal
(CSIR-NISCAIR, 1980)
Temperature, inorganic phosphate concentration and pH seem to be the major factors influencing the degree of saturation of calcium phosphate in sea water. Two water regions can be demarcated in the study area based on the ...
Distribution of Urea in the Waters of the West Coast of India
(CSIR-NISCAIR, 1980)
Urea concentrations at the surface are high both in coastal and offshore waters in the region north of 15 degrees N (0.3-7.76 mu g at N/litre) and low in the region south of this latitude (0-1.5 mu g at N/litre). Vertical ...
Chemical oceanography of the Arabian Sea Part iv Laccadive sea
(CSIR-NISCAIR, 1979)
Data collected during the 10th (October 1976) and 31st (March-April 1978) cruises of R V Gaveshani suggest that water movements, considered typical of island-arc regions, are responsible for high levels of productivity ...
Distribution of nutrients in the shelf waters of the Arabian sea along the west coast of India
(National Institute of Sciences of India, 1968)
The paper presents a descriptive account of the distribution of phosphates, silicates and nitrates in the shelf waters of Arabian Sea along the West Coast of India including a brief mention about the hydrographical features ...
Chemical oceanography of the Arabian Sea: Part III - Studies on nutrient fraction and stoichiometric relationship in the Northern and the Eastern Basins
(CSIR-NISCAIR, 1976)
Phosphorus and inorganic nitrogen compounds have been divided into 'reserved' andoxidative fractions based on their relationships with apparent oxygen utilization in the northern and the north-eastern basins of the Arabian ...
Nutrients of the Cochin backwater in relation to environmental characteristics
(Springer, 1969)
The nutrient distribution of the Cochin Backwater was studied at 6 stations throughout the year The depth profiles of phosphorus (inorganic and organic), nitrogen (nitrate and nitrite) and silicon, showed a marked seasonal ...
Chemical oceanography of the Arabian Sea: Part II - Equilibrium of inorganic nitrogen system
(CSIR-NISCAIR, 1975)
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 ...
