Chemical characteristics of waters around Kavaratti Atoll (Laccadives)
Estuarine characteristics of the lower reaches of the River Periyar (Cochin backwater)
Lower reaches of river Periyar were studied to assess longitudinal extent of salt water intrusion into the system during different seasons and also its effect on the flushing of pollutants introduced by the industries. ...
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 ...
Boron in seawater of Wadge bank region in the Indian Ocean
In the upper 200 m in the Wadge Bank region B varies from 3.09 to 4.95 mg.kg/1. B/Cl ratio ranges from 0.159 to 0.256. Depthwise distribution of B shows its inverse relationship with dissolved oxygen, direct relationship ...
Auto-correlograms and auto-regressive models of trace metal distributions in Cochin backwaters
Auto-correlation technique has been applied to study fluctuations in concentration profiles of chemical species in Cochin Backwaters (Kerala, India). No stability in time can be detected for particulate Mn at all stations, ...
Nitrite maxima in the Northern Arabian Sea
There are 2 nitrite maxima in the Northern Arabian Sea, one at the thermocline depth and the other at depths between 300 and 500 m. The 2nd maximum is more prominent in the northeastern part of the Arabian Sea. The 1st ...
Carbohydrates in the waters of ponds of Ramanthuruthu Island, Cochin
Particulate and dissolved carbohydrates in 4 ponds of the Ramanthuruthu Island (9 degrees 58.5'N lat. and 76 degrees 15.4'E long.) were studied for 1 yr (1978-79). Particulate carbohydrate concentration varied from 0.2 to ...
Chemical oceanography of the Arabian Sea Part iv Laccadive sea
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 ...
Particulate iron, manganese, copper and zinc in waters of the Cochin backwater
An incidence of very high phosphate concentrations in the waters around Andaman Islands
(Current Science Association, 1968)
Abnormally high concentrations of inorganic phosphates were encountered in the samples collected from the vicinity of the Andamans, during the cruises of INS kistna in September 1963, as a part of IIOE. Samples for analysis ...
