Effects of industrial waste disposal on the water quality of the river Kolak
(Indian Association for Limnology and Oceanography, 1980)
About 6 mld of industrial waste water is discharged without proper treatment in the fresh water zone of the river Kolak. Parameters like suspended solids, pH, chloride, DO, BOD, phosphate, nitrate, boron, sulphate and trace ...
Small Scale features of sound Velocity structure in the Northern Arabian Sea during February - May 1974
(CSIR-NISCAIR, 1980)
Microstructure of sound velocity in the upper 500 m of the northern Arabian Sea based on STD (salinity-temperature-depth profiler) data is presented. Relatively warm and saline waters of the Persian Gulf intruding into the ...
Annual Variations in Zooplankton from a Polluted Coastal Environment
(Indian Association for Limnology and Oceanography, 1980)
Seasonal changes in the composition and distribution of zooplankton from the coastal waters of Trivandrum were studied. The study indicated that the effluent discharged from a nearby titanium dioxide factory did not affect ...
Seasonal Variation in Heavy Metal Concentration in Mangrove Foliage
(Indian Association for Limnology and Oceanography, 1980)
Seasonal variation in the concentration of some heavy metals in the leaves of seven species of mangrove vegetation from Goa, revealed that maximum concentration of iron and manganese occurs during the monsoon season without ...
Seasonal changes in Carrageenan and other Biochemical Constituents of Hypnea Musciformis
(CSIR-NISCAIR, 1980)
Carrageenan content was maximum in winter. Near inverse relationship was observed between the total carbohydrate and carrageenan. Protein levels were highest when the nitrogenous nutrients were high
Topographic Changes of the Beach at Valiathura, Kerala
(CSIR-NISCAIR, 1980)
Studies on the topography of the beach and the inshore reaches at Valiathura, near Trivandrum reveal that the beach is in a stable equilibrium and presents well defined cyclicity in accretion and erosion every year. During ...
Physical features of Nearshore Waters off Karwar
(CSIR-NISCAIR, 1980)
Very little change in the hydrographic properties with depth during October 1975 to October 1976 was observed except during August-October, when waters of low temperature ( 24 degrees C), high salinity ( 35.5 ppt) and low ...
Seasonal Variations in Biochemical Composition of some Seaweeds from Goa Coast
(CSIR-NISCAIR, 1980)
Carbohydrate content in Chaetomorpha media, Dictyota dumosa, Ulva fasciata, Padina tetrastromatica, Hypnea musciformis and Gracilaria corticata was almost similar. Caloric content (5218 cal/g dry wt), organic carbon (29.17%) ...
Heterotrophic Bacterial populations in tropical Sandy Beaches
(Indian Association for Limnology and Oceanography, 1980)
Distribution pattern of heterotrophic bacterial flora of three sandy beaches of the west coast of India was studied. The population in these beaches was microbiologically different. Population peaks of halotolerant and ...
Organic Carbon content of Tropical Zooplankton
(CSIR-NISCAIR, 1980)
In the Zuari and Mandovi estuaries variations in organic carbon of zooplankton are 26.4-38.8 and 24-39.9% of dry weight respectively. Maximum carbon content of estuarine zooplankton is observed in November. Organic carbon ...
