Water Quality of the River Damanganga (Gujarat)
(CSIR-NISCAIR, 1980)Water quality (pH, suspended solids, chlorides, DO, BOD, reactive and total phosphorus, nitrates and boron) of River Damanganga which receives 0.2 mld of industrial waste into its fresh water zone through Pimparia River ... -
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 ... -
Some aspects on the variations in depositional flux of excess Thorium-230 in the central Indian basin during Late Quaternary
(Indian Academy of Sciences, Bangalore, 1994)Examined in this paper is the tentative history of the depositional flux of @u230@@Th@dxs@@ (the unsupported fraction of @u230@@Th scavenged from the overlying water column), for the Late Quaternary period from a sediment ... -
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 ... -
Occurrence of Genus Monostroma (Ulvales, Chlorophyta) from Ratnagiri (Maharashtra)
(Indian Association for Limnology and Oceanography, 1980)The occurrence of a genus Monostroma has been recorded from the Shirgaon creek at Ratnagiri along the central west coast of India. The Monostroma sp. was found in the brackish water environment with low salinity, high ... -
Biochemical Changes and Energy content of the Mangrove, Rhizophora Mucronata, Leaves during Decomposition
(CSIR-NISCAIR, 1980)Decomposition of Rhizophora mucronata leaves both in the laboratory and in the field resulted in the loss of organic carbon and ash and increase in total nitrogen, organic matter, protein and caloric content. In the ... -
Power Spectra of Currents off Bombay
(CSIR-NISCAIR, 1980)Current measurements were carried out using a recording current meter across the continental shelf off Bombay, Maharashtra, India at 4 stations from an anchored ship. Power spectra were computed for selected lengths of ... -
Fish Kill in Chitrapuzha

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 ... -
Conversion Efficiency in the Shrimp, Metapenaeus Monoceros (Fabricius), Fed on Decomposed Mangrove Leaves
(CSIR-NISCAIR, 1980)Feeding experiments were carried out with Metapenaeus monoceros using mangrove leaves at different stages of decomposition, in combination with rice bran. Maximum conversion efficiency was found in shrimps fed completely ... -
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 -
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%) ... -
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 ... -
Acoustic Masking due to Gases in Shallow Seismic profiling on the shelf off Bombay
(CSIR-NISCAIR, 1980)Shallow seismic profiling on the inner shelf off Bombay indicates 25-35 m thick acoustically transparent clays covering the seabed. At depth of 22 to 30 m and 50 m the profiles and echograms are marked by turbidity resembling ... -
