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 ...
Benthic Studies in Goa Estuaries. Part 3. Annual Cycle of Macrofaunal Distribution, Production and Trophic Relations
(CSIR-NISCAIR, 1980)
Macrobenthos in Mandovi, Cumbarjua canal and Zuari estuaries, a physically interconnected tropical estuarine system which undergoes large seasonal changes in salinity distribution due to heavy monsoonal precipitation, is ...
Beach Morphological Variations over Micro-Time Scales
(CSIR-NISCAIR, 1980)
Nature and magnitude of beach changes over short periods have been studied at Calangute and Miramar in relation to tide, ground water level and relevant oceanographic and meteorological factors. Alternating zones of accretion ...
Seasonal Variations in Secondary Production of the Mandovi-Zuari Estuarine System of Goa
(CSIR-NISCAIR, 1980)
Mean rates of secondary production in the Mandovi, Zuari and Cumbarjua canal, Goa, India were 16.9, 35.9 and 32.4 mg C/m2/day respectively. The general hydrographic conditions of the Zuari were responsible for the higher ...
