Adaptations in Phytoplankton to Changing Conditions in Tropical Estuaries
(Indian Association for Limnology and Oceanography, 1980)Experimental studies on phytoplankton organisms from Cochin backwaters (a tropical estuary) have shown that many algal forms are adapted to changing conditions of salinity, light and nutrients. Photosynthesis in 12 species ... -
Present Status of Marine Pollution in India

Paleogene Reworked Foraminifera in Recent Sediments off Daman, Western India
(1980)The first record of reworked foraminiferal species in the Recent sediments off the coast of Daman is reported. Among others, @iQuadrimorphina advena, Uvigerina minuta, Gyroidinoides soldani, Bulimina aguafrescanensis@@ and ... -
Holocene Climatic Inferences from the Sediments of the Western Indian Continental Shelf

Sandwaves of the Gulf of Khambhat
(CSIR-NISCAIR, 1980)In the Gulf of Khambhat (Gujarat, India) the best formed sandwaves are seen in the west close to the Eastern Sand Bank. With increasing clay content and clay cover of the sea bed, the sandwaves become poorly formed. In the ... -
Contribution of Phytoplankton Photosynthesis to a Mangrove Ecosystem
(Indian Association for Limnology and Oceanography, 1980)Primary production in a fringing mangrove ecosystem was measured using two techniques. The first estimated gross oxygen production and community metabolism based on the diel difference in dissolved oxygen concentrations. ... -
On the Occurrence of Bullia Tranquebarica (Roding) Nassaridae (Gastropoda) in Kavaratti atoll (Lakshadweep)
(Current Science Association, 1980)A live buccinid gastropod Bullia tranquebarica belonging to family Nassaridae was collected from Kavaratti atoll in Lakshadweep island of Indian Ocean. Interesting pattern of its distribution is described. This is the ... -

Decapod Larvae from the Nearshore Waters of Karwar
(Indian Association for Limnology and Oceanography, 1980)Abundance of decapod larvae at three stations in Binge Bay, Karwar has been reported based on surface collections taken during the period October 1975 to September 1976. The larvae were very common in the Bay and the ... -
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 ... -
Zooplankton and Trichodesmium Phenomenon

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 ... -
Plankton Composition in the Coastal Waters between Jaigarh and Rajapur along West Coast of India
(Indian Association for Limnology and Oceanography, 1980)Diatoms dominated the phytoplankton population in the Konkan coastal waters. Rhizosolenia spp., Ceratulinia sp., Ditylum spp., Navicula sp. and Thalassiothrix spp. were the dominant diatoms observed in this area. Blue-green ... -
Distribution of Fe, Mn, Ni, Co, Cu and Zn in Non-Lithogenous Fractions of Sediments of Gulf of Kutch
(CSIR-NISCAIR, 1980)Contributions made by non-lithogenous fractions of sediments constitute a significant portion of the concentrations of the elements associated with the total sediment samples. The minor differences found in their distribution ... -
Production and Associations of Zooplankton in Estuarine and Nearshore Waters of Goa
(CSIR-NISCAIR, 1980)Zooplankton production in the Zuari and Mandovi estuaries indicated 2 peaks-one in November and another in March/April. In the nearshore waters very high value of zooplankton biomass was observed in April associated with ... -
Currents and Siltation at Dharamtar Creek, Bombay
(Indian Association for Limnology and Oceanography, 1980)Hydrographic data collected in Dharamtar Creek during 1976-77 have been analysed. This showed that the waters in the Creek are well mixed and the salinity varied with the tide. The tidal currents are found to be generally ... -
Zooplankton from the Shelf Watrs off the West Coast of India
(Indian Association for Limnology and Oceanography, 1980)Zooplankton in the shelf waters of India from Dabhol to Tuticorin was studied during the 17th cruise of R.V. Gaveshani in March 1977. Biomass values were relatively high in the central zone between Mangalore and Alleppey. ... -
Distribution of Strontium in Sediments of the Minicoy Atoll, Lakshadweep
(CSIR-NISCAIR, 1980)Sr content in 67 sediment samples collected from the Minicoy reef and lagoon varies from 3960 to 7000 ppm (av. 5630 ppm). The concentration increases from the reef (c 4,000 ppm) in the north and west to the centre of the ... -
General Expression for Spectrum of Magnetic Anomaly due to long Tabular body and its Characteristics
(CSIR-NISCAIR, 1980)A general expression for spectrum of magnetic anomalies-vertical, horizontal and total intensity - due to a long tabular body is derived which is used to estimate the body parameters. The analysis is extended to a marine ...
