Behaviour of boron, calcium and magnesium in Purna and Auranga estuaries (Gujarat), west coast of India
(CSIR-NISCAIR, 1987)Ratios of B:Cl, Ca:Cl and Mg:Cl were generally within limit of river water at one end and seawater at the other. Percentage addition or removal (PA & PR) of B, Ca and Mg was calculated using the concept of the theoretical ... -
Effect of industrial effluents on biota: a case study off Mangalore, west coast of India
(CSIR-NISCAIR, 1987)The inshore waters off Mangalore, receiving industrial effluent discharge were studied for phytoplankton, zooplankton and benthic populations, from December 1984 to May 1985. Total phytoplankton population varied from 7 ... -
Identification of oil pollution sources in harbour waters

Contribution of the thraustochytrid Corallochytrium limacisporum Raghu-kumar to microbial biomass in coral reef lagoons
(CSIR-NISCAIR, 1987)ATP and organic carbon (OC) contents of cells of 5 isolates of thraustochytrids, including one of Corallochytrium limacisporum were estimated from cultures OC:ATP ratio in these isolates averaged 99 Based on these and the ... -
Concentration and toxicity of some metals in zooplankton from nearshore waters of Bombay
(CSIR-NISCAIR, 1985)Zooplankton samples collected from 4 stations located in the nearshore waters of Bombay were analysed for Cu, Co, Mn, Ni and Cd. Concentrations of Co, Mn and Ni were more in copepods and gelatinous organisms than in mysids ... -
Urea as nitrogen source for phytoplankton production in coastal waters of Goa
(CSIR-NISCAIR, 1985)Annual variation of urea in coastal waters off Goa, India is 0 to 2.92 mu g-at N.1/1 and 0 to 4.69 mu g-at N.1/1 in adjacent estuarine waters of Mandovi. Peaks of phytoplankton production accompanied with the decrease in ... -
Relative toxicity of oil dispersants to Mytilus viridis and Macrobrachium idella
(CSIR-NISCAIR, 1984)There was a great variation in the relative toxicity of different oil dispersants. Dispersant IB 2/80 was most toxic and dispersant IB 11/80 was not lethal at the highest concentration tested. The ranking order of the ... -
Studies on growth and age of bivalves from temperate and tropical estuarine ecosystems
(CSIR-NISCAIR, 1984)Comparison of growth progression and age composition of Abra alba and Nuculana minuta from temperate estuarine ecosystem with Meretrix casta and Paphia malabarica from tropical estuarine environment, revealed that the ... -
Application of vertical advection-diffusion model for studying CO2 and O2 profiles in central Arabian Sea
(CSIR-NISCAIR, 1984)The vertical advection-diffusion model proposed by Craig has been applied to the study of CO sub(2) and O sub(2) profiles in Central Arabian Sea. Distributions of total CO Sub(2) and O sub(2) are explained better by ... -
Studies on carbon dioxide system in central Arabian sea
(CSIR-NISCAIR, 1984)Data on pH and total alkalinity have been utilised in the study of carbon dioxide and its species in Central Arabian Sea Total carbon dioxide and partial pressure of carbon dioxide remain fairly constant in the upper layers ... -
Boron in seawater of Wadge bank region in the Indian Ocean
(CSIR-NISCAIR, 1984)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 ... -
Study of longshore current equations for currents in Visakhapatnam beach
(CSIR-NISCAIR, 1984)Longshore currents were measured along the Visakhapatnam Beach, Andhra Pradesh, India at weekly intervals from March 1978 to March 1979. Visual observations on breaker characteristics were also made during this period. ... -
Effect of tide on the variability of zooplankton in the nearshore waters of Thal, Maharashtra
(CSIR-NISCAIR, 1983)Quantitative and qualitative difference in zooplankton in relation to the tide were studied along 3 transects located off Thal, Maharashtra, India during Feb. 1980 to Jan. 1981. Variation in zooplankton biomass for the ... -

Physico-chemical characteristics of the Mahanadi estuarine ecosystem, east coast of India
(CSIR-NISCAIR, 1988)Seasonal pattern of temperature, salinity, pH, dissolved oxygen, phosphate, nitrate and silicate profiles of the Mahanadi estuary have been studied. On the basis of physical characteristics, Mahanadi estuarine system can ... -
Growth and production of benthic bivalve, Gafrarium pectinatum (Linn.) from west coast of India
(CSIR-NISCAIR, 1986)Production of Gafrarium pectinatum was characterized by the presence of 0,1 and 2 y age groups Average monthly growth in length varied from 0.6 to 3mm The relationship between length and weight was isometric The average ... -
Circulation and watermass structure in the Central Arabian Sea during December 1982
(CSIR-NISCAIR, 1986)After the cessation of the SW monsoon over Arabian Sea, the North Equatorial Current sets strongly and the low saline waters from the Bay of Bengal and the equatorial Indian Ocean penetrate into the Arabian Sea. This results ... -
