A petrographic study of Precambrian quartzites from Goa coast
(Indian Association for Limnology and Oceanography, 1980)
A petrographic and heavy minerals study of quartzites along the Goa Coast, India has been undertaken to decipher their sediment history. The quartzite outcrops exhibit well preserved primary sedimentary structures like ...
Recent advances in oceanography and new perspectives in fisheries management
(Indian Association for Limnology and Oceanography, 1985)
The reason de etre for the swing back to an empirical approach in fisheries management as an interim measure towards developing a truly rational method is discussed. The importance of physical oceanographic and meteorological ...
Salt balance and mixing in the Bay of Bengal
(1986)
Basic fields of temperature salinity, density and currents in the Bay of Bengal are investigated using data archieved at the National Oceanographic Data Centre (NODC) Washington, D.C. and the Indian National Oceanographic ...
Swarming of Creseis acicula Rang (Pteropoda) in the coastal waters of Goa
(Indian Association for Limnology and Oceanography, 1983)
Swarms of Creseis acicula Rang (Pteropoda) were observed in the coastal waters of Goa regularly in October, from 1976 to 1980. The highest biomass value obtained for this species was 494 ml/100 m@u3@@, forming 96% of ...
Frequency distribution of foraminifera off Trivandrum, west coast of India
(CSIR-NISCAIR, 1985)
Fifty two species belonging to 31 genera of recent foraminifera have been identified from sediment samples collected from the inshore waters. Based on relative abundance of species, it is observed that along the coast, the ...
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. ...
Toxic effects of domestic sewage on zooplankton
(National Institute of Oceanography, Goa, 1987)
The toxic effects of raw domestic sewage on different groups of zooplank-ton, was tested in the laboratory for evaluating acute toxicity. 24 hr., LC-50 values for larvae of stomatopods, gastropods and chaetognaths (2-7% ...
Distribution of iodate in the south western Bay of Bengal
(CSIR-NISCAIR, 1983)
Low concentration of iodate at surface (Ca. 0.2 mu M) and an increase in deeper waters (Ca, 0.55 mu M) were observed in south western Bay of Bengal. A nutrient like behaviour of iodate was also found and phosphate showed ...
Effect of attenuation correction on surface amplitude distribution of wind waves
(National Institute of Oceanography, Goa, 1987)
Some selected wave profiles recorded using a ship borne wave recorder are analysed to study the effect of attenuation correction on the distribution of the surface amplitudes. A new spectral width parameter is defined to ...
