Benthos of Cochin backwaters receiving industrial effluents
(CSIR-NISCAIR, 1989)Faunal composition of benthos and its spatial and temporal distribution at 9 stations in the northern limb of the Cochin backwaters are studied. An industrial belt is located about 18 km upstream of barmouth, and the ... -
Studies on shoreline stability at Mandovi estuary, Goa
(CSIR-NISCAIR, 1989) -
Wind stress, curl and vertical velocity in the Bay of Bengal during southwest monsoon, 1984
(CSIR-NISCAIR, 1989)Wind distribution observed during southwest monsoon of 1984 has used to derive the mean wind stress for the season at every 1 degree square grid and curl over the Bay of Bengal. Two regions of maximum wind stress are present ... -
Fluxes of inorganic and organic particulate matter in the Arabian Sea off Bombay

Size, surface texture, chemical composition and mineralogy interrelations in ferromanganese nodules of central Indian Ocean
(CSIR-NISCAIR, 1989)Fiftyseven ferromanganese nodules, classified into 3 size class (4,4-6 and 6-8 cm diam.), from the siliceous sediments of central Indian Ocean were analysed for transition metals and representative sample from each size ... -
Wave refraction and longshore current patterns along Calangute beach (Goa), west coast of India
(CSIR-NISCAIR, 1989)Wave refractions study for most predominant waves with 6,8,10 and 12 sec period and approaching from directions WNW, W and WSW has been carried out along the Calangute beach. The energy distribution and probable ... -
Distribution and behaviour of fluoride in Mandovi and Zuari estuaries, central west coast of India
(CSIR-NISCAIR, 1988)Fluoride concentrations in Mandovi and Zuari estuaries are regulated largely by salt water intrusion. Highest concentrations are observed during the premonsoon season, when the salt water intrusion is also the highest, the ... -
Distribution of particulate carbohydrate in the eastern Arabian sea along 15 (degrees) N
(CSIR-NISCAIR, 1988)The concentration of particulate carbohydrate varied from 38-158 mu g.l-1 and 19-239 mu g.l-1 in shelf and slope waters respectively. At 10 m water column the concentration of particulate carbohydrate increased with the ... -
Ferro-manganese oxide growth on shark teeth from cenral Indian Ocean basin
(CSIR-NISCAIR, 1988)Study of ferro-manganese oxide growth on apatitic substrates like shark teeth enamel from siliceous sediment environment (lat. 10 degrees S and long. 75 degrees E) suggests the changes in depositional environments within ... -
Effect of phase coupling on surface amplitude distribution of wind waves
(CSIR-NISCAIR, 1988)Nonlinear features of wind generated surface waves are considered here to be caused by nonrandomness (non-Uniform) in the phase spectrum. Nonrandomness in recorded waves, if present, would be generally obscured within the ... -
Nursery life of the marine prawn, Metapenaeus dobsoni (Miers) in the Mandovi estuary, along Goa Coast, India
(CSIR-NISCAIR, 1988)The nursery phase of Metapenaeus dobsoni was sequentially traced in the Mandovi Estuary of Goa (west coast of India). Peak postlarval ingression occurred between November and March. Of the total, 83.5% was distributed at ... -
Influence of estuaries on shelf foraminiferal species
(CSIR-NISCAIR, 1988)Dabhol-bhatkal stretch of the west coast of India is marked by a number of estuaries. Cavarotalia annectens is selected to monitor the influence of these estuaries on the inner shelf foraminiferal fauna. The percentage ... -
Variability in wave refraction and resultant nearshore current patterns: Exposed versus sheltered beaches along north Karnataka, west coast of India
(CSIR-NISCAIR, 1988)For predominant waves approaching from directions varying between SW and WNW and periods varying from 6 to 11 sec, the refraction function (Kd) shows amplification of wave heights resulting in concentration of wave energy ... -
Food conversion by Penaeus monodon (Fabricius) fed on decapsulated cysts of Artemia
(CSIR-NISCAIR, 1988) -
Unusual congregation of salps off Veraval and Bombay, west coast of India
(CSIR-NISCAIR, 1988)During September to October swarming of salps occur along the coasts off Veraval and Bombay. These congregations off Veraval are contributed by the single species Pegea confoederata recording an unusual biomass as high as ... -
Apparent relationship between thermal regime in Antarctic waters and Indian summer monsoon
(CSIR-NISCAIR, 1988)Austral winter seasonal and intra-seasonal variabilities of Sub-Tropical Convergence and Antarctic Polar Front are examined using sea surface temperature patterns published in GOSSTCOMP (Global Operational Sea Surface ... -
Zooplankton studies in Visakhapatnam harbour and nearshore waters, east coast of India
(CSIR-NISCAIR, 1988)Distribution of zooplankton biomass in the waters studied showed remarkable variations. The faunal composition was very diverse and the number of species present was more especially during late pre- and post-monsoon seasons ... -
Nutritional evaluation of Artemia Nauplii for the culture of marine crustacean Mysidopsis bahia (M.)
(CSIR-NISCAIR, 1988)A standard bioassay was carried out for the nutritional evaluation of Artemia nauplii of Indian and Sri Lankan strains using newly released juveniles of Mysidopsis bahia. After 12 d, results on survival (91-97%), length ...
