Morphometric analyses of the river basins in Goa
(Geographical Society of India, 1987)Morphometric analyses of seven river basins in Goa, India have been carried out. The linear and areal aspects of these basins are reported here. The plots of stream order versus stream numbers and stream orders versus mean ... -
Oxycephalus longipes Spandl, 1927 a valid species of the genus Oxycephalus (Amphipoda, Hyperiidea, Oxycephalidae)
(BRILL, 1988)This is the first description on an adult of @iOxycephalus longipes@@ Spandl, 1927. The original record was based on juvenile females. Since its description, the species has not been recorded again, hence its validity ... -
Upper ocean heat budget of western-north Pacific using satellite and ship observations
(Advanced Marine Science and Technology Society, 1997)Surface layer (0-17~'C isotherm depth) heat balance of a closed rectangular system (the Kuroshio system) in the North-West Pacific has been examined for a period of 10 days (from 16th to 25th, October, 1991), by considering ... -
Distribution of living planktonic foraminifera in the coastal upwelling region of Kenya, Africa
(CSIR-NISCAIR, 1988)Seventeen planktonic foraminiferal species have been encountered in the plankton samples collected off the Kenya coast; the most abundant species are Globigerinella aequilateralis, Globigerinoides ruber, G. sacculifer, ... -
Reference depth for geostrophic computation - A new method
(CSIR-NISCAIR, 1988)Various methods are available for the determination of reference depth for geostrophic computation. A new method based on the vertical profiles of mean and variance of the differences of mean specific volume anomaly (delta ... -
Maersk navigator oil spill in the great channel (Andaman Sea) in January 1993 and its environmental impact
(Elsevier, 1995)Observations on oil slicks, tar residues and dissolved petroleum hydrocarbons (DPH) shortly after the oil spill resulting from the tanker accident in January 1993 showed negligible impact on the Indian EEZ of the Great ... -
Acute toxicity and effect of some petroleum hydrocarbon on the metabolic index in Etroplus suratensis
(Muzaffarnagar: Society of Biosciences, 1997)Acute toxicity (LC@d50@@) and effect of some petroleum hydrocarbons (Toluene, Quinoline, Pyridine and Naphthalene) on the metabolic index (oxygen consumption rate) of an estuarine fish. @iEtroplus suratensis@@ is reported. ... -
Seasonal variability of the vertical fluxes of Globigerina bulloides (D'Orbigny) in the northern Indian Ocean
(University of Hamburg, 1996)Settling particles intercepted using time-series sediment traps at seven locations in the northern Indian Ocean have been examined for the spatial and temporal variability in the distribution and fluxes of @iGlobigerina ... -

Interspecific genetic divergence in sciaenids from Japan and its adjacent waters
(Ichthyological Society of Japan, 1988)Genetic divergence and phylogenetic relationships among @iNibea mitsukurii, N. albiflora, Pennahia argentata, Argyrosomus japonicus, Atrobucca nibe@@ and @iLarimichthys crocea@@ were investigated by examining the electrophoretic ... -
Planktonic foraminifera from a quaternary deep sea core from the southern Arabian Sea
(Geological Society of India, 1989)An investigation on planktonic foraminifera and calcium carbonate content of a box core collected at a depth of 2556 m from the southern part of the Arabian sea indicates faunal changes depicting Quaternary climatic ... -
Marine geophysical studies off Karwar, West Coast of India
(Geological Society of India, 1989)Geophysical studies of the southwestern continental margin revealed significant surface and subsurface topographic highs (ridges) trending NNW-SSE to NW-Se beyond the shelf break. Residual magnetic anomaly map depicts ... -
Distribution of phosphorus and phosphatisation along the western continental margin of India
(Geological Society of India, 1987)Phosphate content in the bulk sediments range from 0.02 to 2.17% and on carbonate free basis it varies from 0.03 to 6.5%. The partition studies indicate that contribution from the acid resistant detrital minerals (HCl ... -
Distribution, factor analysis and ecology of benthic foraminifera within inner shelf regime of Vengurla-Bhatkal sector, West Coast, India
(Geological Society of India, 1987)One hundred and two taxa of benthic foraminifera are reported from the neritic environment (15-60 m) of Vengurla - Bhatkal area. Q-mode factor analysis reveals 6 important foraminiferal assemblages accounting for 92% of ... -
Offshore extension of the structural element of Udipi, confirmation from marine magneties
(Geological Society of India, 1987)The isomagnetic anomaly map (1:3,00,000) reflects conspicuous E-W, NW-SE, WNW-ESE, NE-SW and N-S trends which are similar to that of the onshore Dharwar trend. The map also shows short wavelength, high amplitude anomalies ... -
Marine magnetic profiles from the Direction Bank to the Kori Bank, Western Continental shelf of India
(Geological Society of India, 1986)Total magnetic field intensity measurements along two parallel NW-SE tracks from the Direction Bank to the Kori Bank show corelatable magnetic anomalies. High frequency positive anomalies observed northwest of Kathiawar ... -
Mineralogy and chemistry of manganese nodules from the Southern part of Carlsberg Ridge
(Geological Society of India, 1985)Petrographic study indicates that the nucleus of nodules is generally composed of clay, volcanic glass, basalt fragments, and earlier nodules. polished sections indicate typical collomorphic globular segregations and partly ... -
Clay mineral distribution on the Kerala continental shelf and slope
(Geological Society of India, 1983)Seventy-five sediment samples collected from the Kerala continental shelf and slope during the 17th and 71st Cruises of @iRV gaveshani@@ were analysed by X-ray diffraction for clay mineral cntent. The distribution of total ... -
