Magnetic lineations in the Central Indian Basin for the period A24-A21: a study in relation to the Indian Ocean Triple junction trace
(Elsevier, 1989)A detailed study of magnetics and bathymetry was carried out in the Central Indian Basin between latitudes 9 degrees S and 16 degrees 30'E and longitudes 73 degrees E and 79 degrees 30'E. The observed east-west trending ... -
Particulate carbohydrates in the Bay of Bengal
(CSIR-NISCAIR, 1989)Particulate matter collected from 77 water samples over a 3000 m water column was analyzed for particulate carbohydrates (PCHO). PCHO in the surface waters ranged from 43 to 143 mu g.l-1, and below 250 m it was 16.PCHO ... -
Particulate organic matter in shelf waters of Prinsesse Asrid Kyst, Antarctica
(Cambridge University Press, 1989)In the coastal and estuarine waters of Goa, particulate organic carbon (POC) varied from 0.52 to 2.51 mg l-1 and from 0.28 to 5.24 mg l-1 and particulate phosphorus (PP) varied from 0.71 to 5.18 mu g l-1 and from 0.78 to ... -

Particulate carbohydrates in the Arabian Sea
(Elsevier, 1989)Particulate carbohydrate (PECHO) was measured for 183 samples collected from 8 depths at 23 stations. The (PCHO) concentrations varied from 22 to 125 mu g.l-1 (x bar = 52.42 plus or minus 19.56 mu g.l-1 at the surface and ... -
Variation in meroplankton along 78 degrees E Meridian
(Marine Biological Association of India, 1989)Variations along the meridian 78 degrees E between 8 degrees N and 25 degrees S, based on 43 zooplankton samples were studied. Fish larvae exhibited fluctuations in abundance (26 to 57 specimens/IOSN haul) in the three ... -
Sedimentation of particulate material in stratified and nonstratified water columns in the Bombay high area of the Arabian sea
(Inter-Research, 1989)Sedimentation of particulate material at 22, 42 and 62 m was recorded at a station in the Bombay High area of the Arabian Sea from September 1985 to March 1986. Diatom numbers and physical structure, especially thermal ... -
Growth rate and chemical composition of a manganese nodule from the EEZ of Seychelles
(Geological Society of India, 1989)mhe ferro-manganese nodule collected in EEZ of Seychelles yields a growth rate of 1.5 mm/10 6Y 230Th (ex)/ and 230Th (ex)/ 232Th activity ratio methods indicating very slow growth of ferro-manganese nodules. The Mn/Fe and ... -
Petrography of basalts from the Carlsberg ridge
(CSIR-NISCAIR, 1989)Petrographic characteristics of basalts collected from a segment of the Carlsberg Ridge (lat. 3 degrees 35'N to 3 degrees 41'N; long. 64 degrees 05'E to 64 degrees 09'E) show typical pillow lava zonations with variable ... -

Marine magnetic anomalies over the Direction bank, off Bombay western continental shelf of India
(Association of Exploration Geophysicists, 1988)Total magnetic intensity data were collected over the Direction Bank, off Bombay on the western continental shelf of India and the isomagnetic anomaly map prepared at a contour interval of 25nT show NNW-SSE trend resemble ... -
Morphological and interlayer geochemical studies on manganese nodules from the southwestern Carlsberg ridge
(Elsevier, 1988)Mixed facies of manganese nodules from the southwestern Carlberg Ridge have been analysed for Mn, Fe, Ni, Cu, Co and Zn. Seventy one analyses including the averages presented for outer layer, inner layer and near-core ... -
Nature of the observed oscillatory flows in shelf waters of the western continental shelf of India
(Tirunelveli: JCSONLINE, 1988)Time series data on currents obtained from three Aanderaa current meters moored at a station depth of 92 m in the waters of the western continental shelf of India during May 1984 indicated the presence of oscillatory flows. ... -
