Physical and elastic properties of marine sediments off Bombay, India
(Springer, 1986)
Keeping in view the paucity of information as to the nature of the marine sediments from the continental shelf adjoining the Indian subcontinent, a number of shallow seismic surveys were carried out, nearshore and offshore ...
Fluctuation in glacial and interglacial sediment discharge of the River Indus as seen in the core from the Arabian Sea
(CSIR-NISCAIR, 1985)
Sediment core from the upper continental slope off Saurashtra Coast has been analysed for CaCO sub(3) and coarse fraction contents in addition to planktonic foraminifera and clay mineralogy. Based on CaCO sub(3) and ...
Sediment depositional environment in some bays in Central west coast of India
(CSIR-NISCAIR, 1984)
Sediments in Kalbadevi and Mirya Bays are well sorted while those in Ratnagiri Bay are poorly sorted. Mean size of the sediments varies among the bays. Sediments in Kalbadevi Bay are both positively and negatively skewed ...
Geochemical evidence of terrigenous influence in deep-sea sediments upto 8°S in the Central Indian basin
(Elsevier, 1989)
Thirty-two representative deep-sea sediment samples have been studied from three manganese nodule-bearing environments in the Central Indian Basin: diatomaceous-radiolarian ooze-clay, pelagic brown clay and calcareous ooze. ...
Determination of petroleum hydrocarbons in sediment samples from Bombay harbour, Dharamtar creek and Amba river estuary
(Scientific Publishers, 1989)
The surface sediment samples were collected by van Veen grab sampler during premonsoon, monsoon and postmonsoon seasons from Bombay harbour, Dharamtar creek and Amba river estuary Moisture content of the samples ranges ...
Extractable organics in surface sediments from Thana creek and Bombay harbour
(CSIR-NISCAIR, 1989)
Considerable variations in hydrocarbon and fatty acid levels in surface sediments from Thana creek and Bombay harbour were observed Sediments from the westernside nearshore locations yielded higher values The residues were ...
Effect of sediment-water interface 'boundary layer' on exposure of nodules and their abundance: a study from seabed photos
(Geological Society of India, 1989)
The results obtained from seabed photos and boomerang grab samples reveal a striking similarity in distribution patterns of size classes of polymetallic nodules. Due to partial sediment cover, there is a 'fractionation' ...
Clay mineral distribution on tropical shelf: an example from the western shelf of India
(Indian Association of Sedimentology, 1989)
Seventy-five sediment samples collected from the Kerala continental shelf and slope during the 17th and 71st Cruises of RV Gaveshani were analysed by X-ray diffraction for clay mineral content. The distribution of total ...
DDT residues in sediments from the Bay of Bengal
(Springer, 1988)
DDT is one of the organochlorine compounds characterised by its stability for long periods in the environment leading to marked changes in the aquatic ecosystem. This work aims to assess the prevailing levels of DDT and ...
Sediment boron and its relation to sediment properties in a tropical estuary
(Indian Association for Limnology and Oceanography, 1988)
Boron in the sediments of Mandovi estuary varied from 8.0 to 258.0 ppm with an average of 118 ppm. It showed an inverse relation to the texture of sediments and was found to be concentrated in silt and clay fraction with ...
