Sonograph patterns of the central western continental shelf of India
(Tirunelveli: JCSONLINE, 1989)
Side scan sonar and bathymetric surveys were conducted on the central western continental shelf of India. The sonographs portray a smooth, relatively featureless inner shelf, up to a depth less than 40-50 m, which is covered ...
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. ...
Lack of cross-shelf transport of sediments on the western margin of India: Evidence from clay mineralogy
(Tirunelveli: JCSONLINE, 1989)
The distribution of clay minerals on the inner shelf, outer shelf and in a 6 month sediment trap on the western continental shelf of India has been studied. Marked compositional differences in the inner shelf clays ...
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 ...
Seismic stratigraphy of Ongole-Paradip continental shelf, east coast of India
(Springer, 1989)
High resolution seismic data over the continental shelf off Ongole to Paradip, east coast of India (14 degrees 30 minutes N to 12 degrees 30 minutes N) indicates that the seismic stratigraphy within the top 100 metres of ...
Planktonic foraminifera from core tops of western equatorial Indian Ocean
(Calcutta: Geological Survey of India, 1989)
A set of seven core tops from western equatorial Indian ocean were analysed for planktonic foraminifera, which has yielded 20 planktonic foraminiferal species. Among them Globorotalia menardii, Globigerinoides sacculifer ...
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 ...
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' ...
