Spit evolution and shore drift direction along south Karnataka coast, India
(Museo Geologico di Bologna, 1991) -
Petroleum hydrocarbon concentration in surface sediments in continental shelf region along the central west coast of India
(Philippine Society of Sanitary Engineers, and the Asian Recycling Association, 1991)Gas chromatography revealed that nonpolar material extracted from surface sediments collected along the northern west coast of India was originated from petroleum hydrocarbon residue. Petroleum hydrocarbon levels as ... -
Manganese nodules in the Exclusive Economic Zone of Mauritius
(Taylor and Francis, 1991)The distribution of manganese nodules in the Exclusive Economic Zone of the island nation Mauritius was delineated during cruise SK-35 of ORV Sagar Kanya in 1987. The areas surveyed included Saya de Malha and Nazareth ... -
Nearshore magnetic anomalies of inner shelf of Bhimunipatnam-Pudimadaka, east coast of India
(Indian Society of Earth Sciences, Calcutta, 1991)Analysis of marine magnetic data of the nearshore marine environment between Bhimunipatnam and Pudimadaka, on the East Coast of India indicate charnockite intrusions in the innershelf in certain areas. From the analysis ... -
Longshore sediment transport along the Indian coast
(NISCAIR, New Delhi, 1991)An empirical sediment transport model has been developed based on longshore energy flux equation. Ship reported waves, published in Indian Daily Weather Reports, are compiled for 19 y and used for estimation of sediment ... -
Application of acoustic, magnetic and electromagnetic systems in marine archaeology
(NIO, Goa, 1991)The importance of integrated geoscientific studies is reiterated for underwater archaeological exploration. Geophysical systems applied for the detection of artefacts, ancient places and underwater sites/objects are explained ... -
Petrography and chemistry of basalts from the Carlsberg ridge
(Geological Society of India, 1991)The petrography of the basalts collected in dredge hauls from the Carlsberg Ridge (3 degrees 37'N and 64 degrees 07'E) show systematic variations in their textural and mineralogical assemblages, from an outermost vitreous ... -
Internal constitution of manganese nodules from the Central Indian Ocean basin
(NISCAIR, New Delhi, 1991)Morphological, chemical, physical and acoustic properties of Mn-nodules in the the Indian Ocean are inter-linked and depend much on local and regional oceanic environments. These nodules are anisotropic and sound propagation ... -
Marine geophysical surveys off Kaverppattinam for archaeological investigations
(Society for Marine Archaeology, Goa, 1991)Marine geophysical surveys were carried out in Madras, 1990 in the offshore regions of Tranquebar and Kaverippattinam covering the area between 5 and 15 m water depth. In addition to several isolated objects, a continuous ... -
Buried late Pleistocene fluvial channels on the inner continental shelf off Vengurla, west coast of India
(Coastal Research Foundation, 1991)Analysis of echosounding, side-scan sonar and shallow seismic data collected west of Burnt islands off Vengurla, west coast of India, revealed a featureless seabed, thicknesses of subsurface layers, and presence of buried ... -
Marine positioning for exploration of offshore resources
(Marine Technology Society, Rosenstiel School of Marine and Atmpospheric Science, Univ. of Miami, 1991) -
Petrology of rift-related basalts at Bombay High waters, Arabian Sea
(NISCAIR, New Delhi, 1991)Tholeiitic basalts obtained in 6 cores from Bombay High Region (Maharashtra, India), at depths of 860-2550 m below the seabed, are of low K and high Fe types. SiO sub(2) varies from 45.68 to 50.72%, K sub(2)O 0.09 to 0.69%, ... -
Clay mineral distribution in the continental shelf and slope off Saurashtra, West coast of India
(NISCAIR, New Delhi, 1991)Clay mineral distribution in the sediments of the west coast of India indicates that the illite and chlorite-rich sediments, derived from the Indus, occupy the continental shelf of the northern part of the Gulf of Kutch. ... -
New ichthyoliths from ferromanganese crusts and nodules from the Central Indian Ocean Basin
(Micropaleontology Press, 1991)Ferromanganese encrusted hardgrounds, their intraclasts and the nuclei of manganese nodules collected from the Central Indian Ocean basin have yielded plentiful numbers of ichthyoliths. Forty well-knon ichthyoliths, one ... -
