Abandoned Paleocene spreading center in the northeastern Indian Ocean: evidence from magnetic and seismic reflection data
(Elsevier, 2000)Magnetic data from the northeastern Indian Ocean reveal east-west trending magnetic lineations 28 through 34, an abandoned spreading center (ASC) and part of the Cretaceous Magnetic Quiet Zone (CMQZ), which are used to ... -
Distribution and composition of verdine and glaucony facies from the sediments of the western continental margin of India
(Society for Sedimentary Geology, Tulsa, USA, 2000)Investigations on green grains from sediments of the western continental margin of India, between Ratnagiri and Cape Comorin, (water depth 37-330 m) indicate the presence of verdine and glaucony facies. Verdine facies ... -
A short discussion on artifact creating conditions using multibeam bathymetric systems in a highly reflecting and smooth bottom
(NIO, Dona Paula, Goa (India), 2000)Using multibeam system, artifact creating conditions are dominant when functioning in highly reflective and flat bottom areas. This simulation study manifests the causes responsible for creating such conditions which ... -
Morphological features of Co-rich manganese deposits and their relation to seabed slopes
(Taylor and Francis, 2000)The morphological features associated with Co-rich manganese deposits, the size variations of nodules, and the occurrence of different substrates have been analyzed, to evaluate the influence of various seabed slope angles ... -
Influence of sedimentation on the geomorphology of the northwestern continental margin of India
(Taylor and Francis, 2000)Based upon the analysis of about 10,000 line km of echosounding and bathymetric data and variations in mass accumulation rate along the NW continental margin of India (between Kori creek and Mumbai), which has deduced in ... -
Assessment of impact on seafloor features in INDEX area
(Taylor and Francis, 2000)Observations on seafloor features from subbottom profiling and seabed photography data show that the undisturbed and natural conditions before the benthic disturbance undergo a substantial change after operation of the ... -

Spitbase of west coast of India: Potential appraisal
(Museo Geologico di Bologna, 2000)Spectacular spits of different sizes and variety of shapes bordering west coast of India were mapped with remote sensing techniques. By gathering information on geomorphological and locational parameters of spits, "SPITBASE", ... -
Settling fluxes of U- and Th-series nuclides in the Bay of Bengal: Results from time-series sediment trap studies
(Pergamon, 2000)A two-year (1990-1991) collection of sediment trap samples from three locations in the Bay of Bengal was analyzed for Al, Ca and U- and Th-series nuclides to obtain their annual fluxes and pattern of deposition. The ... -
Rare-earth elements and uranium in phosphatic nodules from the continental margins of India
(Society for Sedimentary Geology (SEPM), Tulsa, USA, 2000)A sediment core collected from a bathymetric high off Goa on the western continental margin of India has yielded phosphatic nodules at various subsurface depths (at 110, 150, 305 355, 435, 500, 505 and 525 cm). The nodules ... -
Change detection studies in and around Kolleru Lake using high resolution data
(NIO, Dona Paula, Goa (India), 2000)Kolleru is one of the largest freshwater lake situated in Krishna and West Godavari districts of Andhra Pradesh state, India, having an area of 198.92 sq. km. Agriculture was practiced on the lake surrounding areas. During ... -
Consolidation and strength properties of calcareous sediments from Kaneohe and Kailua Bays, Hawaii
(International Society of Offshore and Polar Engineers (ISOPE), 2000)Shallow-water sediments found near the shorelines of Kaneohe and Kailua bays on the island of Oahu, an area that has seen continuous development over the last 40 years, were tested to determine the influence of terrigenous ... -

A comparative study of Pleistocene phosphorites from the continental slope off western India
(Blackwell, 2000)Two types of phosphorite recovered from the continental slope off western India are described. The first type, phosphorite 1, comprises a hard, grey nodule composed of carbonate fluorapatite (CFA) and calcite as major ... -

Increased particle fluxes at the INDEX site attributable to simulated benthic disturbance
(Taylor and Francis, 2000)Particle fluxes were measured 7 m above the sea bottom during the predisturbance, disturbance, and postdisturbance periods by using time series sediment traps attached to seven deep-sea moorings deployed in the INDEX ... -
Geotechnical properties of surface sediments in the INDEX area
(Taylor and Francis, 2000)As a part of the environmental impact assessment studies, geotechnical properties of sediments were determined in the Central Indian Basin. The undrained shear strength and index properties of the siliceous sediments were ...
