Ferromanganese nodules from the Central Indian Ocean Basin
(CRC Press, USA, 2000)In order to delineate a mine site for ferromanganese nodules, extensive surveys were conducted in Central Indian Ocean Basin. Mapping of the basin by multibeam swath bathymetry (Hydrosweep) has revealed many new bottom ... -
Quaternary phosphorites from the continental margin off Chennai, southeast India: Analogs of ancient phosphate stromatolites
(SEPM, Society for Sedimentary Geology, 2000)Pleistocene phosphorites occur on the continental margin off Chennai abundantly in the depth range of 186-293 m. They are associated with outer-shelf glauconites and carbonate skeletals including large shells of molluscs ... -
Influence of marginal highs on the accumulation of organic carbon along the continental slope off western India
(Pergamon, 2000)Twenty five surficial sediment samples were collected from the central western continental margin of India, which consists of diverse physiographic entities, continental slope, shelf margin basin, marginal high, and the ... -
Biostratigraphic analysis of the top layer of sediment cores from the reference and test sites of the INDEX area
(Taylor and Francis, 2000)Radiolarian fossil study in the sediment cores collected during the pre- and postdisturbance cruises of the Environmental Impact Assessment (EIA) Indian Ocean Experiment (INDEX) program of deep sea mining in the Central ... -
Marine geology
(Indian Natl. Sci. Acad., New Delhi-110 002, India, 2000)Significant scientific contributions in Marine Geology in India during the Nineties have been highlighted in this paper. Sediment trap data collected in the Arabian Sea and Bay of Bengal have provided much understanding ... -
Selection of test and reference areas for the Indian Deepsea Environment Experiment (INDEX)
(Taylor and Francis, 2000)The Indian Deepsea Environment Experiment (INDEX) was conducted in the Central Indian Ocean Basin, to assess the effects of a simulated disturbance on the marine ecosystem and to collect data to predict the effects of ... -
Diverse methane concentrations in anoxic brines and underlying sediments, eastern Mediterranean Sea
(Pergamon, 2000)Elevated methane (CH sub(4)) concentrations (128-2692x10 sup(3) nM) occur in the hypersaline anoxic brine pools of Bannock and Urania Basins, eastern Mediterranean Sea, compared to low concentrations (17-80x10 sup(3) nM) ... -
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 ... -
