Sediment transport and depth variation study of the Gulf of Kutch using remote sensing
(Taylor and Francis, 2003)Ocean Colour Monitor (OCM) data gathered onboard Indian Remote Sensing satellite (IRS P4), in eight VNIR bonds covering Gulf of Kutch and adjoining regions were digitally processed using an image processing system. False ... -
Longshore sediment transport rate-measurement and estimation, central west coast of India
(Elsevier, 2003)Measurements of the longshore sediment transport rate (LSTR) along the surf zone at a 4-km-long beach on the central west coast of India were made over a 4-month period. During the study, both the lateral and vertical ... -
Carbon and oxygen isotope time series records of planktonic and benthic foraminifera from the Arabian Sea: Implications on upwelling processes
(Elsevier, 2003)Oxygen and carbon isotopic analyses have been performed on the tests of Globigerina bulloides and Pulleniatina obliquiloculata (planktonic foraminifera) and Uvigerina excellens (benthic foraminifer) to study the evolution ... -
Quantitative seafloor characterization using angular backscatter data of the multi-beam echo-sounding system - Use of models and model free techniques
(Allied, India, 2003)For quantitative seafloor roughness characterization and classification using multi-beam processed backscatter data, a good correlation is indicated among the power law parameters (composite roughness model) and hybrid ANN ... -
Himalayan sedimentary pulses recorded by silicate detritus within a ferromanganese crust from the Central Indian Ocean
(Elsevier, 2003)A Central Indian Ocean deep-water seamount hydrogenous ferromanganese crust (SS663-Crust) contains variable (7-23%) amounts of detrital material (silicate-detritus). Taking into account the growth rate of the authigenic ... -
Hydrothermal petroleum in the sediments of the Andaman Backarc Basin, Indian Ocean
(Elsevier, 2003)Recent sediments of he Andaman Backarc Basin, Indian Ocean, between the Andaman Nicobar islands and the Malay Peninsula have been analyzed for biomarker lipids. Three cores were selected: one each from the fault zone in a ... -
Sea-floor classification using multibeam echo-sounding angular backscatter data: A real-time approach employing hybrid neural network architecture
(IEEE, 2003)The presently studied numerical model, e.g., composite roughness, is successful for the purpose of sea-floor classification employing processed multibeam angular backscatter data from manganese-nodule-bearing locations of ... -
Significance of relic carbonate deposits along the central and southwestern margin of India for late Quaternary environmental and sea level changes
(Elsevier, 2003)Environmental and sea level indicators were investigated using dredge samples from late Quaternary carbonate deposits along the shelf break between Goa and Cape Comorin, India. Geomorphic features in the area were identified ... -
Deep-sea polymetallic nodule mining: Challenges ahead for technologists and environmentalists
(Taylor and Francis, 2003)Although, offshore mining for mineral wealth is not required at present, it may be the only alternative in the future due to the continuous growing demand for certain metals that have no or limited land deposits. Risk ... -
Two layers of Australian impact ejecta in the Indian Ocean
(Meteoritical Society, 2003)Only 2 Australian tektites have been found in the Indian Ocean, and both are associated with surficial sediments. Cores from both locations are collected, where the tektites have been reported. The microtektites in these ... -
Clay minerals and Sr-Nd isotopes of the sediments along the western margin of India and their implication for sediment provenance
(Elsevier, 2003)Mineralogy and Sr-Nd isotopic composition of the less than 2-m fraction of the Holocene and late Pleistocene sediments from 12 gravity cores collected along the western margin of India were used to delineate the provenance ... -
Biogeochemical characteristics of sedimenting particles in Dona Paula Bay, India
(Elsevier, 2003)Sedimenting particles were collected at weekly intervals from October to May during 1995-1997 at a station in the coastal waters of Dona Paula Bay on the west coast of India. Sedimenting particles were analysed for ... -
Structure and evolution of the Afanasy Nikitin seamount, buried hills and 85 degrees E Ridge in the northeastern Indian Ocean
(Elsevier, 2003)Geophysical data of the Afanasy Nikitin seamount (ANS), partly buried hills and 85 degrees E Ridge in the northeastern Indian Ocean were studied together with published seismic refraction results to understand genesis and ... -
Geographical information system analysis for oceanographic parameters in the coastal waters of Goa, India - A case study
(ESRI, India, 2003)A geographical information system (GIS) is used to create oceanography database and to do the spatial analysis of physical, chemical and biological characteristics of the coastal waters of Goa, India. Vector maps depicting ... -

(National Institute of Oceanography, India, 2003) -
Estimation of wind speed and wave height during cyclones
(Elsevier, 2003)Wave and wind characteristics based on the cyclones, in the vicinity of the Nagapattinam coastline (east coast of India) were estimated. In all, 11 cyclones have crossed near the study region during 1960-1996. For the four ... -
Modeling of sediment transport along Mangalore coast using mike 21
(Allied, India, 2003)The objective of the present study is to understand the sediment transport along Mangalore Coast and to quantify the sediment transport rates. The data used in the present study includes Wave, Wind, Tide, Naval Hydrographic ... -
Performance of Honeywell silicon pressure transducers
(Allied, India, 2003)Simultaneous calibration of three Honeywell pressure transducers (PPTR) at four ambient temperatures have been carried out using a novel static calibration system developed in-house. Calibration results indicated that ...
