Characterizing Indian Ocean manganese nodule-bearing seafloor using multi-beam angular backscatter
(Springer, 2004)Application of quantitative angular backscatter modelling to manganese nodule-bearing areas of the Central Indian Ocean Basin (CIOB) has been initiated at NIO during the year 1998. Studies were aimed to establish the ... -
Potential natural gas hydrates resources in Indian Offshore areas
(AAPG, 2004)Large amount of multi-channel seismic reflection data was acquired by oil industry for exploration of hydrocarbon in the Indian Deepwater basins, beyond 400m isobath. These data were examined for BSRs, blanking above BSRs, ... -
Coastal ecosystem and environmental aspects of placer mining
(Allied, India, 2004)The world demand for mineral raw material is expected to increase more than threefold with the increase in population and the industrilization. Though, India's mineral resources generally appear to be sufficient to meet ... -
Ammolagena clavata (Jones and Parker, 1860), an agglutinated benthic foraminiferal species - first report from the Recent sediments, Arabian Sea, Indian Ocean region
(Cushman Foundation for Foraminiferal Research, 2004)The rare presence of the agglutinated foraminiferal species Ammolagena clavata is presented for the first time from the Recent sediments of the Indian Ocean region. This species has previously been reported in Recent ... -
Seafloor classification using echo- waveforms: A method employing hybrid neural network architecture
(IEEE, 2004)This letter presents seafloor classification study results of a hybrid artificial neural network architecture known as learning vector quantization. Single beam echo-sounding backscatter waveform data from three different ... -
Atypical delta sup(13) C signature in Globigerina bulloides at the ODP site 723A (Arabian Sea): Implications of environmental changes caused by upwelling
(Elsevier, 2004)Production of Globigerina bulloides generally increases during upwelling in the tropical ocean and, in particular, during southwest monsoon season in the Arabian Sea. We studied the delta sup(13) C signatures of Globigerina ... -
Pressure gauge experiments in India
(UNESCO, 2004)Pressure measurements made in differing turbid water bodies and turbulent clear-water bodies have led to the inference that the effective mean-depth in situ density value, Row eff, of these water bodies is less than the ... -
An interactive software package for validating satellite data
(Universidad de Concepcion, 2004)Earth observation satellite launched in the last three decades have made vital contributions to the understanding of the planet. The earth system consisting of land, oceans and atmosphere is linked together by a number of ... -
"Nonlinear coupled dynamic response of offshore spar platforms under regular sea waves" by A.K. Agarwal and A.K. Jain. Ocean Engineering 30; 2003; 517-555
(Elsevier, 2004)This paper is a comment on the paper written by A.K. Agarwal and A.K. Jain, published in Ocean Engineering, 30; 2003; 517-555 -
Neural networks for estimation of ocean wave parameters
(National Institute of Oceanography, India, 2004)Ocean wave parameters play a significant role in the design of all coastal and offshore structures. In the present study, neural networks are used to estimate various ocean wave parameters from theoretical Pierson-Moskowitz ... -
Installation and operation manual on sea level gauge (Model: NIO_Ghana_2004)
(National Institute of Oceanography, India, 2004)NIO sea level gauge is a pressure-based gauge that operates on 12 volts battery. The pressure-sensing element used in this gauge is a piezo-resistive programmable semiconductor transducer that provides pressure samples in ... -
Suspended sediment profiles derived from spectral attenuation coefficients measurements using neural network method
(National Institute of Oceanography, India, 2004)Suspended sediment in water plays a major role in the operations of ports and harbor. Here we report a model to be used with an optical instrument that is primarily used for the measurements of inherent optical properties. ... -
Bottom mounted seabed mooring frame for high current field
