Sediment dispersal during ne monsoon over northern Bay of Bengal: Preliminary results using IRS-P4 OCM data
(NIO, Dona Paula, Goa (India), 2000)False Color Composite (FCC) from the sequential satellite images of Indian Remote Sensing Satellite IRS-P4 OCM (bands around 443, 555, and 845 nm) together with sea truth data acquisition at 42 stations along the Orissa ... -
Foraminiferal studies from the west coast of India: Relevance to PAGES program
(Indian Institute of Tropical Meteorology, Pune, 2000) -
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 ... -
Opportunities in the EEZ

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 ... -
Sediment dispersal in the macro tidal Gulf of Kachchh, India
(NIO, Dona Paula, Goa (India), 2000)Studies of sub-bottom physiography, tidal parameters and characteristics of the sediment in the Gulf of Kachchh have been made. The tidal range becomes progressively higher in the inner gulf with associated high magnitude ... -
Remote assessment of net shore drift along the west coast of India
(NIO, Dona Paula, Goa (India), 2000)Space borne images were analyzed to examine direction, amount and behavior of long-shore drift and its contribution towards deciding areas vulnerable to coastal erosion and accretion along the West Coast of India. Long-term ... -
Environment and deep-sea mining: A perspective
(Taylor and Francis, 2000)As the quest for deep-sea mineral resources is gaining momentum, environment and ocean mining have become important aspects of study. Because many of these deposits occur in international waters, the concern for environmental ... -
Magnetic and bathymetric investigations over the Vema Region of the Central Indian Ridge: Tectonic implications
(Elsevier, 2000)Magnetic and bathymetric data were collected along N50 degrees E profiles in the Vema Region (7-12 degrees S, 64-70 degrees E) across five ridge segments of the Central Indian Ridge (CIR). Anomalies up to A5 (10 Ma), ... -
Late-Quaternary variations in clay minerals along the SW continental margin of India: Evidence of climatic variations
(Springer, 2000)Down-core variations in illite, chlorite, smectite and kaolinite (the major clays) in two sup(14)C-dated cores collected along the SW continental margin of India show that illite and chlorite have enhanced abundance during ... -
Growth response of a deep-water ferromanganese crust to evolution of the Neogene Indian Ocean
(Elsevier, 2000)A deep-water ferromanganese crust from a Central Indian Ocean seamount dated previously by sup(10)Be and sup(230) Th sub(excess) was studied for compositional and textural variations that occurred throughout its growth ... -
Distribution of grain size and clay minerals in sediments from the INDEX area, central Indian Basin
(Taylor and Francis, 2000)The granulometry of 21 box core sediments from five selected sites in the Central Indian Basin (CIB) have been studied to understand the sediment size characteristics in the Pioneer area before the benthic disturbance ... -
Seabottom characterization using multibeam echosounder angular backscatter: An application of the composite roughness theory
(IEEE, 2000)Composite roughness theory is used to characterize Southern Ocean bottom backscatter (multibeam) data. Spectral parameters based on Helmholtz-Kirchhof's theory (1) are determined from measured near-normal incidence values. ... -
Microscale response of sediment variables to benthic disturbance in the Central Indian Ocean Basin
(Taylor and Francis, 2000)The response of sediment bacteria and biochemical variables to benthic disturbance was investigated in the Central Indian Ocean Basin from cores at nine stations. Generally, bacterial density and biochemical variables ... -
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 ... -
Evaluation and performance enhancement of a pressure transducer under flows, waves, and a combination of flows and waves
(American Meteorological Society, 2000)The performance of a pressure transducer, with its inlet attached to differing hydromechanical front ends, has been evaluated in flow flume and wave flume experiments in which laminar and turbulent flows, and regular ... -
Applications of doppler effect in navigation and oceanography
(Marcel Dekker, N.Y., USA, 2000)The Doppler effect is the change in frequency of the received sound waves/electromagnetic waves when there is a relative motion between the transmitter and the receiver of these waves. This effect is used for diverse ... -
Very high resolution satellite data: New challenges in image analysis
(NIO, Dona Paula, Goa (India), 2000)Early years of coming century will see a large number of satellites with very high spatial resolution reaching beyond 1 m in the visible range of electromagnetic spectrum. Such images will come very close to giving a ...
