Our threatened archaeological heritage: A case study from the Tamil Nadu Coast
(Current Science Association, Bangalore, 1997)From the beginning of the Christian era, a number of sites having contact with the Roman world were in existence on the coastal belt of India. There are several indirect references in the literature which suggest that the ... -
Stone anchors from Sindhudurg Fort on the west coast of India
(Academic Press, 1997)Inshore explorations have been carried out in the Malvan region of Maharashtra (India). Present article discusses the triangular and grapnel stone anchors found during the explorations at Sindhudurg and Padamgad Forests. ... -
Multimedia information system for marine archaeology
(NIO, Dona Paula, Goa, India, 1997) -
Grain size studies on the nearshore sediments of Jaigad, Ambwah and Varvada Bays, Maharashtra
(Geological Society of India, 1997)Bivariate plots of the textural parameter data suggest overlapping environments, such as river/beach to JB, beach/dune/river to AB and dune/beach to VB sediments. -
Quaternary radiolarian faunal changes in the tropical Indian Ocean: Inferences to paleomonsoonal oscillation of the 10 degrees S hydrographic front
(Current Science Association, Bangalore, 1997)The northern Indian Ocean is characterized by three distinct surface water masses, i.e. (1) highly saline (greater than 34.5 ppt) Arabian Sea, (2) low saline (less than 34.5 ppt) Bay of Bengal and (3) a moderate salinity ... -
Determination of nodule coverage parameters using multibeam normal incidence echo characteristics: A study in the Indian Ocean
(Taylor and Francis, 1997)A study of the echo peak amplitudes from known nodule areas is initiated to observe the acoustic response for varying nodule abundances and number densities. A statistical study of the peak amplitudes from different nodule ... -
Lithogenic fluxes in the Bay of Bengal measured by sediment traps
(Pergamon, 1997) -
Controls on organic carbon distribution in sediments from the eastern Arabian Sea margin
(Springer, 1997)Sediment cores from the upper continental slope of the eastern Arabian Sea have high organic carbon (OC), CaCO sub(3), and sand content at the top. The values decrease with increasing depth in the Holocene and Upper ... -
Hydrovolcanic activity in the Central Indian Ocean Basin. Does nature mimic laboratory experiments?
(Elsevier, 1997)Classical works in the 1960's on spherules (volcanic, extraterrestrial, cosmic etc.) were carried out in order to distinguish these morphological and compositionally so as to understand their genesis yet, in some cases ... -
Lithological and mineralogical changes observed in a core from the western Bay of Bengal
(Allied, New Delhi (India), 1997)Lithological and mineralogical studies were carried out on sediments from a 650 cm long core from the north western Bay of Bengal at a depth of 2700 m. These studies demarcate a boundary at 380 cm designated as unit 1 from ... -
Record of the Cretaceous magnetic quiet zone: A precursor to the understanding of evolutionary history of the Bay of Bengal
(Current Science Association, Bangalore, 1997)Magnetic study along a transect joining the sites of Ocean Drilling Programme (OPD) keg 116 (1 degrees S, 81 degrees 24'E) and the vicinity of Deep Sea Drilling Project (DSDP) site 218 (7 degrees N, 87 degrees 30'E) revealed ... -
Spreading rate dependent seafloor deformation in response to India-Eurasia collision: results of a hydrosweep survey in the Central Indian Ocean basin
(Elsevier, 1997)The nature of magnetic anomalies and associated ridge-parallel structural lineaments and topographic complexities from an area bounded by latitudes 9 degrees 45'S and 14 degrees 45'S in the Central Indian Ocean Basin (CIOB) ... -
Curstal evolution and sedimentation history of the Bay of Bengal since the cretaceous
(American Geophysical Union, 1997)Multichannel seismic reflection, gravity, magnetic, and bathymetric investigations were made along five latitudinal profiles from the eastern shelf of India of the Andaman shelf and four NW-SE profiles in the Western Basin ... -
Physical properties of a long sediment core from the central Indian Basin
(Geological Survey and Mines Bureau, Dehiwala, Sri Lanka, 1997)In a 7.5 m-long box core, collected at 9 degrees S and 77 degrees E from 5400 m water depth from the Central Indian Basin, geotechnical properties clearly reflect the Plio-Pleistocene boundary. It is marked by a drastic ... -
Diagenetic remobilization of rare earth elements in a sediment core from the central Indian Basin
(NISCAIR, CSIR, 1997)Rare earth elements (REE) distribution in a 36 cm long sediment box core from the Central Indian Basin is studied. REE concentration is generally higher in the upper oxic zone than in intermediate suboxic zone suggesting ... -
Seasonal changes in suspended particulate component in Bombay High oil field (Arabian Sea)
(NISCAIR, CSIR, 1997)Investigation on the influence of seasonal changes in physico-chemical factors on particulate matter in the "Bombay High" region from February'85 to January'86 suggests that dominance of physical factors in monsoon largely ... -
Geomorphology and surficial geology of the western continental shelf and slope of India: A review
(Current Science Association, Bangalore, 1997)Coastal geology and geomorphology of the area and nearshore currents played a significant role in the distribution of placer minerals off Kerala and Maharashtra. Transport and sedeimentation of fine-grained materials at ... -
Shallow stratigraphy and gas-charged sediments in the inner shelf off Redi, west coast of India
(Cent. for Earth Sci. Stud., Cochin (India), 1997)Bathymetric, side scan sonar and seismic studies were conducted in shallow waters of 11-18 m off Redi along central west coast of India to understand the stratigraphy and structural features. Bathymetric contours suggest ... -
Mapping of sea bottom topography over western offshore, India using TOPEX/ERS-1 altimeter data
(Elsevier, 1997)As bathymetry and geoid are highly correlated in the 50-300 km range, the satellite-derived geoid can be used in the mapping of bathymetry. An attempt has been made to assess the accuracy of predicting sea bottom ... -
Seafloor and sediment characteristics in INDEX AREA
(Metal Mining Agency of Japan, 1997)Seafloor surveys and sediment sampling during the INDEX (Indian Deep-Sea Environmental Experiment) studies in the Central Indian Basin, resulted in identification of Test and Reference Areas, as well of establishment of ...
