Biogeochemical budgets for Tapi Estuary
(IGBP, 2004)The Tapi estuary (21 degrees 10'N, 72 degrees 40'E) is a tidal estuary originating in the Multai Ghats in Madhya Pradesh at an elevation of 752 m. The 720 km long river, after passing through the 3 states of Madhya Pradesh, ... -
Beach dynamics of an open coast on the west coast of India
(National Institute of Oceanography, India, 2004)In order to study the daily beach dynamics at an open beach in Goa, field investigations were carried out on the beach profiles, breaking wave parameters and long-shore currents for one month each during pre-monsoon and ... -
Oceanographic studies off Beypore Port, west coast of India to locate a dredge dumping site
(Springer, 2004)This study presents the salient results of the oceanographic investigations carried out along the west coast of India to locate a dumping site for the dredged material generated from the capital dredging of the proposed ... -
Submergence of Poompuhar - Study based on underwater explorations and coastal processes
(National Institute of Oceanography, India, 2004)Poompuhar, a flourishing port in the beginning of Christian era played a major role in maritime activities and cultural expansion in the history of India. Sangam literature vividly describe about its location, habitation ... -
Does subterranean flow initiate mud banks off the southwest coast of India?
(Elsevier, 2004)Coastal waters off the southwest coast of India draw special attention because of the occurrence of mud banks at certain locations during southwest monsoon period. The present study puts forward a hypothesis of a subterranean ... -
Development of marine flyash concrete and evaluation of its performance with respect to physico-chemical and biological factors in marine environment
(National Institute of Oceanography, India, 2004)The aim of the research was to develop flyash concrete and assess various factors controlling its durability in the marine environment. Hence the research was planned with the following objectives in mind: (1) Development ... -
Estimation of wave characteristics during hurricane in the Hoian area, central Vietnam
(National Institute of Oceanography, India, 2004)The data of hurricanes crossed the coastline from 14 degree N to 17 degree N, in the vicinity of the Hoian coastline, from 1945 to 2003 were extracted from the National Weather Service, USA. The features such as velocity ... -
Vulnerable areas and adapation measures for sea level rise along the coast of India
(Ministry of Environment and Forests, Government of India, 2004)India has a coastline of about 7500 km with contrasting geological setting. Based upon the available models, global sea level rise of 10-25 cm per 100 year has been predicted due to emission of green house gases. To separate ... -
Isotopic evidences of past upwelling intensity in the Arabian Sea
(Elsevier, 2004)Oxygen and carbon isotopic analyses have been performed on the tests of Globigerina bulloides, Globigerinoides sacculifer, Neogloboquadrina dutertrei and Pulleniatina obliquiloculata to study the delta super(18)O and delta ... -
Tidal influence on suspended sediment distribution and dispersal in the northern Andaman Sea and Gulf of Martaban
(Elsevier, 2004)Surface and water column profiles of suspended matter collected during April-May 2002, and satellite images were used to study factors influencing suspended sediment concentrations (SSCs) and dispersal in the northern ... -
Delineation of high water line and seasonal beach profiling at Kalbadevi Bay, Maharashtra, central west coast of India
(National Institute of Oceanography, India, 2004)Seasonal morphological variations and effect of oceanographic processes such as erosion or accretion along beaches are important to understand the nature of the beach and the cyclic changes occurring during different ... -
New insights into the tectonic evolution of the Andaman basin, northeast Indian Ocean
(Elsevier, 2004)Multibeam swath bathymetry data acquired over an area of about 30 000 km 2 ,together with magnetic and single channel seismic data, have been analyzed to understand the tectonic evolution of the Andaman basin,northeast ... -
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 ...
