A note on an occurrence of pseudo-pumice along the beaches of Goa and Karnataka
(CSIR-NISCAIR, 2015)
Clasts showing typical physical features of pumice were found scattered along the beaches of Goa and Karnataka Their chemical composition suggests a large variation in SiO<sub>2</sub> content (69% to 93%), with an unusual ...
Lithospheric stretching and the long wavelength free-air gravity anomaly of the Eastern Continental margin of India and the 85 degree E Ridge, Bay of Bengal
(CSIR-NISCAIR, 2015)
Among the submarine ridge systems in the northern Indian Ocean, the 85 degree E Ridge in the Bay of Bengal is more enigmatic owing to its peculiar anomalous negative free-air gravity. In general, this has been attributed ...
Distribution of Mercury in different abiotic and biotic sectors of the Mandovi-Zuari estuary (Goa)
(CSIR-NISCAIR, 2014)
This study highlights the behaviour of Mercury in the abiotic and biotic segments of the Mandovi-Zuari estuarine system Spatia l, seasonal (Premonsoon and Postmonsoon) and tidal, distribution of THg in dissolved/particulate ...
Characterization of 2004 Indian Ocean tsunami induced deposits along the Chennai coast using magnetic and geochemical techniques
(CSIR-NISCAIR, 2014)
Present study is the applicability of rock magnetic techniques, coupled with geochemical (SiO<sub>2</sub>, Al<sub>2</sub> O<sub>3</sub> , Fe<sub>2</sub>O<sub>3</sub>, CaO, MgO, K<sub>2</sub>O, P<sub>2</sub>O<sub>5</sub>, ...
Land use/land cover changes around Rameshwaram Island, east coast of India
(CSIR-NISCAIR, 2014)
Land-use/land cover changes are studied using the Indian Remote Sensing satellite (IRS-1C, IRS-6) Linear Image Self-scan Sensor (LISS) III data of 1998 and 2010 Coastal land use categories such as sand, vegetation, coral ...
Our changing coastlines
(CSIR-NISCAIR, 1989)
Our coastlines keep alive the sense of continuing creation and of the relentless drive of life In recent years, much has been done both to understand the processes that underlie their creation and to exploit their environment ...
Mineralogy of the carbonate sediments - western continental shelf of India
(Elsevier, 1981)
An X-ray diffraction study of forty-six sediment samples and three oolitic limestone samples from the western continental shelf of India shows that aragonite is the dominant carbonate mineral (99% maximum), followed by ...
Modelling of wave propagation over a submerged sand bar using SWASH
(CSIR-NISCAIR, 2014)
A non-hydrostatic numerical model "SWASH" (Simulating WAves till SHore) is used to study the wave propagation over a submerged sand bar in a wave flume The SWASH model is calibrated and further used to validate the wave ...

This paper was selected for presentation by the OTC Program Committee following review of information contained in an abstract submitted by the author(s). Contents of the paper, as presented, have not been reviewed by the ...
Morphology of an uncharted seamount from Central Indian Basin
(Elsevier, 1989)
The morphology of a seamount at 12 degrees 35'S and 76 degrees 16'E is studied. This conical seamount has a maximum height of 1275 m (water depth 4135 m) and covers an area of about 189 sq km. The maximum basal extension ...
