Tsunami engineering study in India
(Indian Academy of Sciences, 2005)This article describes the need for establishing Tsunami Engineering Study Centers in India. The research groups would study historical tsunami, numerical modeling, field survey, physical experiments, evacuation models, etc. -
Statistical modelling of monthly mean sea level at coastal tide gauge stations along the Indian subcontinent
(NISCAIR, CSIR, 2005)This study investigates the suitability of statistical models for their predictive potential for the monthly mean sea level at different stations along the west and east coasts of the Indian subcontinent. Statistical ... -
IndOBIS, an Ocean Biogeographic Information System for assessment and conservation of Indian Ocean biodiversity
(NISCAIR, CSIR, 2005)Compilation of inventories of components of coastal and marine biodiversity of Indian Ocean is hampered by several factors: low effort by some countries, preference to certain taxon, dwindling taxonomic expertise, low ... -
Coastal and marine biodiversity of India
(NISCAIR, CSIR, 2005)This paper summarizes what is known of the coastal and marine biodiversity of the Indian seas and their various ecosystems, from past literature, museum records and other lesser-known sources of information. The synthesis ... -
Spatial variations of DMS, DMSP and phytoplankton in the Bay of Bengal during the summer monsoon 2001
(Elsevier, 2006)Data on the distribution of Dimethylsulphide (DMS) and dimethylsulphoniopropionate (DMSP) in relation to phytoplankton abundance in different oceanic environments is important to understand the biogeochemistry of DMS, which ... -
Signature of terrestrial influence on nitrogen isotopic composition of suspended particulate
(Indian Academy of Sciences, 2005)Nitrogen concentration and its isotopic composition in surface suspended matter have been measured at 24 different locations during the post-monsoon season in the Bay of Bengal. In general, the stable nitrogen isotopic ... -
Seafloor spreading magnetic anomalies south off Sri Lanka
(Elsevier, 2006)Results obtained from compilation and reinterpretation of about 21,200 line km of bathymetry, magnetic and satellite gravity data between 10oS to 10oN latitudes and 75 to 90oE longitudes south off Sri Lanka are presented ... -
Studies on the pore water sulfate, chloride and sedimentary methane to understand the sulfate reduction process in the eastern Arabian Sea
(Indian Academy of Sciences, 2006)Sediment cores (~5 m length) from ten stations collected in the water depths of 2665-3210 m in the eastern Arabian Sea were studied for pore water sulfate (SO42-), chloride (Cl-) and lighter-hydrocarbons (methane: C1, ... -
The terrace like feature in the mid-continental slope region off Trivandrum and a plausible model for India-Madagascar juxtaposition in immediate pre-drift scenario
(Elsevier, 2006)Bathymetry of the southwestern continental margin of India reveal the presence of an anomalous terrace like feature in the mid continental slope region off Trivandrum. The genesis of this terrace of large areal extent ... -

Factors affecting the occurrence of Porphyra vietnamensis Tanaka & Pham-Hoang Ho along the Goa coast
(Indian Academy of Sciences, 2005)Porphyra vietnamensis Tanaka & Pham-Hoang Ho occurs in the intertidal region of the Goa coast, during mon-soon months from June to September. The growth and distribution patterns of P. vietnamensis populations along the ... -
Tsunamis: A large-scale earth and ocean phenomena
(Indian Academy of Sciences, 2005)Tsunamis are surface gravity waves that are triggered due to perturbation of the ocean floor. The tsunamis that occurred in the Indian Ocean on 26 December 2004 were due to an earthquake off the coast of Sumatra. Sea level ... -
Biological productivity, terrigenous influence and noncrustal elements supply to the Central Indian Ocean Basin: Paleoceanography during the past approx. 1 Ma
(Indian Academy of Sciences, 2005)A 2 m-long sediment core from the siliceous ooze domain in the Central Indian Ocean Basin (CIOB; 13 degrees 03'S: 74 degrees 44'E; water depth 5099 m) is studied for calcium carbonate, total organic carbon, total nitrogen, ... -
Compositional variation and genesis of ferromanganese crusts of the Afanasiy-Nikitin Seamount, Equatorial Indian Ocean
(Indian Academy of Sciences, 2005)Eight ferromanganese crusts (Fe-Mn crusts) with igneous and sedimentary substrates collected at different water depths from the Afanasiy-Nikitin Seamount are studied for their bulk major, minor and rare earth element ... -
Seasonal variability of physico-chemical characteristics of the Haldia channel of Hooghly estuary, India
(Indian Academy of Sciences, 2005)Physical and chemical characteristics of the Hooghly estuary during winter (December 1997 January 1998), summer (May 1998) and post-monsoon (November 1998) seasons have been studied. Salinity varied spatially and temporally ... -
Modelling Ballast Water Transport
(National Institute of Oceanography, Goa., 2002)Ballast water discharges in the coastal environs have caused a great concern over the recent periods as they account for transporting marine organisms from one part of the world to the other. The movement of discharged ... -
Breathing Cochin backwaters: Need for conservation
(National Institute of Oceanography, Goa., 2002)The foregoing account, it is evident that Vembanad Lake, including the Cochin backwaters is undergoing man-made shrinkage, at an alarming rate and a rough estimate of similar plans in the future shows that by the turn ... -
Butyltin compounds in biofilm and marine organisms from the Dona Paula Bay, west coast of India
(TERI Press, India, 2006)Biofilm, fish, oyster, mussel, and clams were collected from the Dona Paula Bay, west coast of India. These samples were analysed for butyltin derivatives. In the Dona Paula Bay, total butyltins varied from 21 to 89 ng/l ... -
