Some new thoughts on the discovery of ancient Dwarka: A study based on recent marine archaeological exploration off Dwarka, West Coast of India
(Aryan Books, 2005)Archaeological explorations in and around Dwarka have been carried out since 1963. The underwater exploration in Dwarka waters commenced in 1983 to locate submerged habitation, if any. Offshore explorations during last ... -
Marine environmental intimidation to Sundarbans embankments
(Sundarban Affiars Department, WB, 2005)Protection of Sundarbans (West Bengal, India) embankments is an enormous task. There are many external forces that are responsible to destabilize the embankment. River flows with tides is responsible as one of the major ... -
Validation of salinity data from ARGO floats: Comparison between the older ARGO floats and that of later deployments
(The Korean Earth Science Society, 2005)Continued observation of ARGO floats or years (about 4 years) makes the conductivity sensor more vulnerable to fouling by marine life and associated drift in salinity measurements. In this paper, we address this issue by ... -

Bacterial response to contrasting geochemistry in the sediments of central Indian Ocean basin
(Regional Research laboratory, Bhubaneswar, 2005)The latitudinal differences in geochemical and physiographic nature could evoke varied biological/microbiological response in the deep-sea benthic ecosystem of the Central Indian Ocean. Sediment cores have been examined ... -
Detection of pollutants in marine organisms and in the environment as markers of environmental quality
(Pennsilvania Academy of Science, 2005)This chapter presents an overview of various techniques of detection of different types of pollutants such as organochlorine pesticides (e.g. DDT, HCHs, aldrin, dieldrin, endrin, Hepox, heptaclor), polychlorinated biphenyls ... -
Sediment distribution study in the Gulf of Kachchh, India, from 3D hydrodynamic model simulation and satellite data
(Elsevier, 2005)A fully 3D finite difference baroclinic hydrodynamic model 'COSMOS' is applied to the Gulf of Kachchh (GoK) to study tidal variation, ocean currents, residual tidal current, sea surface temperature distribution, etc. The ... -
Impacts on surface productivity during sediment dispersal experiment in Central Indian Basin
(Taylor and Francis, 2005)It is anticipated that in the case of mining of marine minerals, sea floor sediments will be brought up along with the mineral ores and discharged on the surface. These nutrient rich sediments would create a set of different ... -
Microbiology and biochemistry of placer rich beach sediment: Short-term response to small scale simulated mining
(Allied, India, 2005)In order to understand the influence of sand mining on the bacterial community of a placer rich beach ecosystem, a mechanical disturbance was simulated in Kalbadevi beach, Ratnagiri. Core samples from dune, berm, high tide, ... -
Living coccolithophores during the northeast monsoon from the Equatorial Indian Ocean: Implications on hydrography
(Elsevier, 2005)Water samples collected at five stations along 931E section (1 degrees N-4 degrees S) during the northeast monsoon (12-15 February 2000) at five depths (surface, 50, 100, 150 and 200 m) in the eastern equatorial Indian ... -
Monsoon related changes in sea surface productivity and water column denitrification in the Eastern Arabian Sea during the last glacial cycle
(Elsevier, 2005)Sea surface salinity reconstruction for the Holocene and the Last Glacial Maximum (LGM) suggests that the LGM-Eastern Arabian Sea was more saline (by approx.5 psu) than the Holocene due to weakened freshwater flux to the ... -
Dissolved oxygen - A target indicator in determining use of the Gulf of Kachchh waters
(Elsevier, 2005)Spatial and temporal variations of Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) in the Gulf of Kachchh (GoK), India are assessed based on data collected since 1976.DO concentrations in the interior GoK vary ... -
Sediment traps as a new tool for estimation of longevity of planktonic foraminifera
(NCAOR, Goa, 2005)Sediment trap technique provides time series data of sinking particles (faunal and sediment) from surface to bottom of the sea. Besides many other applications, data can also be used to estimate life span of planktonic ... -
Site selection for effluent discharge along the coast using GIS
(ESRI, India, 2005)Geographical Information System (GIS) is used to select a site for industrial effluent discharge along the coastal region. The system is developed to deal with the behavior of the discharged effluent in the coastal waters ... -

Constraints in using Cerium-animaly of bulk sediments as an indicator of paleo bottom water redox environment: A case study from the Central Indian Ocean Basin
(Elsevier, 2005)The total rare earth elements (Sigma REE) abundance along with major and a range of trace element chemistry of twenty-eight sub-sections in a 5 m long sediment core (AAS-05/GC-02) from the Central Indian Ocean Basin shows ... -
Past 100 Ky surface salinity-gradient response in the eastern Arabian Sea to the summer monsoon variation recorded by delta super(18)O of G. sacculifer
(Elsevier, 2005)Northward flowing coastal currents along the western margin of India during winter-spring advect low-salinity Bay of Bengal water in to the Eastern Arabian Sea producing a distinct low-salinity tongue, the strength of which ... -
Stability of the beaches in Nagapattinam District, Tamilnadu, India
(Allied, India, 2005)Beach profiles were carried out in Dec.2003, 2004 and Jan,.2005. Annual profiles of Dec. 2003 and 2004 show a normal trend of beach dynamics. At Poompuhar 63 M sup(3) M sup(1) of sediments are found to be deposited. However, ... -
Surface textures of quartz grains from Goa coast - An application of the scanning electron microscope
