Application of oxidative stress indices in natural populations of Perna viridis as biomarker of environmental pollution
(Elsevier, 2009)Oxidative stress indices were measured in gills and digestive glands of Perna viridis collected from three coastal locations in Goa i.e., Bambolim, Marmugao Harbour and Malim. In addition to lipid peroxidation, the activities ... -
Seasonal dimethylsulfoniopropionate (DMSP) variability in Dona Paula Bay
(Elsevier, 2009)Data on temporal variations of total dimethylsulfoniopropionate (DMSPt) and the environmental factors that influence DMSPt concentrations are important in understanding the biogeochemical cycling of organic sulfur compounds. ... -
Biochemical composition of the marine conditioning film: Implications for bacterial adhesion
(Taylor & Francis, 2009)The conditioning film formed on glass panels was analysed for total carbohydrates (CFCHO), total proteins (CFP) and total uronic acids (CFURA). The influence of these compounds on the adhesion of three marine bacterial ... -
Surface and subsurface geostrophic current variability in the Indian Ocean from altimetry
(Taylor & Francis, 2009)Geostrophic currents were calculated at the surface and subsurface levels in the Indian Ocean using satellite altimetry data from TOPEX/POSEIDON and Jason-1, a geoid obtained from the GRACE mission, and historical hydrographic ... -
Report of epibiont Thecacineta calix (Ciliophora: Suctorea) on deep sea Desmodora (Nematoda) from the Andaman Sea, Indian Ocean
(Marine Biological Association of the United Kingdom, 2010)Suctorian epibionts Thecacineta calix attached on the cuticle of nematodes Desmodora sphaerica and D. pontica are reported here from the deep sea hexactinellid sponge Pheronema sp. from the Andaman Sea (Indian Ocean). The ... -
Threshold effects in semi-enclosed marine systems
(Island Press, 2009)The natural history of the twentieth century documents dramatic changes in many ecological systems, mostly due to the influence of the expansion of human civilization. Semi-enclosed marine systems (SEMSs) are no exception ... -
Limno-tolerant bacteria govern nitrate concentration in Mandovi estuary, India
(Elsevier, 2009)The spatial and temporal abundances of limno-tolerant and halo-tolerant bacteria were investigated in the tide-dominated Mandovi estuary along the west coast of India. These investigations were carried out in relation to ... -
Copper and nickel speciation in mine effluents by combination of two independent techniques
(Elsevier, 2009)To control potentially toxic metals in water resources it is necessary to know metal speciation and changes in the metal speciation that occur after aqueous effluents containing metals are discharged into freshwaters. This ... -
Gametogenic development and spawning of the mud clam, Polymesoda erosa (Solander, 1876) at Chorao Island, Goa
(Taylor & Francis, 2009)The reproductive cycle of Polymesoda erosa was studied over a 12 - month period from July 2004 to July 2005 at Chorao Island, Goa, India. Macroscopic observation revealed that Polymesoda erosa is dioecious and gametogenic ... -
Low-scale foreshore morphodynamic processes in the vicinity of a tropical estuary at Honnavar, central west coast of India
(Coastal Education and Reserch Foundation, 2009)Low-scale foreshore morphodynamic processes in the vicinity of the Sharavati estuary at Honnavar, central west coast of India, are discussed in this paper based on the wave refraction analyses, sediment characteristics, ... -
Provenance signature of pre-cambrian and mesozoic rocks in the nearshore placers of Konkan, central west coast of India
(Taylor & Francis, 2009)Heavy mineral studies of the nearshore placer deposits of the Konkan Coast reveal a dominant assemblage comprised of garnet and kyanite along with other accessory minerals like epidote, olivine and rutile. The heavy mineral ... -
Tandem Wittig-ene reaction approach to kainic acid
(American Chemical Society, 2009)The first example of a tandem Wittig-intramolecular ene reaction approach and its application toward the synthesis of kainic acid is reported. The synthetic pathway involves conversion of prenyl bromide into phosphorane ... -
Vulnerability of semi-enclosed marine systems to environmental disturbances
(Island Press, 2009)Semi-enclosed marine systems (SEMSs) are impacted on time scales ranging from the very short (days or less) to the very long (decades and beyond) by many of the same forces and stresses as other components of the Earth ... -
Biogeochemical characteristics of the surface sediments along the western continental shelf of India
(Taylor & Francis, 2009)Surface sediments from the western continental shelf of India were analysed for total organic carbon (TOC), total nitrogen (TN), total hydrolysable carbohydrates (TCHO) and proteins (PRT) during the late summer monsoon ... -

A survey of perfluorinated compounds in surface water and biota including dolphins from the Ganges River and in other waterbodies in India
(Elsevier, 2009)Despite the reports of the occurrence of perfluorochemicals (PFCs) in industrialized nations, information on PFCs in less industrialized countries is meager. In the present study, concentrations and profiles of PFCs were ... -
RAMA: The Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (including supplement)
(American Meteorological Society, 2009)The Indian Ocean is unique among the three tropical ocean basins in that it is blocked at 25 degrees N by the Asian landmass. Seasonal heating and cooling of the land sets the stage for dramatic monsoon wind reversals, ... -
Evidence of paleo-cold seep activity from the Bay of Bengal, offshore India
(American Geophysical Union, 2009)Evidence of paleo–cold seep associated activities, preserved in methane-derived carbonates in association with chemosynthetic clams (Calyptogena sp.) from a sediment core in the Krishna-Godavari basin, Bay of Bengal is ... -
Archaeology of the western Saurashtra Coast: Post-urban Harappan era
