Simulating the daily discharge of the Mandovi River, west coast of India
(Taylor & Francis, 2012)A hydrological modelling framework was assembled to simulate the daily discharge of the Mandovi River on the Indian west coast. Approximately 90% of the west-coast rainfall, and therefore discharge, occurs during the summer ... -
Distribution of REEs and yttrium among major geochemical phases of marine Fe–Mn-oxides: Comparative study between hydrogenous and hydrothermal deposits
(Elsevier, 2012)Mineralogy and geochemistry of the ferromanganese oxides collected from two seamounts in the Andaman Sea have been investigated with special reference to the solid phase partitioning behavior of rare earth elements (REEs). ... -
Carbohydrate-degrading bacteria closely associated with Tetraselmis indica: Influence on algal growth
(Inter-Research, 2012)The interactions between the algal species Tetraselmis indica and strains of bacteria are examined. Three bacterial strains were isolated and sequence analysis of the 16S rDNA indicated that the organisms belong to the ... -
Seismic characterization of hydrates in faulted, fine-grained sediments of Krishna-Godavari basin: Unified imaging
(American Geophysical Union, 2012)A combination of diffusion and advection in fine grained sediments can create a patchy Bottom Simulating Reflector (BSR) which has little to no apparent correlation with the overlying hydrate distribution. Using 2D seismic ... -
Petrographic studies on a newly discovered Indo-Arabian stone anchor from the Gulf of Kachchh, Gujarat: Implications for source area
(Current Science Association, 2012)Finding of stone anchors in the onshore and offshore regions of India points to maritime contacts with neighbouring countries. This communication reports a new Indo-Arabian type stone anchor recovered from a depth of 53 m ... -
Population genetic structure of skipjack tuna Katsuwonus pelamis from the Indian coast using sequence analysis of the mitochondrial DNA D-loop region
(Fisheries Society of the British Isles, 2012)Genetic structure of skipjack tuna Katsuwonus pelamis from the Indian region was investigated using sequence data of mitochondrial DNA (mtDNA) D-loop region. A total of 315 individuals were sampled from six major fishing ... -
Processes of 30–90 days sea surface temperature variability in the northern Indian Ocean during boreal summer
(Springer-Verlag, 2012)During summer, the northern Indian Ocean exhibits significant atmospheric intraseasonal variability associated with active and break phases of the monsoon in the 30–90 days band. In this paper, we investigate mechanisms ... -
Aliidiomarina haloalkalitolerans sp. nov., a marine bacterium isolated from coastal surface seawater
(Springer, 2012)A novel Gram-negative, rod shaped, motile, non-sporing strictly aerobic bacterium, designated strain AK5 sup(T), was isolated from a sea water sample collected near Visakhapatnam coast, Bay of Bengal, India. Colonies on ... -
Comparison of tropical cyclogenesis indices on seasonal to interannual timescales
(Springer-Verlag, 2012)The performances of four cyclogenesis indices against observed tropical cyclone genesis on a global scale over the period 1979–2001 are evaluated. These indices are: the Genesis Potential Index; the Yearly Genesis Parameter; ... -
Validation of satellite-derived tropical cyclone heat potential with in situ observations in the North Indian Ocean
(Taylor & Francis, 2012)Tropical cyclone heat potential (TCHP) is an important ocean parameter influencing cyclones and hurricanes. The best approach for computing TCHP is to use in situ measurements. However, since in situ data have both spatial ... -
Nitrogen-limited mangrove ecosystems conserve N through dissimilatory nitrate reduction to ammonium
(Nature Publishing Group, 2012)Earlier observations in mangrove sediments of Goa, India have shown denitrification to be a major pathway for N loss However, percentage of total nitrate transformed through complete denitrification accounted for less than ... -
Molecular diversity of fungi from marine oxygen-deficient environments (ODEs)
(Springer, 2012)Molecular diversity surveys of marine fungi have demonstrated that the species richness known to date is just the tip of the iceberg and that there is a large exent of unknown fungal diversity in marine habitats. Reports ... -
Biotechnology of marine fungi
(Springer, 2012)Filamentous fungi are the most widely used eukaryotes in industrial and pharmaceutical applications. Their biotechnological uses include the production of enzymes, vitamins, polysaccharides, pigments, lipids and others. ... -
Tectonics of the Ninetyeast Ridge derived from spreading records in adjacent oceanic basins and age constraints of the ridge
(American Geophysical Union, 2012)Analysis of new and existing geophysical data for the Central Indian and Wharton Basins of the Indian Ocean were used to understand the formation and evolution of the Ninetyeast Ridge (NER), especially its relationship to ... -
Contribution of tropical cyclones to the air-sea CO2 flux: A global view
(American Geophysical Union, 2012)Previous case studies have illustrated the strong local influence of tropical cyclones (TCs) on CO sub(2) air-sea flux (F sub(CO2)), suggesting that they can significantly contribute to the global F sub(CO2). In this study, ... -
Monitoring the sedimentary carbon in an artificially disturbed deep-sea sedimentary environment
(Springer, 2012)An area of 0.6 km sup(2) in the manganese nodule field of the Central Indian Basin was physically disturbed and sediments discharged in the near bottom waters to simulate seabed mining and study its impact on benthic ... -
Mixed response in bacterial and biochemical variables to simulated sand mining in placer-rich beach sediments, Ratnagiri, West coast of India
(Springer, 2012)The influence of mechanical disturbance of sediment-akin to small scale mining on bacterial community and biochemical variables was investigated at Kalbadevi beach, Ratnagiri, a placer-rich beach ecosystem which is a ... -
Authigenic carbonates in the sediments of Goa offshore basin, western continental margin of India
(Current Science Association, 2012)Euhedral crystals (approx. 1 mm) of authigenic carbonates are identified in 5 m long sediment cores collected from the western continental margin of India in water depths between 2665 and 3070 m. Low-Mg calcite and aragonite ... -
Variations in nearshore waves along Karnataka, west coast of India
(Indian Academy of Sciences, 2012)Wind wave spectra were recorded simultaneously at three shallow (water depth 7–9 m) locations (Malpe, Honnavar and Karwar) along the 200 km stretch of the state of Karnataka in 2009 during 27 April–24 May (representing ... -
Phenyltins in Surface Sediments of the Visakhapatnam Harbour, India
(Springer, 2012)Twenty-two surface sediment samples were collected from Visakhapatnam harbour, east coast of India, and analysed for monophenyltin (MPT), diphenyltin (DPT), triphenyltin (TPT), total bacteria, and TPT tolerant bacteria. ...
