High resolution climatic records of the past ~489 years from Central Asia as derived from benthic foraminiferal species, Asterorotalia trispinosa
(Elsevier, 2012)Many researchers have reported the occurrence of the species Asterorotalia trispinosa as a major constituent in foraminiferal assemblages from different regions, its ecological significance has never been studied. The ... -
Observational evidence from direct current measurements for propagation of remotely forced waves on the shelf off the west coast of India
(American Geophysical Union, 2012)We use data from six Acoustic Doppler Current Profiler (ADCP) moorings deployed during March–September 2008 on the continental shelf and slope off Bhatkal, Goa, and Jaigarh on the central west coast of India to present ... -
A study of meteorologically and seismically induced water level and water temperature oscillations in an estuary located on the west coast of India (Arabian Sea)
(The European Geosciences Union, 2012)The study examines the observed storm-generated sea-level oscillations (June 2007 and November 2009) during the Sumatra geophysical tsunami (September 2007), indicating similarities in the sea-level response in the Mandovi ... -
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, ... -
