Yttrium and rare earth element contents in seamount cobalt crusts in the Indian Ocean
(Current Science Association, 2012)Cobalt-rich Fe-Mn crusts occur on almost all seamounts and plateaus of the world oceans. Fe-Mn crusts are formed through layer-by-layer accretion of colloidal precipitates from cold ambient seawater onto exposed seamount ... -
Imtechella halotolerans gen. nov., sp. nov., a member of the family Flavobacteriaceae isolated from estuarine water
(International Union of Microbiological Societies, 2012)A novel Gram-negative, rod-shaped, non-motile, non-sporulating bacterium, designated strain K1 sup(T), was isolated from an estuarine water sample collected from Kochi, Kerala, India. Colonies on marine agar were circular, ... -
Isolation and characterization of antibacterial compound from a mangrove-endophytic fungus, Penicillium chrysogenum MTCC 5108
(Association of Microbiologists of India, 2012)Microorganisms, especially endophytic fungi that reside in the tissue of living mangrove plants, seem to play a major role in meeting the general demand for new biologically active substances. During the course of screening ... -
Seismic characterization of hydrates in faulted, fine-grained sediments of Krishna-Godavari Basin: Full waveform inversion
(American Geophysical Union, 2012)In fine-grained, faulted sediments, both stratigraphic and fault-induced structural variations can simultaneously determine the gas hydrate distribution. Insights into hydrate distribution can be obtained from P wave ... -
Altimetric observations and model simulations of coastal Kelvin waves in the Bay of Bengal
(Taylor & Francis, 2012)Wavelet analyses of sea surface height (SSH) obtained from Simple Ocean Data Assimilation (SODA) reanalysis, satellite altimetry derived SSH anomalies during 1993–2006, and HYbrid Coordinate Ocean Model (HYCOM) simulations ... -
The 2005 volcano-tectonic earthquake swarm in the Andaman Sea: Triggered by the 2004 great Sumatra-Andaman earthquake
(American Geophysical Union, 2012)A 6 day duration earthquakes swarm occurred in the Andaman Sea, 31 days after the giant 2004 Sumatra-Andaman earthquake (Mw 9.2). The swarm occurred less than 100 km from the eastern edge of the 2004 earthquake rupture and ... -
Impact of tropical cyclones on the heat budget of the south Pacific Ocean
(American Meteorological Society, 2012)The integrated ocean response to tropical cyclones (TCs) in the South Pacific convergence zone through a complete ocean heat budget was investigated. The TC impact analysis is based on the comparison between two long-term ... -
Ganga-Brahmaputra river discharge from Jason-2 radar altimetry: An update to the long-term satellite-derived estimates of continental freshwater forcing flux into the Bay of Bengal
(American Geophysical Union, 2012)This paper discusses the use of Jason-2 radar altimeter measurements to estimate the Ganga-Brahmaputra surface freshwater flux into the Bay of Bengal for the period mid-2008 to December 2011. A previous estimate was generated ... -
Recent studies on wind seas and swells in the Indian Ocean
(IIT Bombay, 2012)Winds and waves measured at a few locations along the west coast of India were analysed to study the wave characteristics in the deep as well as near shore regions during different seasons. The potential generation of ... -
Modification of wind-wave model WAM and its verification against buoy data in the Indian Ocean
(IIT Bombay, 2012)An attempt is made to improve the accuracy of wave prediction in the Indian Ocean. For this purpose, two versions of the wave model WAM have been used: WAM (Cycle 4) and the new version of WAM, called NewWAM. The three ... -
A multi-sensor autonomous platform for fast ocean observation studies
(Indian National Centre for Ocean Information Services (INCOIS), 2012)A new platform Autonomous Vertical Profiler (AVP) has been developed at CSIR - National Institute of Oceanography in Goa, India that can rapidly and autonomously collect repetitive data to 200m water depth. It is equipped ... -
Seafloor roughness estimation employing bathymetric systems: An appraisal of the classification and characterization of high-frequency acoustic data
(American Institute of Physics, 2012)The study of the seafloor is important for living and non-living resource estimation along with the related processes identification. To understand the fine-scale seafloor processes, various methods such as application of ... -
Cecembia lonarensis gen. nov., sp. nov., a haloalkalitolerant bacterium of the family Cyclobacteriaceae, isolated from a haloalkaline lake and emended descriptions of the genera Indibacter, Nitritalea and Belliella
(Society for General Microbiology, 2012)A novel Gram-staining-negative, rod-shaped, non-motile bacterium, designated strain LW9T, was isolated from a water sample collected from Lonar Lake of Buldhana district, Maharashtra, India. Colonies and broth cultures ... -
Phytochemical profiles and antioxidant potential of four Arctic vascular plants from Svalbard
(Springer-Verlag, 2012)Environmental stress in the Arctic region leads to damage in plant membranes as a result of oxidation processes. To withstand these stress conditions, plants are expected to produce antioxidants that differ from phenolics. ... -
Antioxidant responses in Mesopodopsis zeylanica at varying salinity to detect mercury influence in culture ponds
(The Scientific and Technological Research Council of Turkey, 2012)Antioxidant responses in the estuarine mysid, Mesopodopsis zeylanica, were used to assess mercury (Hg) metal contamination in relation to salinity. Natural mysids acclimatized at 5 psu were subjected to laboratory exposures ... -
Enhanced biological production in the southeastern Arabian Sea during spring intermonsoon
