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
(Italian Association of Oceanography and Limnology, 2012)Hydrographic observations in the southeastern Arabian Sea (SEAS) have identified a warm (over 30 degrees C) and stratified water mass (stability more than 5x10 sup(-5) m sup(-1)) along the near shore area between 10 degrees ... -
Sequential interactions of silver-silica nanocomposite (Ag-SiO2 NC) with cell wall, metabolism and genetic stability of Pseudomonas aeruginosa, a multiple antibiotic-resistant bacterium
(Society for Applied Microbiology, 2013)The study was carried out to understand the effect of silver–silica nanocomposite (Ag-SiO sub(2)NC) on the cell wall integrity, metabolism and genetic stability of Pseudomonas aeruginosa, a multiple drug-resistant bacterium. ... -
Propagation of Atlantic Ocean swells in the north Indian Ocean: A case study
(European Geosciences Union, 2012)An analysis of altimeter significant wave height data of May 2007 revealed the occurrence of an extreme weather event off southern tip of South Africa in the Atlantic Ocean, and generation of a series of very high swells ... -
Nutraceutical properties of the marine macroalga Gayralia oxysperma
(Walter de Gruyter, 2012)We analyzed Gayralia oxysperma (Monostromataceae, Ulvales) from coastal waters in India for nutrients and biochemicals including nutritionally important fatty acids and active radical scavenging properties. This seaweed ... -
A simple method to minimize orientation effects in a profiling radiometer
(Taylor & Francis, 2012)Marine optical parameters required for ocean color satellite applications must be measured with high accuracy and errors within the permissible limits. These stringent requirements demand careful measurements of optical ... -
The bloom of the dinoflagellate (Noctiluca miliaris) in the North Eastern Arabian Sea: Ship and Satellite study
(Indian National Centre for Ocean Information Services (INCOIS), 2012)The bloom of Noctiluca miliaris (a dinoflagellate) which appears in the form of a green tide was studied from 2003-2011. This bloom covered a large area of the Arabian Sea from the west coast of India to the coast of Oman. ... -
Phytoplankton, Bacteria and Heterotrophic Nanoflagellate studies using ship and OCM-2 data along a coastal transect in the Arabian Sea
(Indian National Centre for Ocean Information Services (INCOIS), 2012)The coastal region of the central West coast of India is biologically productive and well known for its Mackerel and Sardine fishery. December is an active fishing month and fall in the post-monsoon period when coastal ... -
Distribution and ecology of the Trichodesmium spp. in the Arabian Sea: Ship and satellite studies
(Indian National Centre for Ocean Information Services (INCOIS), 2012)Trichodesmium is a filamentous cyanobacteria which forms dense blooms along the west coast of India in the Arabian Sea, the Lakshadweep Sea, the Andaman Sea and the Bay of Bengal. These are high biomass blooms which are ... -
An autonomous underwater vehicle "Maya", for monitoring coastal waters, estuaries, rivers and dams
(Indian National Centre for Ocean Information Services (INCOIS), 2012)This article demonstrates the use of Maya, Autonomous Underwater Vehicle (AUV) for monitoring coastal waters, estuaries, rivers and dams. Maya is a mono hull structure with detachable nose and tail cones. The nose cone is ... -
Recent studies on wind seas and swells in the Indian Ocean: A review
(SAGE Publications, 2013)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 swells ... -
Signatures of Indian Ocean dipole and El Nino-Southern Oscillation events in sea level variations in the Bay of Bengal
(American Geophysical Union, 2012)We investigate the impact of the Indian Ocean Dipole (IOD) and El Nino and the Southern Oscillation (ENSO) on sea level variations in the North Indian Ocean during 1957-2008. Using tide-gauge and altimeter data, we show ... -
Upper ocean variability in the Bay of Bengal during the tropical cyclones Nargis and Laila
(Elsevier, 2012)Upper ocean variability at different stages in the evolution of the tropical cyclones Nargis and Laila is evaluated over the Bay of Bengal (BoB) during May 2008 and May 2010 respectively. Nargis initially developed on 24 ... -
Some ecological aspects and potential threats to an intertidal gastropod, Umbonium vestiarium
(Triveni Enterprises, 2012)Kalbadevi Bay in Ratgnairi has been identified as potential site for placer mining along the west coast of India. Since, Umbonium vestiarium is a keystone species of the region; study on some ecological aspect was carried ... -
Petrological Characteristics and Genesis of the Central Indian Ocean Basin Basalts
(Geological Society of China, 2012)The Central Indian Ocean Basin (CIOB) basalts are plagioclase-rich, while olivine and pyroxene are very few. The analyses of 41 samples reveal high FeO sup(T) (approx. 10-18 wt percent) and TiO sub(2) (approx. 1.4-2.7 wt ... -
Linkage between seasonal insolation gradient in the tropical northern hemisphere and the sea surface salinity of the equatorial Indian Ocean during the last glacial period
(Geological Society of China, 2012)Paired stable oxygen isotope and Mg/Ca analyses in calcite tests of the mixed-layer-dwelling planktic foraminifer Globigerinoides ruber has been used to reconstruct equatorial Indian Ocean delta sup(18)O of seawater (delta ... -
Wealth of bioactive molecules from marine bacteria and their applications
(2012)By the term, "Bioactive molecules" we generally mean a range of compounds produced by living fauna and flora the effect of which tend to improve the status of man�s health, wealth and overall welfare These molecules could ... -
Distribution of intertidal phytobenthos of polluted and comparatively unpolluted regions along Mumbai
(University of Mumbai, 2012)The dynamics of microphytobenthos may be influenced by water pollution which can be through anthropogenic discharges including domestic waste water and industrial effluents. The pollutants in overlying water settle at the ... -
