Nutrient fluxes and adaptation to environmental dynamics by phytoplankton in the Gulf of Khambhat
(International Journal Of Current Research, 2011)Environmental dynamics with a view of understanding the nutrient fluxes and the factors regulating phytoplankton production, in waters off Bhavnagar, Gulf of Khambhat, were investigated during 1996-2007. The coastal waters ... -
Isolation and x-ray structure of deoxycholic acid from the sponge Ircinia sp.
(Natural Product Communications Inc., 2011)Ethyl acetate extract of the sponge Ircinia sp., collected by SCUBA divers off the coast of southern India, contained a cholest-based sterol of insignificant antimicrobial activity, with one carboxylic acid side chain (3 ... -
Rare earth elements in suspended and bottom sediments of the Mandovi estuary,central west coast of India: Influence of mining
(Elsevier, 2011)Rare earth elements (REEs) in the suspended particulate matter (SPM) of the Mandovi estuary indicated that the mean total-REEs and light REE to heavy REE ratios are lower than that of the average suspended sediment in World ... -
High-resolution mapping, modeling, and evolution of subsurface geomorphology using ground-penetrating radar techniques
(CRC Press, 2011)Ground Penetrating Radar (GPR) is widely used for mapping of subsurface. Features in civil, geological, geotechnical, and geo- environmental applications. Considering the available technologies to map surface features, GPR ... -
Bio-Prospecting of a Few Brown Seaweeds for Their Cytotoxic and Antioxidant Activities
(Hindawi Publishing, 2011)Methanolic extracts (MEs) of seven brown seaweeds occurring in the Indian coastal waters were screened for their cytotoxic and antioxidant properties following various assays. The methanolic extracts of seaweeds in the ... -
Sexual reproduction in Odontella regia (Schultze) Simonsen 1974 (Bacillariophyta)
(Current Science Association, 2011)The sequence of spermatogenesis and sperm cell count of Odontella regia (Schultze) Simonsen from Indian waters is reported. The sequence of events in the spermatogenesis producing 16 spermatogonia following four differentiating ... -
Tropical cyclones in the Bay of Bengal and extreme sea-level projections along the east coast of India in a future climate scenario
(Current Science Association, 2011)The simulations from the regional climate model, PRECIS (Providing REgional Climates for Impacts Studies), were analysed for the occurrence of tropical cyclones in the Bay of Bengal in a baseline scenario (1961–1990) and ... -
Interannual variability of the South Pacific Convergence Zone and implications for tropical cyclone genesis
(Springer, 2011)The interannual variability of the South Pacific Convergence Zone (SPCZ) and its influence on tropical cyclone (TC) genesis in the South Pacific are investigated using observations and ERA40 reanalysis over the 1979– 2002 ... -
Effect of January 15, 2010 annular solar eclipse on meteorological parameters over Goa, India
(Elsevier, 2011)Atmospheric perturbations due to the annular solar eclipse were monitored to understand its influence on the meteorological parameters from surface to the lower stratosphere. A strong inversion at 13 km and an abnormal ... -
Temporal derivative of Total Solar Irradiance and anomalous Indian summer monsoon: An empirical evidence for a Sun–climate connection
(Elsevier, 2011)Identifying the pattern of natural climate variability is of immense importance to delineate the effects of anthropogenic climate changes. Global and regional climates are suspected to vary, in unison or with delays, with ... -
Factors controlling January–April rainfall over southern India and Sri Lanka
(Springer, 2011)The factors controlling rainfall over southern India and Sri Lanka between January and April, i.e. outside of the southwest and northeast monsoons are explored. This period accounts for 20% of annual precipitation over Sri ... -
Antimicrobial Activity of Marine Sponge Clathria indica (Dendy, 1889)
(Pleiades Publishing, 2011)Sponges are sessile filter feeders that have developed efficient defense mechanisms against foreign invaders such as viruses, bacteria or eukaryotic organisms. Antimicrobial peptides are known as major components of the ... -
Recruitment of mud clam Polymesoda erosa (Solander, 1876) in a mangrove habitat of Chorao Island, Goa
(Universidade de São Paulo, Instituto Oceanográfico, 2011)Habitat-specific settlement success results either from active habitat selection or differential mortality after non-selective settlement. The mud clam Polymesoda erosa (Solander, 1876) is an ecologically and economically ... -
Maritime archaeological studies in India
(Oxford, 2011)India with more than 7000 km long coastline and about 5000 years old maritime history is dotted with several ancient ports. Marine archaeological research during last two and half decades has revealed a number of sites ... -
Ocean, Spreading Centre
(Springer, 2011)A midocean ridge, an underwater mountainous feature, extends for a length of about 65,000 km as a single continuous body in the global oceans. It is a window to the Earth's interior, through which magma is continuously ... -
A multi-method approach for the study of lanthanum speciation in coastal and estuarine sediments
(Elsevier, 2011)Two independent analytical methods (sequential extraction and kinetic extraction methods) were applied in order to understand the distribution and speciation of La in the coastal and estuarine sediments from the central ... -
Screening marine organisms for antimicrobial activity against clinical pathogens
(NISCAIR (CSIR), 2011)Bacterial resistance to existing antibiotics has led to the search for new therapeutic agents. With this aim, we have evaluated antimicrobial activity of extracts prepared from forty species of marine organisms belonging ... -
Objective mapping of observed sub-surface mesoscale cold core eddy in the Bay of Bengal by stochastic inverse technique with tomographically simulated travel times
(NISCAIR (CSIR), 2011)Present study consists the acoustic characteristics of a sub-surface cold core eddy observed (below the mixed layer between depths of 50 and 300m, with a diameter of about 200 km having temperature drop of 5 Degree Celsius ... -
Fine-scale responses of phytoplankton to freshwater influx in a tropical monsoonal estuary following the onset of southwest monsoon
(Indian Academy of Sciences, 2011)In May of 2007, a study was initiated by the National Institute of Oceanography (NIO), Goa, India, to investigate the influence of monsoonal rainfall on hydrographic conditions in the Mandovi River of India. The study was ... -
Reconstruction of Antarctic climate change using ice core proxy records from the coastal Dronning Maud Land, East Antarctica
(Geological Society of India, 2011)Antarctic ice core records have provided unprecedented information on past climatic changes and forcing factors on decadal to millennial timescales. The glaciochemical and stable isotope records of a shallow ice core from ...
