n-Alkanes in surficial sediments of Visakhapatnam harbour, east coast of India
(Indian Academy of Sciences, 2013)Surface sediments collected from 19 stations along Visakhapatnam harbour were analysed for organic carbon (OC), delta sup(13)C sub(oc), total lipids (TL), total hydrocarbon (THC), n-alkane concentration and composition. ... -
Fungal diversity from various marine habitats deduced through culture-independent studies
(Blackwell, 2013)Studies on the molecular diversity of the micro-eukaryotic community have shown that fungi occupy a central position in a large number of marine habitats. Environmental surveys using molecular tools have shown the presence ... -
Tetraselmis indica (Chlorodendrophyceae, Chlorophyta), a new species isolated from salt pans in Goa, India
(Taylor and Francis, 2013)A new species of Tetraselmis, T. indica Arora & Anil, was isolated from nanoplankton collected from salt pans in Goa (India) and is described based on morphological, ultrastructural, 18S rRNA gene sequence and genome size ... -
Yanai waves in the western equatorial Indian Ocean
(American Geophysical Union, 2013)Observations and models have shown the presence of intraseasonal fluctuations in 20-30-day and 10-20-day bands in the equatorial Indian Ocean west of 60 degrees E (WEIO). Their spatial and temporal structures characterize ... -
Geochemistry of the suspended sediment in the estuaries of the Mandovi and Zuari rivers, central west coast of India
(Springer, 2013)The geochemistry of the suspended particulate matter (SPM) collected during the monsoon was determined to identify the sources of SPM and to understand the physicochemical processes in the Mandovi and Zuari river estuaries. ... -
Deciphering detailed plate kinematics of the Indian Ocean and developing a unified model for East Gondwanaland reconstruction: An Indian-Australian-French initiative
(Department of Science and Technology , India, 2013)The Indian Ocean formed as a result of the fragmentation and dispersal of Gondwanaland since the Jurassic. The deep ocean basins in the Indian Ocean contain the imprints of this plate tectonic history, which is related ... -
Impact of atmospheric and physical forcings on biogeochemical cycling of dissolved oxygen and nutrients in the coastal Bay of Bengal
(Springer, 2013)Time-series observations were conducted off Visakhapatnam, central west coast of Bay of Bengal, from October 2007 to April 2009 to examine the influence of physical and atmospheric processes on water column nutrients ... -
Operational forecast of oil spill trajectory and assessment of impacts on intertidal macrobenthos in the Dahanu region, west coast of India
(Coastal Education and Reserch Foundation, 2013)A two-dimensional model has been developed and applied to the hypothetical spills of crude oil in the Dahanu area on the west coast of India. An attempt has also been made to quantify the intertidal macrobenthic biomass ... -
Marine actinobacteria showing phosphate-solubilizing efficiency in Chorao Island, Goa, India
(Springer, 2013)The occurrence and distribution of an actinobacteria group of bacteria capable of dissolving insoluble phosphates were investigated in this study in marine environments, especially in sediments of Chorao Island, Goa, India. ... -
Coupling between suboxic condition in sediments of the western Bay of Bengal and southwest monsoon intensification: A geochemical study
(Elsevier, 2013)Reconstruction of paleo-redox conditions in a radiocarbon (14C) dated sediment core (SK-218/1), covering the past 45 ka (thousand calendar years), collected from the western Bay of Bengal (Lat: 14 degrees 02′N; Long: 82 ... -
Effect of freshwater influx on phytoplankton in the Mandovi estuary (Goa, India) during monsoon season: Chemotaxonomy
(Scientific Research Publishing, 2013)The Mandovi estuary is a prominent water body that runs along the west coast of India. It forms an estuarine network with the adjacent Zuari estuary, connected via the Cumbharjua canal. The physico-chemical conditions seen ... -
Diseases and parasites in cultured yellow seahorse, Hippocampus kuda (Bleeker, 1852)
(Fishing Chimes, 2013)Yellow seahorses that occur in the sea, because of their commercial importance are now cultured. But they are prone to diseases and parasites. The problems encountered in rearing of juveniles, solutions and treatments are ... -
Influence of winds on temporally varying short and long period gravity waves in the near shore regions of the eastern Arabian Sea
(European Geosciences Union, 2013)Wave data collected off Ratnagiri, west coast of India, during 1 May 2010 to 30 April 2012 are used in this study. Seasonal and annual variations in wave data controlled by the local wind system such as sea breeze and land ... -
Preliminary observation on breeding three spotted seahorse, Hippocampus trimaculatus (Leach, 1814), solely fed with wild caught amphipods under ex-situ condition
(Indian Council of Agricultural Research, 2013)The reproductive efficiency of the wild caught brooding seahorse population was compared with captive bred F1 generation. Aquaculture has been proposed as a solution to address sustainable trade in seahorse, and for ... -
Dissolved methane in Indian freshwater reservoirs
(Springer, 2013)Emission of methane (CH4), a potent greenhouse gas, from tropical reservoirs is of interest because such reservoirs experience conducive conditions for CH4 production through anaerobic microbial activities. It has been ... -
Synthesis of (R)-norbgugaine and its potential as quorum sensing inhibitor against Pseudomonas aeruginosa
(Elsevier, 2013)(R)-Bgugaine is a natural pyrrolidine alkaloid from Arisarum vulgare, which shows antifungal and antibacterial activity. We have accomplished the simple synthesis of norbgugaine (demethylated form of natural bgugaine) ... -
Trophic efficiency of plankton food webs: Observations from the Gulf of Mannar and the Palk Bay, Southeast Coast of India
(Elsevier, 2013)This paper introduces the structure and trophic efficiency of plankton food webs in the Gulf of Mannar (GoM) and the Palk Bay (PB) - two least studied marine environments located between India and Sri Lanka. The study is ... -
Difficulties in obtaining representative samples for compliance with the Ballast Water Management Convention
(Elsevier, 2013)As implementation of the Ballast Water Convention draws nearer a major challenge is the development of protocols which accurately assess compliance with the D-2 Standard. Many factors affect the accuracy of assessment: ... -
