Source investigation of the tar balls deposited along the Gujarat coast, India, using chemical fingerprinting and transport modeling techniques
(American Chemical Society, 2014)Deposition of tar balls (TBs) along the south Gujarat coast, situated on the west coast of India (WCI), commonly occurs during the southwest monsoon season. Several offshore oil fields off the Mumbai-Gujarat coast, and ... -
Mass spectrometry for determination of bioactive compounds
(Elsevier, 2014)Mass spectrometry (MS) has emerged as an invaluable technique with a wide array of applications ranging from forensic, proteomic, metabolomic to clinical studies. With the development of different ionization techniques and ... -
Vibrational spectroscopy for structural characterization of bioactive compounds
(Elsevier, 2014)Vibrational spectroscopy is one of the widely used analytical technique that require short analysis time, less sample quantity, provide non destructive and situ analysis of biological samples. Infrared and Raman spectroscopies ... -
Kinetic speciation and bioavailability of copper and nickel in mangrove sediments
(Elsevier, 2014)An attempt was made to establish a mechanistic linkage between chemical speciation of copper and nickel, and their bioavailability in mangrove ecosystem. Kinetic speciation study was performed to determine the concentrations ... -
Chemistry and petrology of Fe-Ni beads from different types of cosmic spherules: Implication for precursors
(Elsevier, 2014)Fe–Ni beads are observed to occur in all three (Stony, Glass, Iron) types of cosmic spherules collected from deep sea sediments of the Indian Ocean. Fe–Ni beads in cosmic spherules can provide insights for understanding ... -
Observation on foreshore morphodynamics of microtidal sandy beaches
(Current Science Association, 2014)Foreshore morphology and morphodynamics were examined to identify stability of two microtidal sandy beaches, Kundapura and Padukare, along the Karnataka shoreline on the west coast of India during three annual cycles from ... -
The effect of organic carbon on fixed nitrogen loss in the eastern tropical South Pacific and Arabian Sea oxygen deficient zones
(Association for the Sciences of Limnology and Oceanography, 2014)The three major oxygen deficient zones (ODZs) of the world oceans (eastern tropical North and South Pacific (ETNP and ETSP, respectively), and Arabian Sea (AS) host the vast majority of pelagic fixed nitrogen (N) loss and ... -
Anti-proliferative and angio-suppressive effect of Stoechospermum marginatum (C. Agardh) Kutzing extract using various experimental models.
(Korean Nutrition Society and the Korean Society of Community Nutrition, 2014)Abundant consumption of seaweeds in the diet is epidemiologically linked to the reduction in risk of developing cancer. In larger cases, however, identification of particular seaweeds that are accountable for these effects ... -
Impact of 'Chitra' oil spill on tidal pool macrobenthic communities of a tropical rocky shore (Mumbai, India)
(Coastal and Estuarine Research Federation, 2014)A collision between the ships MSC Chitra and MV Khalijia 3 in the mouth region of Mumbai Harbour led to a leakage of around 800 t of fuel oil in August 2010, affecting the rocky intertidal region of Colaba. To evaluate the ... -
Sources and distribution of organic matter in thirty five tropical estuaries along the west coast of India-a preliminary assessment
(Elsevier, 2014)Studies characterizing the sources of organic matter (OM) to the west coast of India (WCI) and its continental shelf are limited. This study examined sedimentary OM in 35 estuaries along the WCI using molecular biomarkers ... -
Fungi living in diverse extreme habitats of the marine environment
(Mycological Society of India, 2014)The marine environment contains several habitats characterized by extreme living conditions. However, extremophilic marine fungi were neither well known, nor often studied. Many studies in recent years have shown that fungi ... -
Using remote sensing and gis techniques for detecting land cover changes of mangrove habitats in Goa, India
(Sana’a University, 2014)Ecologically Sensitive Marine Habitats (ESMH), including mangroves ecosystems, is of immense ecological and socioeconomic values. Goa, a tourist destination, has limited cover of such habitats and has been intensively ... -
Genetic divergence between Auxis thazard and A. rochei based on PCR-RFLP analysis of mtDNA D-loop region
(Central Fisheries Research Institute (CFRI) Trabzon, 2014)Tunas of genus Auxis are commercially and ecologically important fish of family Scombridae. There is currently no information concerning the genetic divergence between A. thazard and A. rochei. Therefore, a study was ... -
Near shore waves, long-shore currents and sediment transport along micro-tidal beaches, central west coast of India
(Elsevier, 2014)Coastlines are undergoing constant geomorphologic changes with respect to the incident wave climate. Based on waves measured at 9 m water depth, simulation of near shore wave transformation is done using REFDIF-1 numerical ... -
Multifractal detrended fluctuation analysis to characterize phase couplings in seahorse (Hippocampus kuda) feeding clicks.
(Acoustical Society of America, 2014)Nonlinear phenomena in animal vocalizations fundamentally includes known features, namely, frequency jump, subharmonics, biphonation, and deterministic chaos. In the present study, the multifractal detrended fluctuation ... -
Beach dynamics and oscillations of shoreline position in recent years at Miramar Beach, Goa, India: a study from a GPR survey.
(Springer, 2014)Consideration of human influences is crucial to understanding the coastal sediment supply and associated shoreline responses prior to undertaking coastal hazard management studies. Observation of the widening of some ... -
What drives nearshore sediment transport controls on the depletion of beach placers at Manavalakurichi, Southwest Coast of India?.
