Changes in metal contamination levels in estuarine sediments around India – An assessment
(Elsevier, 2014)This review is the first attempt to comprehend the changes in metal contamination levels in surface estuarine sediments with changing time around India. Contamination factor, geoaccumulation index, pollution load index, ... -
Stochastic formalism-based seafloor feature discrimination using multifractality of time-dependent acoustic backscatter
(European Geosciences Union, 2014)Dual-frequency echo-envelope data acquired using the normal-incidence single-beam echosounder system (SBES) have been examined to study its scale invariant properties. The scaling and multifractality of the SBES echo ... -
Tropical cyclones in two atmospheric (re)analyses and their response in two oceanic reanalyses
(Elsevier, 2014)In this paper, we first evaluate the ability of the European Centre for Medium Range Forecast operational analysis and the ERA-Interim reanalysis to capture the surface wind signature of tropical cyclones (TCs). In those ... -
Next Generation Biofilm Inhibitors for Pseudomonas aeruginosa: Synthesis and Rational Design Approaches
(Bentham Science, 2014)The bacterial biofilms and the emergence of multiple drug resistance have become a major threat for current medical treatment of nosocomial infections. It has been estimated that about 65-80% of microbial infections in the ... -
Arene ruthenium(II) azido complexes incorporating N intersection O chelate ligands: Synthesis, spectral studies and 1,3-dipolar-cycloaddition to a coordinated azide in ruthenium(II) compounds
(Elsevier, 2014)The arene ruthenium(II) azido compounds [{(p-cymene)Ru(N^O)N<sub>3</sub>}] have been prepared by the reaction of [{(p-cymene)Ru(mewN<sub>3</sub>)Cl}<sub>2</sub>] with the corresponding ligands. The ruthenium azido compounds ... -
Air-Sea Interactions of Natural Long-Lived Greenhouse Gases (CO2, N2O, CH4) in a Changing Climate
(Springer, 2014)Understanding and quantifying ocean–atmosphere exchanges of the long-lived greenhouse gases carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) are important for understanding the global biogeochemical cycles of ... -
Amino acid biogeochemistry and bacterial contribution to sediment organic matter along the western margin of the Bay of Bengal
(Elsevier, 2014)Six sediment cores collected from various water depths and sampling locations along the western margin of the Bay of Bengal (BOB) were investigated for the total hydrolysable amino acids (THAA) and d-amino acids (d-AA) to ... -
Boron/calcium ratios in Globigerinoides ruber from the Arabian Sea: Implications for controls on boron incorporation
(Elsevier, 2014)Culture and downcore studies have been used to argue that B/Ca ratios in planktic foraminifera are correlated with seawater pH and may record seawater borate/bicarbonate ratios, although other factors may also control B/Ca. ... -
Equatorial Indian Ocean productivity during the last 33 kyr and possible linkage to Westerly Jet variability
(Elsevier, 2014)The top 1 m radiocarbon dated section of a 5.6 m long sediment core retrieved from the Equatorial Indian Ocean is studied for productivity changes in response to climate variability that have taken place during the last ... -
Shallow water wave spectral characteristics along the eastern Arabian Sea
(Springer, 2014)The spectral characteristics of shallow water waves were studied at two locations along the eastern Arabian Sea during 2011. Wave spectra were single-peaked from June to October and predominantly double-peaked during the ... -
Sub-hourly changes in biogeochemical properties in surface waters of Zuari estuary, Goa
(Springer, 2014)Processes in natural waters are highly variable in time and space. Although changes are expected in short-time scales, how short one could get to measure reliably is subjective to sampling strategies and methodologies. ... -
Contrasting phytoplankton community structure and associated light absorption characteristics of the western Bay of Bengal
(Springer, 2014)Absorption spectra, particulate pigments, and hydrochemical constituents were measured in the western Bay of Bengal (BoB) during July-August 2010 when influence of river discharge is at peak. Chromophoric dissolved organic ... -
Pore-water chemistry of sediment cores off Mahanadi Basin, Bay of Bengal: Possible link to deep seated methane hydrate deposit
(Elsevier, 2014)Organoclastic degradation and anaerobic oxidation of methane (AOM) are known to influence sulfate, methane and bicarbonate concentrations of sediment pore-waters. In this work we have analyzed the pore-fluid composition ... -
Full-length cloning and phylogenetic analyses of translationally controlled tumour protein and ferritin genes from the Indian white prawn, Fenneropenaeus indicus (H. Milne Edwards)
(John Wiley, 2014)Elucidation, through molecular analyses, of bacterial afflictions in commercially important aquaculture- reared shrimps is pivotal for the prevention and/or control of disease outbreaks. In this study, we examined the ... -
Characterization of Yellow Seahorse Hippocampus kuda feeding click sound signals in a laboratory environment: an application of probability density function and power spectral density analyses
(Taylor and Francis, 2014)Do the sounds generated by different-sized fish of different sexes differ from each other in temporal, spectral or intensity patterns? Such differences would enable the development of passive acoustic techniques to locate ... -
Culturable bacterial phylogeny from a shallow water hydrothermal vent of Espalamaca (Faial, Azores) reveals a variety of novel taxa
(Current Science Association, 2014)Phylogenetic diversity of the 16S rRNA gene associ-ated with the domain bacteria was examined at the level of operational taxonomic units (OTUs) using the rarefaction analysis from a newly identified shallow water hydrothermal ... -
Identification of optimum outfall location for desalination plant in the coastal waters off Tuticorin, India
(University of Tehran, 2014)Behaviour of the dilution characteristics of the coastal waters off Tuticorin is presented in the background of setting up of a desalination plant. Simulations of dispersion and spreading of the proposed discharges has ... -
Mobilization of manganese by basalt associated Mn(II)-oxidizing bacteria from the Indian Ridge System
(Elsevier, 2014)The Indian Ridge System basalt bearing Mn-oxide coatings had todorokite as the major and birnesite as the minor mineral. We posit that microorganisms associated with these basalts participate in the oxidation of Mn and ... -
Multifractal approach for seafloor characterization
(IEEE, 2014)This letter involves multifractal characterization of pockmark seepage associated seafloor along the central part of the western continental margin of India. Six representative blocks of backscatter and bathymetry coregistered ... -
