Influence of river discharge on the distribution and flux of methane in the coastal Bay of Bengal
(Elsevier, 2017)Rivers are known to be strong sources of methane (CH4) to the atmosphere and their discharges may also enhance its flux from the coastal ocean. In order to examine this, CH4 fluxes to the atmosphere were examined along the ... -
Recombinant Xylanase from Bacillus tequilensis BT21: Biochemical Characterization and Its Application in Production of Xylobiose from Agricultural Residues
(University of Zagreb, Croatia, 2017)Bacterial strain Bacillus tequilensis BT21 isolated from marine sediments was found to produce extracellular xylanase. The xynBT21 gene encoding xylanase enzyme was cloned and expressed in Escherichia coli. The gene encoded ... -
Estimation of diatom and dinoflagellate cell volumes from surface waters of the Northern Indian Ocean
(Elsevier, 2017)Phytoplankton samples collected from the Northern Indian Ocean (Bay of Bengal, northern Arabian Sea, and Dona Paula Bay Goa, west coast of India), were utilized to quantify changes in cell size, cell volume and carbon per ... -
Observations of the sub-inertial, near-surface East India Coastal Current
(Elsevier, 2017)We present surface current measurements made using two pairs of HF (high-frequency) radars deployed on the east coast of India. The radar data, used in conjunction with data from acoustic Doppler current profiler (ADCP) ... -
Biochemical composition of the alligator pipefish, Syngnathoides biaculeatus (Bloch, 1785)
(Science Press, 2017)Considering the economic importance in traditional Chinese medicine (TCM) and lack of baseline information, we evaluated the proximate composition, fatty acid and amino acid profiles, trace element content and C:N ratio ... -
Investigating the impacts of treated effluent discharge on coastal water health (Visakhapatnam, SW coast of Bay of Bengal, India)
(Springer, 2017)The present study investigated the impacts of treated effluent discharge on physicochemical and biological properties of coastal waters from three pharmaceuticals situated along the coast of Visakhapatnam (SW Bay of Bengal). ... -
Disease symptoms and growth performance of grey mullet infected with Myroides odoratimimus
(Wiley, 2017)M. odoratimimus behave as low-grade opportunistic pathogen was isolated from the gut of Mugil cephalus, which infers M. cephalus, a vector for the pathogen entry to human patients. The isolated M. odoratimimus showed ... -
Observation of dominance of swells over wind seas in the coastal waters of the Gulf of Mannar, India
(Copernicus Publications for EGU, 2017)Wind seas typically dominate over swell seas in coastal gulfs. Waves measured at a location having a water depth of 12?m in the near-shore waters of the Gulf of Mannar during a 1-year period (1 May 2015 to 30 April 2016) ... -
Investigations of the spatial and temporal variations of Sr and Nd isotopes in sediments from two Indian Rivers: Implications to source identification
(Wiley, 2017)Radiogenic isotopes of Sr and Nd provide crucial information on chemical and physical erosion processes, therefore used as tracers for fingerprinting the sources of fluvial sediments. Moreover, elemental geochemistry, ... -
Source analysis of radiocesium in river waters using road dust tracers
(Pergamon, 2017)Following the Fukushima Dai-ichi Nuclear Power Station accident, regional road dust, heavily contaminated with radiocesium, now represents a potential source of radiocesium pollution in river water. To promote effective ... -
Reply to the comment by M. Genge and M. Van Ginneken on paper entitled "Unmelted cosmic metal particles from the Indian Ocean".
(Wiley, 2018)This is an extended reply to the comments made on the paper entitled "Unmelted cosmic metal particles from the Indian Ocean" by M. Genge and M. Van Ginneken. The authors states that the hypotheses throughout the comment ... -
Use of geospatial techniques in maritime archaeology with reference to the Tamil Nadu coast
(Current Science Association, IAS, 2017)Geospatial analysis of shoreline changes at a particu-lar place includes topographic sheets, satellite image-ries and field data. The remains of maritime activities along the Indian coast have been traced dating back to ... -
Biological pretreatment and bioconversion of agricultural wastes, using ligninolytic and cellulolytic fungal consortia
(Taylor & Francis, 2017)Agricultural wastes have attractive potential as alternate energy sources. However, a major bottleneck is to identify eco-friendly treatment methodologies to utilize them. The large diversity of unexplored, novel, and ... -
Observed tidal currents on the continental shelf off the east coast of India
(Elsevier, 2017)In the present study, we analysed 9-month long data from Acoustic Doppler Current Profilers (ADCP) deployed on the shelf off the east coast of India to study the characteristics of tidal currents in the region. The ADCPs ... -
Unmelted cosmic metal particles in the Indian Ocean
(Wiley, 2017)Fe?Ni metal is a common constituent of most meteorites and is an indicator of the thermal history of the respective meteorites, it is a diagnostic tool to distinguish between groups/subgroups of meteorites. In spite of ... -
Selective Disparity of Ordinary Chondritic Precursors in Micrometeorite Flux
(IOP Publishing, 2018)All known extraterrestrial dust (micrometeoroids) entering the Earth's atmosphere is anticipated to have a significant contribution from ordinary chondritic precursors, as seen in meteorites, but this is an apparent ... -
Bioremediation potential of hydrocarbon-utilizing fungi from select marine niches of India
(Springer, 2018)Ten fungal isolates with an ability to degrade crude oil were isolated from select marine substrates, such as mangrove sediments, Arabian Sea sediments, and tarballs. Out of the ten isolates, six belonged to Aspergillus, ... -
Polycyclic Aromatic Hydrocarbons (PAHs) and Hopanes in Plastic Resin Pellets as Markers of Oil Pollution via International Pellet Watch Monitoring
