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
(Springer, 2017)Oil pollution in the marine environment is an unavoidable problem due to chronic input from local sources, particularly in urban areas and oil spills. Oil pollution not only causes immediate physical damages to surrounding ... -
Spatial and temporal distribution of metals in suspended particulate matter of the Kali estuary, India
(Elsevier, 2017)Major (Al, Fe, Mn, Ti, Mg) and trace (Cu, Zn, Pb, Cr, Ni, Co, Zr, Rb, Sr, Ba, Li, Be, Sc, V, Ga, Nb, Mo, Sn, Sb, Cs, Hf, Ta, Bi, Th, U) elements and particulate organic carbon (POC) concentrations in surface suspended ... -
Influence of short-term hydrographic variations during the north-east monsoon on picophytoplankton community structure in the eastern Arabian Sea
(Elsevier, 2017)The eastern Arabian Sea over the continental margin is a dynamic region subjected to short-term variability in hydrography as a result of various physical forcing such as coastal advection and vertical mixing. In order to ... -
Tropical Cyclone Genesis Potential Index for Bay of Bengal During Peak Post-Monsoon (October-November) Season Including Atmosphere-Ocean Parameters
(Taylor & Francis, 2018)Several studies on tropical cyclone genesis potential index (GPI) mainly using atmospheric parameters (relative/absolute vorticity, relative humidity, vertical wind shear, potential instability, vertical velocity etc.) ... -
Global assessment of tropical cyclone intensity statistical-dynamical hindcasts
(Wiley, 2017)This paper assesses the characteristics of linear statistical models developed for tropical cyclone (TC) intensity prediction at global scale. To that end, multilinear regression models are developed separately for each ... -
Spatio-temporal variations in pathogenic bacteria in the surface sediments of the Zuari estuary, Goa, India
(Current Science Association, IAS, 2017)Estuaries are hotspots of anthropogenic activities. The deposition of pathogenic bacteria in the sediment and their re-suspension into the water column are influ-enced by riverine discharge and tides. The abundance of ... -
Wave energy dissipation due to mudbanks formed off southwest coast of India
(Elsevier, 2017)Mudbanks (MBs) are a unique natural phenomenon, and form along the southwest coast of India during the southwest monsoon. They are characterized by a calm-water region, bordered by a rough sea. In order to quantify the ... -
Intra-annual variations in phytoplankton biomass and its composition in the tropical estuary: Influence of river discharge
(Elsevier, 2018)To examine the influence of river discharge on phytoplankton composition, time-series observations were conducted at upper, middle and lower Godavari estuary during 2009. The salinity variations in the estuary were depended ... -
