East India Coastal Current induced eddies and their interaction with tropical storms over Bay of Bengal.
(IMarEST publishers, 2014)Eddies of about 10 to 500km in diameter, persisting for periods of days to months are commonly referred to as mesoscale eddies in oceanography. Energetic eddies are frequently found in the vicinity of faster flowing currents ... -
Hydrographic changes in the Agulhas Recirculation Region during the late Quaternary.
(European Geosciences Union, 2014)The strength of Southern Hemisphere westerlies, as well as the positions of the subtropical front (STF), Agulhas Current (AC) and Agulhas Return Current (ARC) control the hydrography of the southwestern Indian Ocean. ... -
Comparison of gridded multi-mission and along-track mono-mission satellite altimetry wave heights with in situ near-shore buoy data.
(Elsevier, 2014)The applicability of altimeter data for the coastal region is examined by comparing the gridded multi-mission and along-track mono-mission significant wave height (SWH) data with the in situ buoy measurements at four ... -
Distribution and abundance of mysid shrimps (Crustacea: Mysidacea) in the Northern Indian Ocean.
(Taylor & Francis, 2014)The distribution and abundance of mysids were studied based on materials collected from the upper 1000 m of the Northern Indian Ocean (Exclusive Economic Zone (EEZ) of India) during the period 2002–2006. A greater abundance ... -
An empirical algorithm to estimate spectral average cosine of underwater light field from remote sensing data in coastal oceanic waters.
(Association for the Sciences of Limnology and Oceanography, 2014)The underwater average cosine is an apparent optical property of water that describes the angular distribution of radiance at a given point in water. Here, we present a simple empirical algorithm to estimate spectral ... -
Growth of the Afanasy Nikitin seamount and its relationship with the 85 degree E Ridge, northeastern Indian Ocean.
(Indian Academy of Sciences, 2014)The Afanasy Nikitin seamount (ANS) is a major structural feature (400 km-long and 150 km-wide) in the Central Indian Basin, situated at the southern end of the so-called 85 degree E Ridge. Combined analyses of new multibeam ... -
Shallow geological environment of Krishna–Godavari offshore, eastern continental margin of India as inferred from the interpretation of high resolution sparker data.
(Indian Academy of Sciences, 2014)Krishna–Godavari offshore basin, a part of the eastern continental margin of India is a proven petroliferous basin. Recent drilling in this area in search of gas hydrates reveals that the upper 300 m thick Quaternary–Recent ... -
Distribution of clay minerals in marine sediments off Chennai, Bay of Bengal, India: Indicators of sediment sources and transport processes .
(Elsevier, 2014)Clay mineralogy, texture size and statistical analyses were carried out on surface sediments from the continental shelf of Chennai, Bay of Bengal, India. The purpose of this study is to characterize the clay mineral ... -
Bioaccumulation of heavy metals in commercially important marine fishes from Mumbai Harbor, India.
(Elsevier, 2014)Seventeen commercially important marine fish species were caught in Mumbai Harbor using a trawl net and evaluated using Atomic Absorption Spectroscopy and ICP-OES. It was found that certain species of fish contained lower ... -
Mercury speciation in coastal sediments from the central east coast of India by modified BCR method.
(Elsevier, 2014)This is the first study to describe distribution and speciation of Hg in coastal sediments from the central east coast of India. The concentrations of Hg in the studied sediments were found to be much lower than the Hg ... -
Extensive occurrence and genesis of authigenic carbonates from Krishna-Godavari offshore basin (Bay of Bengal): Possible influence of methane hydrates occurrences.
(Indian Geophysical Union, 2014)We report here the extensive occurrences of authigenic carbonate nodules/concretions from gas hydrate bearing sediments. Bulk mineralogical compositions by X-Ray diffractometry and EDS (Energy Dispersive Spectrum) analysis ... -
Chemosynthesis in deep-sea red-clay: Linking concepts to probable martian life
(Planex, 2014)Chemosynthetic microbial activity could share similarities between Martian and Earth systems. The present study examined the patterns of distribution of chemosynthetic bacteria in the deep-sea red clay sediments of CIB ... -
Genetic homogeneity in longtail tuna Thunnus tonggol (Bleeker, 1851) from the northwest coast of India inferred from direct sequencing analysis of the mitochondrial DNA D-loop region
(Taylor & Francis, 2014)Longtail tuna Thunnus tonggol is a neritic species of the family Scombridae, having a confined coastal distribution to tropical and temperate waters of the Indo-Pacific region In the present study, the population structure ... -
Assessment of water quality of a river-dominated estuary with hydrochemical parameters: A statistical approach.
(Springer, 2014)This study was aimed (1) to evaluate the water quality of Chalakudy river, the fifth longest (145.5 km) river of Kerala (South India), by assessing the general hydrochemical parameters like temperature, dissolved oxygen ... -
Influence of upwelling on distribution of chaetognath (zooplankton) in the oxygen deficient zone of the eastern Arabian Sea.
(Elsevier, 2014)he study addresses the coupled spatial scales in the physico-chemical variables and chaetognaths in the upwelling system of the eastern Arabian Sea during the 2005 summer monsoon. We studied the taxon between 0 and 1000 m ... -
