Coastal circulation off Ratnagiri, west coast of India during monsoon seasons: a numerical model study.
(CSIR-NISCAIR, 2014)Present study is the coastal circulation modelling off Ratnagiri under the influence of winds and tides. A two-dimensional hydrodynamic model MIKE 21HD has been used to simulate tides and currents, and model results are ... -
Occurrence and distribution of multiple antibiotic-resistant bacteria of Enterobacteriaceae family in waters of Veraval coast, India
(University of Latvia, 2014)Current investigation was aimed to the assess occurrence and distribution of multiple antibiotic-resistant bacteria of the Enterobacteriaceae family in surface and bottom waters along the Veraval coast. Comparative prevalence ... -
Historical environmental pollution trend and ecological risk assessment of trace metals in marine sediments off Adyar estuary, Bay of Bengal, India.
(Springer, 2014)Geochemical, mineralogical and textural analyses were carried out in core sediments off Adyar estuary, Bay of Bengal, India to record the contamination trend from urban and industrial activities during the historical past. ... -
On the spatial structure and time evolution of shamal winds over the Arabian Sea – a case study through numerical modelling.
(Royal Meteorological Society, 2014)Shamal events are extra-tropical weather systems which occur in winter (cold and dry winds) as well as summer (hot and humid winds) with strong northwesterly or northerly winds blowing over the Arabian Peninsula. We have ... -
Sea breeze-induced wind sea growth in the central west coast of India.
(Elsevier, 2014)Fine resolution wind data is required in wave models to study the interaction between wind seas generated by coastal winds, and swells. In the present study, a mesoscale model, MM5, which is capable of reproducing fine ... -
Retrieval and Validation of Chlorophyll-a Concentrations in the Coastal Waters Off Yanam and Kakinada (Godavari) Basin Along East Coast of India.
(Springer, 2014)In this study chlorophyll measurements were made during March 2012 in the estuarine waters of Off Kakinada and Yanam coast, Bay of Bengal onboard a coastal vessel. In-situ water samples and optical data was collected at ... -
Characterization of phytoplankton pigments and functional community structure in the Gulf of Mannar and the Palk Bay using HPLC–CHEMTAX analysis.
(Elsevier, 2014)Phytoplankton marker pigments and their functional groups were identified for the first time in the Gulf of Mannar (GoM) and the Palk Bay (PB), located in the southeast coast of India using HPLC–CHEMTAX analytical techniques. ... -
Wave forecasting and monitoring during very severe cyclone Phailin in the Bay of Bengal.
(Current Science Association, 2014)Wave fields, both measured and forecast during the very severe cyclone Phailin, are discussed in this communication. Waves having maximum height of 13.54 m were recorded at Gopalpur, the landfall point of the cyclone. The ... -
Oxygen minimum zone of the open Arabian Sea: variability of oxygen and nitrite from daily to decadal timescales.
(European Geosciences Union, 2014)The oxygen minimum zone (OMZ) of the Arabian Sea is the thickest of the three oceanic OMZ. It is of global biogeochemical significance because of denitrification in the upper part leading to N<SUB>2</SUB> and N<SUB>2</SUB>O ... -
An early historic assemblage offshore of Godawaya, Sri Lanka: Evidence for early regional seafaring in South Asia.
(Springer, 2014)Investigations in 2010 by an international team of maritime archaeologists yielded a concentration of artefacts identified here by the authors as the remains of a shipwreck off the southern coastal village of Godawaya, Sri ... -
Determination of dynamic metal complexes and their diffusion coefficients in the presence of different humic substances by combining two analytical techniques.
(Taylor & Francis, 2014)The combined use of a competing ligand exchange (CLE) method and a diffusive gradient in thin films (DGT) technique in a quasi-labile system provides a better understanding of dynamic metal (Cu and Ni) complexes in the ... -
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 ... -
