Wave transformation and attenuation along the west coast of India: Measurements and numerical simulations
(World Scientific Publishing, 2013)Waves measured at a few locations along the west coast of India were analyzed to study modification and attenuation of wave energy in the nearshore regions. It has been found that the reduction in wave height is relatively ... -
Remote acoustic seafloor characterization using numerical model and statistical based stochastic multifractals
(Institute of Applied & Computational Mathematics, 2013)The spatial variability of sediment geoacoustic inversion parameters are estimated employing bathymetric systems such as multi-beam echo-sounder (MBES) and dualfrequency single-beam echo-sounder (SBES) operable at 95 kHz ... -
Maritime archaeology of Lakshadweep Islands, India
(Indian Archaeological Society, 2012)Lakshadweep Islands lie on the sea route between South Asia, Far East and African countries Boats and ships used the islands of Lakshadweep as a stopover to take on fresh water The Islands of Lakshadweep played a significant ... -
Waves in Gulf of Mannar and Palk Bay around Dhanushkodi, Tamil Nadu, India
(Current Science Association, 2013)Surface wave characteristics around Dhanushkodi are studied based on the measured data in the Gulf of Mannar and in the Palk Bay. Wave spectra are mainly double-peaked in the Gulf of Mannar and single-peaked in the Palk ... -
Sunlight-enhanced calcareous deposition on cathodic stainless steel in natural seawater
(Taylor and Francis, 2013)In replicate series of experiments in natural seawater, one in full darkness and the other in a 1:1 diurnal cycle with as little as 5 percent of natural solar illumination, sunlight promoted calcareous deposition on cathodic ... -
Model simulation of tide-induced currents in Gauthami-Godavari estuary
(Current Science Association, 2013)Predictive spatial distribution of flow field has been simulated from the time series data on currents and tides during dry season (11-19, February, 2009) in the Gauthami-Godavari Estuary utilizing TIDAL model. A 2D-Tidal ... -
Anatomical studies of timber and EPMA analysis of brass artefacts collected from steam engine shipwreck of Minicoy Island, Lakshadweep, India
(Current Science Association, 2013)From the early historical period onwards selection of timber became important for construction boats. The analysis of timber collected from shipwreck and wooden stock of iron anchor off Goa has been proven that Indian teak ... -
Wave power potential at a few shallow-water locations around Indian coast
(Current Science Association, 2013)Variations in nearshore wave power at four shallow water locations along the east and west coast of India are examined based on the measured wave data for one-year period. The study shows that along the west coast of India, ... -
Effects of iron availability on pigment signature and biogenic silica production in the coastal diatom Chaetoceros gracilis
(Taylor and Francis, 2013)The effects of iron availability on pigment signature and biogenic silica production were investigated for the first time in the coastal diatom Chaetoceros gracilis (isolated from the SW coast of the Bay of Bengal, India). ... -
Disruption of microbial biofilms by an extracellular protein isolated from epibiotic tropical marine strain of Bacillus licheniformis
(Public Library of Science, 2013)Marine epibiotic bacteria produce bioactive compounds effective against microbial biofilms. The study examines antibiofilm ability of a protein obtained from a tropical marine strain of Bacillus licheniformis D1. B. ... -
Identification of sources of tar balls deposited along the Goa coast, India, using fingerprinting techniques
(Elsevier, 2013)Deposition of tar balls along the coast of Goa, India is a common phenomenon during the southwest monsoon. Representative tar ball samples collected from various beaches of Goa and one Bombay High (BH) crude oil sample ... -
Geochemical variability of MORBs along slow to intermediate spreading Carlsberg-Central Indian Ridge, Indian Ocean
(Elsevier, 2013)ICP-MS trace element data from the Carlsberg Ridge MORBs from two different locations is presented. Using this data the intra-ridge geochemical variations of the Carlsberg Ridge - Central Indian Ridge MORBs is reassessed. ... -
Variation of paleo-productivity and terrigenous input in the eastern Arabian Sea during the past 100 ka
(Geological Society of India, 2013)A 4.1m long sediment core from the eastern Arabian Sea is studied using multiple geochemical proxies to understand the variation of productivity and terrigenous matter supply during the past 100 ka. The temporal variation ... -
Cytochrome Oxidase I (COI) sequence conservation and variation patterns in the yellowfin and longtail tunas
(Inderscience, 2013)Tunas are commercially important fishery worldwide. There are at least 13 species of tuna belonging to three genera, out of which genus Thunnus has maximum eight species. On the basis of their availability, they can be ... -
Benthic foraminifera
(Elsevier, 2013)Benthic foraminifera are protozoa, which evolved during Cambrian and at present are found living in all possible marine environments. Their single cell is enclosed in a microscopic calcareous or agglutinated shell called ... -
Sediment fluxes and the littoral drift along northeast Andhra Pradesh Coast, India: Estimation by remote sensing
(Springer, 2013)The littoral drift regime along the northeastern coast of India was investigated by analyzing coastal drift indicators and shoreline changes based on multitemporal satellite images. The study of offshore turbidity patterns ... -
