How biological (fish) noise affects the performance of shallow water passive array system
(NIOT, Chennai, 2015)Passive acoustic data off Grand Island, Goa were acquired using a single wideband hydrophone system deployed at the water depth of ~20.5 m during the month of April, 2014. The 4- elements hydrophone array with an aperture ... -
Fine scale analyses of a coralline bank mapped using multi-beam backscatter data
(NIOT, Chennai, 2015)In this work, we have developed a classification technique to characterize the seafloor of the Gaveshani (coralline) bank area using multi-beam backscatter data. Softcomputational techniques like the artificial neural ... -
Marine Robots : Applications in Marine Archaeology
(Agam Kala Prakashan, New Delhi, 2015)This article explains how underwater robots have the potential to become companions (buddies) to divers, effectively assisting them by carrying tools and instrumentation and taking high resolution images under the commands ... -
Post-capture immune gene expression studies in the deep-sea hydrothermal vent mussel Bathymodiolus azoricus acclimatized to atmospheric pressure
(Elsevier, 2015)Deep-sea hydrothermal vents are extreme habitats that are distributed worldwide in association with volcanic and tectonic events, resulting thus in the establishment of particular environmental conditions, in which high ... -
Comparative biogeochemistry–ecosystem–human interactions on dynamic continental margins..
(Elsevier, 2015)The oceans' continental margins face strong and rapid change, forced by a combination of direct human activity, anthropogenic CO2-induced climate change, and natural variability. Stimulated by discussions in Goa, India at ... -
Preface: Biogeochemistry–ecosystem interaction on changing continental margins in the Anthropocene
(Elsevier, 2015)This special issue presents case studies of different continental marginswith different settings and problems. The domains examined cover awide spectrumof continental margin environments, fromwatersheds, estuaries and ... -
Applications of Remote Sensing and Geographic Information System (GIS) in Archaeology
(Agam Kala Prakashan. New Delhi, 2015)The advancement of remote sensing technology and the analysing capability of Geographical Information System (GIS) can very well be used in the science of Archaeology. Though these subjects look apart, they can be studied ... -
Marine Archaeological Explorations at Kulasekharapattinarn and Manapad Region, Tamil Nadu
(Agam Kala Prakashan, New Delhi, 2015)Maritime activities along the Tamil Nadu date back to the second half of the 1st millennia BC and a large number of port towns developed all along the Tamil Nadu coast. The coastal and offshore explorations have yielded a ... -
Possible Location of Gaspar Dias Fort in Relation to the Present River Bank
(Agam Kala Prakashan, New Delhi, 2015)Historical records reveal the existence of a military fort within the Mandovi estuary. The structure was built in 1598 opposite the Reis Magos fort, extended in the adjoining area of the present traffic circle of Miramar, ... -
Early Historic Shipwreck Archaeology of the Indian Subcontinent Region
(Agam Kala Prakashan, New Delhi, 2015)Shipwreck archaeology in South Asian region is rather recent when one compares with the rest of the world and shipwrecks of the Bronze Age are unknown so far. There is also limited information on the shipwrecks of the early ... -
Climate Induced Vegetational Evolution: Palynological and Thecamoebian Study from Coastal Archaeological Sites, Saurashtra
(Agam Kala Prakashan, New Delhi, 2015)Coastal archaeological sites serve as potential archive of past climate-culture and vegetation relationship responding to relative sea level changes. Most of the Harappan dwellers along the coastal region largely depended ... -
Dinoflagellate cyst distribution in recent sediments along the south-east coast of India
(Elsevier, 2013)The spatial variation in the dinoflagellate cyst assemblage from the south-east coast of India is presented along with a comparison of the cyst abundance from other regions of the world Samples from 8 stations revealed the ... -
Chemical characterization of meltwater from East Rathong glacier vis-a-vis Western Himalayan glaciers
(Springer, 2015)Ice and meltwater samples from Rathong glacier and its pro-glacial stream Rathong chu, were collected during late winter season. Samples were analyzed to study the chemical composition , weathering, and geochemical processes ... -
Particle swarm optimization based support vector machine for damage level prediction of non-reshaped berm breakwater
(Elsevier, 2015)The damage analysis of coastal structure is very much essential for better and safe design of the structure. In the past, several researchers have carried out physical model studies on non-reshaped berm breakwaters, but ... -
