Inter-annual variations in wave characteristics off Ratnagiri, Northeast Arabian Sea
(Elsevier, 2015)The wave data measured using the Datawell directional wave rider buoy at 13 m water depth off Ratnagiri during 2010 to 2013 is used to study the inter-annual variations in the wave characteristics. The percentage occurrence ... -
Magma production rate along the Ninetyeast Ridge and its relationship to Indian plate motion and Kerguelen hot spot activity
(American Geophysical Union, 2015)The Ninetyeast Ridge, a linear trace of the Kerguelen hot spot in the Indian Ocean, was emplaced on a rapidly drifting Indian plate. Magma production rates along the ridge track are computed using gravity-derived excess ... -
Plate tectonic reconstruction of India and Madagascar closing through the Mascarene Basin
(Ocean Society of India, 2015)The western continental margin of India was formed due to the rifting and drifting among India, Madagascar and Seychelles. Several researchers provided relative configuration of India and Madagascar in their pre-break-up ... -
Optical closure of apparent optical properties in coastal waters off Goa
(Indian Society of Remote Sensing, 2015)Inherent and apparent optical properties were measured for coastal waters off Goa, a site on the west coast of India using the in-situ measuring profiling optical instruments. The optical closure was obtained using the ... -
Distribution and abundance of benthic macroorganisms in and around Visakhapatnam Harbour on the east coast of India
(Marine Biological Association of the United Kingdom, 2015)Benthic communities form an important component of the marine food chain. Their occurrence also provides information on the health of the ecosystem. A study was carried out to understand the distribution and abundance of ... -
Field and laboratory investigations of budding in the tetillid sponge Cinachyrella cavernosa
(The American Microscopical Society, Inc., 2015)The budding process of the tetillid sponge Cinachyrella cavernosa was studied for one year in the low intertidal zone near Mhapan (15°55`27.48"N, 73°33`29.89"E), on the central west coast of India. The sponges showed the ... -
Diversity of thraustochytrid protists isolated from brown alga, Sargassum cinereum using 18S rDNA sequencing and their morphological response to heavy metals
(Marine Biological Association of the United Kingdom, 2015)Thraustochytrids, the exclusively marine organisms of kingdom Stramenopila and a source of essential fatty acids in the marine milieu, possess an osmoheterotrophic mode of nutrition and are therefore affected by type and ... -
Acoustic communication for Maya Autonomous Underwater Vehicle - performance evaluation of acoustic modem
(NIOT, Chennai, 2015)Autonomous underwater vehicles (AUV) traverse considerable distances underwater without any intervention. Very often the operations are in coastal waters with small depth, large horizontal distances, seabed obstacles, ... -
An Integrated Approach to Study Mud Banks of Alleppey Kerala using the Autonomous Vertical Profiler (AVP)
(NIOT, Chennai, 2015)Mud Banks of Kerala are areas of the sea adjoining the coast that have a special property of dampening the waves and creating clearly demarcated areas of calm water during the roughest monsoon conditions of the sea. It is ... -
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 ... -
