The origin and tectonic setting of precambrian greywacke of Ribandar-Chimbel, Goa, India: Petrological and geochemical evidence
(Geological Society of China, 2016)The Precambrian greywacke of Ribandar-Chimbel belonging to the Sanvordem Formation of the Goa Group, India, has been studied for petrography and analyzed for major trace elements. The greywacke is characterized by angular ... -
Effect of submarine canyons on tsunami heights, currents and run-up off the southeast coast of India
(Current Science Association, 2016)Tsunami numerical model studies are mostly focused on inundation and run-up onto the coast. Fewer studies have been aimed at investigating role of submarine canyons on the tsunami heights, currents and run-up. The influence ... -
Ancient Indians (Harappan settlement) were aware of tsunami/storm protection measures: A new interpretation of thick walls at Dholavira, Gujarat, India
(Current Science Association, 2016)Dholavira, an archaeological site of Harappan times in Gujarat, had ‘city fortification’ as a unique aspect of its town planning. The thickness of the main city wall is alarming3, 9, 10. The probable cause of such massive ... -
Distribution and fractionation of rare earth elements and Yttrium in suspended and bottom sediments of the Kali estuary, western India
(Springer, 2017)Concentrations of rare earth elements (REE) and yttrium (Y), and major metals (Al, Fe and Mn) were measured in suspended particulate matter (SPM) and bottom sediments of the Kali estuary, western India, for their distribution ... -
First evidence of denitrification vis-a-vis monsoon in the Arabian Sea since late Miocene
(Nature Publishing Group, 2017)In the Arabian Sea, South Asian monsoon (SAM)-induced high surface water productivity coupled with poor ventilation of intermediate water results in strong denitrification within the oxygen minimum zone (OMZ). Despite the ... -
Biodegradation of crude oil using marine Bacillus species from Vadinar coast, Gujarat, India
(Current Science Association, 2017)The marine environment is open to large sources of toxic organic waste in the form of accidental oil spills. Therefore, it is important to study microbial degradation processes that help reduce the damage caused to the ... -
Controls on evolution of gas-hydrate system in the Krishna-Godavari basin, offshore India
(American Geophysical Union Publications, 2017)Abstract In this study, we integrate environmental magnetic, sedimentological, and geochemical records of sediment core of Hole NGHP-01-10D overlying methane hydrate deposits to decipher the controls on the evolution of ... -
Observed salinity changes in the Alappuzha mud bank, southwest coast of India and its implication to hypothesis of mudbank formation
(Elsevier, 2017)Alappuzha mud bank draws special attention among the twenty-mud bank locations reported along the Kerala coast by its remoteness from riverine sources. Among several hypotheses proposed for the formation of mud bank, the ... -
Copepod grazing and their impact on phytoplankton standing stock and production in a tropical coastal water during the different seasons
(Springer, 2017)The grazing rate of copepods on the total and size-fractionated phytoplankton biomass in a coastal environment (off Kochi, southwest coast of India) were measured during pre-monsoon (PRM), peak southwest monsoon (PKSWM), ... -
Muddy waters
(ICSF, 2017)As mud banks along the southwest coast of India dwindle, several concerns and societal implications have been articulated regarding this unique oceanographic phenomenon -
Biotransformation and detoxification of xylidine orange dye using immobilized cells of marine-derived Lysinibacillus sphaericus D3
(MPDI, 2017)Lysinibacillus sphaericus D3 cell-immobilized beads in natural gel sodium alginate decolorized the xylidine orange dye 1-(dimethylphenylazo)-2-naphthol-6-sulfonic acid sodium salt in the laboratory. Optimal conditions were ... -
Nature of suspended particles in hydrothermal plume at 3°40'N Carlsberg ridge: A comparison with deep oceanic suspended matter
(Current Science Association, 2017)Suspended matter from hydrothermal plume at 3◦40'N Carlsberg Ridge was studied for microtexture and geochemistry. Characteristics of these plume particles were compared with deep-oceanic particulates from different ... -
Description of two new apseudomorphan Tanaidacea (Crustacea: Malacostraca: Peracarida) from the Kochi Backwaters, India
(Station Biologique de Roscoff, 2017)Two new species of apseudomorphan tanaidaceans, Pagurapseudopsis kochindica and Ctenapseudes indiana are described as new to science. Specimens used in this study are based on an extensive sampling (79 locations) in the ... -
Astrobiological implications of dim light phototrophy in deep-sea red clays
(Elsevier, 2017)Red clays of Central Indian Basin (CIB) under influence of trace of Rodriguez Triple Junction exhibited chemoautotrophy, low temperature hydrothermal alterations and photoautotrophic potential. Seamount flank TVBC-08, ... -
Autotrophic potential in mesophilic heterotrophic bacterial isolates from Sino-Pacific marine sediments
(Springer and Chinese Society of Oceanography, 2017)Microbial carbon fixation is a paramount process in the ocean especially below the photic zone both in water and sedimentary ecosystems. Autotrophic microbes that fix carbon dioxide are renowned. However, the question ... -
An integrated approach to study the biomarker responses in marine gastropod Nerita chamaeleon environmentally exposed to polycyclic aromatic hydrocarbons
(ISJ, 2017)Ecological risk assessment using multiple biomarkers produce a large amount of data that is hard to interpret and the result are often contradictory. In this context, Integrated Biomarker Response (IBR) index was used to ... -
Spatial distribution of dinoflagellates from the tropical coastal waters of the South Andaman, India: Implications for coastal pollution monitoring
(Elsevier, 2017)Dinoflagellate community structure from two semi-enclosed areas along the South Andaman region, India, was investigated to assess the anthropogenic impact on coastal water quality. At the densely inhabited Port Blair Bay, ... -
Observations of long-period waves in the nearshore waters of central west coast of India during the fall inter-monsoon period
