Influence of upwelling induced near shore hypoxia on the Alappuzha mud banks, South West Coast of India
(Elsevier, 2017)The results of the first time-series measurements spanning 18-weeks (22 April to 20 September 2014) from a coastal environment (Alappuzha, southwest India), where two process of upwelling and mud banks are concurrent during ... -
Antioxidant responses in gills and digestive gland of oyster Crassostrea madrasensis (Preston) under lead exposure
(Elsevier, 2017)Crassostrea are ecologically and economically important bivalves and provide a good livelihood for coastal regions of many countries, including India. This study aims at evaluating the response of the antioxidant defense ... -
Concentrations of heavy metals in commercially important Oysters from Goa, Central-West coast of India
(Springer, 2016)The major beds of oyster along the central-west coast of India are exposed to different anthropogenic activities and are severely exploited for human consumption. In this viewpoint, tissues of oyster Crassostrea ... -
Lithology, monsoon and sea-surface current control on provenance, dispersal and deposition of sediments over the Andaman continental shelf
(Lausanne, Switzerland : Frontiers Media, 2016)Sediments deposited on the Northern and Eastern Andaman Shelf along with a few sediments from the Irrawaddy and the Salween Rivers are studied for their elemental, Sr and Nd concentrations and their isotope composition ... -
Upwelling intensity modulates N2O concentrations over the western Indian shelf
(American Geophysical Union Publications, 2016)Repeat measurements of dissolved nitrous oxide (N<sub>2</sub>O) along two transects of the western continental shelf of India in 2012 revealed high concentrations of 45±32 nM (off Kochi) and 73±63 nM (off Mangalore) during ... -
Pseudofaults and associated seamounts in the conjugate Arabian and Eastern Somali basins, NW Indian Ocean- New constraints from high-resolution satellite-derived gravity data
(Elsevier, 2016)Marine gravity data derived from satellite altimeters are effective tools in mapping fine-scale tectonic features of the ocean basins such as pseudofaults, fracture zones and seamounts, particularly when the ocean basins ... -
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 ... -
