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
(Elsevier, 2017)The waves measured in the eastern Arabian Sea during the fall inter-monsoon period (October) are examined at 4 locations during 2010–2015. Multi-modal features have been observed in measured wave spectra due to independent ... -
Patterns of primary production in the Red Sea
(Elsevier, 2017)This paper presents data on various parameters of primary production (chlorophyll concentration, carbon uptake, nitrogen uptake, phytoplankton groups) measured in 4 cruises in the Saudi Arabian waters of the Red Sea between ... -
Oyster reef restoration in controlling coastal pollution around India: A viewpoint
(Elsevier, 2017)Coastal waters receive large amounts of nutrients and pollutants from different point and nonpoint sources through bays and estuaries. Excess supply of nutrients in coastal waters may have detrimental effects, leading to ... -
Suspended matter and fluid mud off Alleppey, southwest coast of India
(Elsevier, 2017)Time series measurements on suspended particulate matter (SPM) were made at one non-mud bank (M1) and two mud bank stations (M2 and M3) off Alleppey, south west coast of India. The mean SPM was low in surface (6.2 mg/l) ... -
Offshore sediments record the history of onshore iron ore mining in Goa State, India
(Elsevier, 2017)Environmental magnetic and geochemical analyses combined with 210Pb dating were carried out on a sediment core off Goa from Arabian Sea to reconstruct the sedimentation history of last three and a half centuries and to ... -
Dynamics of polycyclic aromatic hydrocarbons (PAHs) in surface sediments of Cochin estuary, India
(Elsevier, 2017)Polycyclic aromatic hydrocarbons (PAHs) showed significant seasonal dynamics in surface sediments of a tropical ecosystem (Cochin estuary, south west coast of India). Concentrations ranged from 304 to 5874 ngg<sup>-1</sup> ...
