Phosphorus accumulation associated with intense diagenetic metal-oxide cycling in sediments along the eastern continental margin of India
(Current Science Association, IAS, 2017)Sequential phosphorus extractions were carried out to understand phosphorus cycling and enrichment in surface sediments along the eastern continental margin of India. Phosphorus associated with authigenic (Paut) and biogenic ... -
Effects of salinity on cellular growth and exopolysaccharide production of freshwater Synechococcus strain CCAP1405
(Oxford University Press, 2018)The picocyanobacterium Synechococcus is ubiquitous in freshwater and high-saline marine ecosystems. The cellular response of freshwater Synechococcus to salinity variations is not well understood. Herein, we compare cellular ... -
ELISA detection of vitellogenin in the haemolymph of Penaeus monodon (Fabricius, 1798) (Caridea: Penaeidae): indirect indicator of female maturity
(Oxford University Press, 2017)Developing a non-lethal method for analysis of female reproductive maturity will be more accurate and less invasive than assessing maturity through gonad biopsy. Quantification of the expression levels of vitellogenin (Vg) ... -
Oblique strike-slip motion off the Southeastern Continental Margin of India: Implication for the separation of Sri Lanka from India
(Pergamon, 2018)The ocean floor in the Bay of Bengal has evolved after the breakup of India from Antarctica since the Early Cretaceous. Recent geophysical investigations including updated satellite derived gravity map postulated two phases ... -
Hindcast of breaking waves and its impact at an island sheltered coast, Karwar
(Springer, 2018)Variability in the characteristics of depth-induced wave breakers along a non-uniform coastal topography and its impact on the morpho-sedimentary processes is examined at the island sheltered wave-dominated micro-tidal ... -
Trace elements in ferromanganese nodules from the central indian ocean basin
(Taylor & Francis, 2017)Thirty-three bulk ferromanganese nodules from the sediment-water interface of siliceous sediment domain from the Central Indian Ocean Basin were analyzed for 50 elements including 6 new (Be, As, Se, Sn, Sb, and Bi) using ... -
Mid-troposphere transport of Middle-East dust over the Arabian Sea and its effect on rainwater composition and sensitive ecosystems over India
(Nature Publishing Group, 2017)The importance of mineral dust and aerosols in the transfer of bio-essential elements to terrestrial and marine ecosystems far removed from the source region is well known. Aerosol concentrations measured at the surface ... -
Phylogenetic characterization of culturable bacteria and fungi associated with tarballs from Betul beach, Goa, India
(Elsevier, 2018)Tarballs are semisolid blobs of crude oil, normally formed due to weathering of crude-oil in the sea after any kind of oil spills. Microorganisms are believed to thrive on hydrocarbon-rich tarballs and possibly assist in ... -
Differential impact of lytic viruses on prokaryotic morphopopulations in a tropical estuarine system (Cochin estuary, India)
(Public Library of Science, 2018)Our understanding on the importance of viral lysis in the functioning of tropical estuarine ecosystem is limited. This study examines viral infection of prokaryotes and subsequent lysis of cells belonging to different ... -
Biogeographic distribution of extant Coccolithophores in the Indian sector of the Southern Ocean
(Elsevier, 2017)Water samples from nine vertical profiles down to 110m water depth and 19 samples from the sea-surface were studied for coccolithophore abundance and distribution across oceanic frontal regions of the Indian sector of the ... -
Impact of river discharge on distribution of zooplankton biomass, community structure and food web dynamics in the Western coastal Bay of Bengal
(Elsevier, 2017)Observations were carried out along the western coastal Bay of Bengal, to examine the physical, chemical and biological parameters during the summer monsoon particularly when the rivers of India are in flood condition and ... -
Imhoffiella gen. nov., a marine phototrophic member of the family Chromatiaceae including the description of Imhoffiella purpurea sp. nov. and the reclassification of Thiorhodococcus bheemlicus Anil Kumar et al. 2007 as Imhoffiella bheemlica comb. nov.
(Microbiology Society, 2017)A coccoid-shaped phototrophic purple sulfur bacterium, strain AK35T, was isolated from a coastal surface water sample collected from Visakhapatnam, India. Cells were Gram-stain-negative, motile and purple, containing ... -
Bay of Bengal Exhibits Warming Trend During the Younger Dryas: Implications of AMOC
(Wiley, 2017)A sharp decline in temperature during the Younger Dryas (YD) preceding the current warmer Holocene is well documented in climate archives from the Northern Hemisphere high latitudes. Although the magnitude of YD cooling ... -
Influence of river discharge on the distribution and flux of methane in the coastal Bay of Bengal
(Elsevier, 2017)Rivers are known to be strong sources of methane (CH4) to the atmosphere and their discharges may also enhance its flux from the coastal ocean. In order to examine this, CH4 fluxes to the atmosphere were examined along the ... -
Recombinant Xylanase from Bacillus tequilensis BT21: Biochemical Characterization and Its Application in Production of Xylobiose from Agricultural Residues
(University of Zagreb, Croatia, 2017)Bacterial strain Bacillus tequilensis BT21 isolated from marine sediments was found to produce extracellular xylanase. The xynBT21 gene encoding xylanase enzyme was cloned and expressed in Escherichia coli. The gene encoded ... -
Estimation of diatom and dinoflagellate cell volumes from surface waters of the Northern Indian Ocean
(Elsevier, 2017)Phytoplankton samples collected from the Northern Indian Ocean (Bay of Bengal, northern Arabian Sea, and Dona Paula Bay Goa, west coast of India), were utilized to quantify changes in cell size, cell volume and carbon per ... -
Observations of the sub-inertial, near-surface East India Coastal Current
(Elsevier, 2017)We present surface current measurements made using two pairs of HF (high-frequency) radars deployed on the east coast of India. The radar data, used in conjunction with data from acoustic Doppler current profiler (ADCP) ... -
Biochemical composition of the alligator pipefish, Syngnathoides biaculeatus (Bloch, 1785)
