Variation of biogenic sulphur compounds in the estuarine and coastal waters of Goa, West coast of India
(NIScPR-CSIR, India, 2022)Dimethylsulphide (DMS) originates predominantly from dimethylsulphoniopropionate (DMSP), a metabolite produced by phytoplankton.Through its contribution to the production of new aerosols and cloud condensation nuclei, a ... -
Geochemistry of uranium in the Ganga (Hooghly) River estuary, India: The role of processes in the water column and below the sediment-water interface
(Elsevier, 2022)In this study, we discuss the cycling of uranium (U) in the Ganga (Hooghly) River estuary through investigation of the composition of the water samples of six periods of contrasting water discharge, the bulk and exchangeable ... -
Spatio-temporal variations in culturable bacterial community associated with denitrification in the Arabian Sea oxygen minimum zone
(Taylor & Francis, 2022)The Arabian Sea (AS) oxygen minimum zone (OMZ) is a site of intense denitrification, contributing to 20% of the global oceanic denitrification, playing a significant role in the nitrogen cycle.In this study, the structure ... -
Response of benthic dinoflagellates Amphidinium carterae and Bysmatrum gregarium to salinity changes and prolonged darkness: Elucidation through laboratory experiments
(Springer, 2022)This study elucidates the responses of bloom-forming benthic dinoflagellates, Amphidinium carterae and Bysmatrum gregarium (formerly known as B.caponii) to salinity changes and prolonged darkness.Both dinoflagellates are ... -
On monitoring two major current systems of the north Indian Ocean using an array of deep-sea moorings
(Springer, 2022)The region between the southern tip of the Indian subcontinent and the equator links the Arabian Sea and the Bay of Bengal.A significant exchange of mass, heat and salt occurs in the region via two major current systems: ... -
Impact of atmospheric dry deposition of nutrients on phytoplankton pigment composition and primary production in the coastal Bay of Bengal
(Springer, 2022)Atmospheric deposition of pollutants decreases pH and increases the nutrient concentration in the surface water.To examine its impact on coastal phytoplankton composition and primary production, monthly atmospheric aerosol ... -
Bioactive Compounds from Polar Regions: An Account of Chemical Ecology and Biotechnological Applications
(Bentham Science Publishers Ltd., 2022)Organisms living in polar regions experience harsh environmental conditions.To cope and adapt to the extreme conditions, organisms produce specialized metabolites.Such metabolites exhibit various biological activities and ... -
Toxicity of Caulerpa scalpelliformis selected fractions with fatty acids on Porthesia scintillans
(Taylor & Francis, 2022)Porthesia scintillans, a serious pest threat to major crops.Here, we evaluated the toxicity of Caulerpa scalpelliformis fractions (CSF1, CSF2, and CSF3) against P.scintillans.Fraction CSF1 attracted P.scintillans larvae ... -
Antimicrobial Efficacy of Green Synthesized Nanosilver with Entrapped Cinnamaldehyde against Multi-Drug-Resistant Enteroaggregative Escherichia coli in Galleria mellonella
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)The global emergence of antimicrobial resistance (AMR) needs no emphasis.In this study, the in vitro stability, safety, and antimicrobial efficacy of nanosilver-entrapped cinnamaldehyde (AgC) against multi-drug-resistant ... -
Relics of 2.6-2.5~Ga oceanic crust from the ultramafic-mafic complex of Goa, western India: Magmatic response to a progressive subduction system
(Elsevier, 2022)Subduction initiation in the Early Earth and the onset of plate tectonics are topics of wide interest in understanding the formation and evolution of continents and supercontinents on our planet.Here we report results from ... -
Melt generation and trace element fractionation of intermediate arc magma from Andaman subduction zone
(Elsevier, 2022)The submarine volcanoes, located in the southern part of Andaman Sea, north eastern Indian Ocean, result from the subduction of the Indo-Australian Plate beneath the Southeast Asian Plate and represent one of the less ... -
Are Artificial Barrages Necessary to Prevent Saline Incursion? A Modelling Approach to Restore the Healthy Ecosystem of the Vembanad Lake
(Springer, 2022)The Thanneermukkom Bund was constructed to prevent salt water intrusion in the low lying areas of the Kuttanad region which increase the paddy cultivation twice in a year.Without it, paddy cultivation would be limited to ... -
Spatial Variability of Mud Bank along the Southwest Coast of India and Its Impacts
(Springer, 2022)The mud bank at Alleppey along the southwest coast of India is a persistent one that forms in June and dissipates by September during the southwest monsoon (SWM).A calm patch of turbid water with a thick fluid mud at the ... -
Dynamics of trace metals in sediments of a seasonally hypoxic coastal zone in the southeastern Arabian Sea
(Elsevier, 2022)This study examined the effect of water column hypoxia on the distribution and geochemical fractionation of trace metals in the seasonally hypoxic coastal environment in the southeastern Arabian Sea.Water and surface ... -
Dissolved and particulate iron redox speciation during the LOHAFEX fertilization experiment
