Biogenesis of silver nanoparticles by marine bacteria Labrenzia sp. Mab 26 associated with Isochrysis galbana
(Current Science Association, IAS, 2020)
The metabolic or chemical nature of algal-bacterial interactions has opened up unexpected new ways for finding novel microbes with potential for several biotechnological applications. Silver nanoparticles (AgNps) possess ...
Influence of hypoxia on phosphorus cycling in Alappuzha mud banks, southwest coast of India
(2020)
The southwest coast of India is known to experience two concurrent processes during the southwest monsoon, namely coastal upwelling and mud banks at selected stretches such as that off Alappuzha. The mud bank sediments ...
Geochemical characterization of modern aeolian dust over the Northeastern Arabian Sea: Implication for dust transport in the Arabian Sea
(Elsevier, 2020)
The Arabian Sea, one of the most biologically productive oceanic regions, receive significant amount of nutrients through aeolian dust deposition which have potential to modulate surface water biogeochemical processes. ...
A rock magnetic perspective of gas hydrate occurrences in a high-energy depositional system in the Krishna-Godavari basin, Bay of Bengal
(Springer, 2020)
We conducted a detailed rock magnetic study complemented by sedimentological and mineralogical methods on a 177.2-m-long sediment core of Hole NGHP-01-14A to constrain the influence of high-energy depositional environment ...
Evaluation of Physical and Environmental Parameters of the Indian Sundarbans
(Springer , Singapore, 2020)
Deltas and associated coastlines are amongst the most rapidly changing landscape features, as these are subjected to physical, geological, biological and environmental threats. One of the largest deltas of the world, ...
Controls on greigite preservation in a gas hydrate system of the Krishna-Godavari basin, Bay of Bengal
(Springer Verlag, 2020)
Shallow sediments across large parts of Krishna-Godavari (K-G) basin offshore east central Indian contain abundant methane and gas hydrates. In this study, we carried out rock-magnetic and transmission electron microscope ...
Contrasting sulfidization in the turbidite and hemipelagic sediments of Bengal Fan
(Elsevier Ltd, 2020)
We report for the first time, contrasting sulfidization profiles in a sedimentary sequence comprising of clay-silt turbidites and hemipelagic dominated deposits in a channel-levee complex of the middle Bengal Fan. The ...
Inhibition of pathogenic Vibrio harveyi using calamenene, derived from the Indian gorgonian Subergorgia reticulata, and its synthetic analog
(Springer, 2020)
We report the synthesis and antimicrobial properties of a partially reduced dihydronathphthoquinone analogue of 2-methoxy, 5-acetoxy calamenene, extracted from Subergorgia reticulata. The growth of a pathogenic Vibrio ...
A revisit to the regulation of oxygen minimum zone in the Bay of Bengal
(Springer, 2020)
Occurrence of intense oxygen minimum zone (OMZ) is known in the Bay of Bengal (BoB), but it has been recently reported to have become more acute and is at its tipping point. Here, we show that the intensification of OMZ ...
Building Capacity and Resilience Against Diseases Transmitted via Water Under Climate Perturbations and Extreme Weather Stress
(Springer, Cham, 2020)
It is now generally accepted that climate variability and change, occurrences of extreme weather events, urbanisation and human pressures on the environment, and high mobility of human populations, all contribute to the ...
