Variation of salinity in the Sundarbans estuarine system during the equinoctial spring tidal phase of march 2011
(Springer, 2021)The Sundarbans Estuarine System (SES), comprising the southernmost part of the Indian portion of the Ganga-Brahmaputra delta bordering the Bay of Bengal, is India's largest monsoonal, macro-tidal, delta-front estuarine ... -
Impact of physical processes on oxygen loss and production of hydrogen sulphide and methane in a tropical freshwater reservoir
(Springer, 2021)Carbon neutrality of tropical reservoirs is a big concern in recent years as some estimates project high methane emission from these reservoirs. While there are studies available on the impact of physical processes ... -
Fatty acids as indicators of sediment organic matter dynamics in a monsoon-influenced tropical estuary
(Elsevier, 2021)Sedimentary organic matter (OM) composition serves as a biomarker and helps in hindcast analysis of the events in the habitat. The present study was carried out on a monthly basis to evaluate the contribution of different ... -
Ocean impact on the intensification of cyclone Titli
(Springer, 2021)Tropical cyclones are the most devastating weather events which still needs to understand much due to the uniqueness in their paths and intensification locations. One such recent very severe cyclonic storm, Titli, is ... -
34S enrichment as a signature of thiosulfate oxidation in the " Proteobacteria "
(Oxford University Press (OUP), 2021)Kinetics of thiosulfate oxidation, product, and intermediate formation, and 34S fractionation, were studied for the members of Alphaproteobacteria Paracoccus sp. SMMA5 and Mesorhizobium thiogangeticum SJTT, the Betaproteobacteria ... -
Applications of SPOT-7 tri-stereo imagery in deriving the surface topography and mass changes of glaciers in Indian Himalaya
