Microplastic Pollution in a Tropical River–Mangrove System of the Brahmani River in Bhitarkanika Wildlife Sanctuary, Odisha (India)NARA Subscribed
Microplastics (MPs), recognised as emerging contaminants, are increasingly prevalent in riverine ecosystems due to escalating anthropogenic activities. River deltas, which typically serve as ecologically rich and pristine habitats, are now under threat from solid and liquid waste inputs, particularly in rivers flowing through urban and agricultural landscapes. This research investigates MP contamination in sediments of the Bra...
This study investigates the occurrence and ecological risks of microplastics (MPs) and trace elements in coastal agricultural soils from Karnataka, southern India. Surface and subsurface soils from mulched (watermelon) and unmulched (rice) fields were analyzed for MP abundance, morphology, polymer composition, and trace elements. Microplastics were identified using Attenuated Total Reflectance–Fourier Transform Infrared Spectr...
A 45-year climatological study of arctic stratospheric polar vortex dynamics and morphology using ERA5 data (1979–2023)NARA Subscribed
The Arctic Stratospheric Polar Vortex (SPV) is known for its high interannual variability, with major Sudden Stratospheric Warmings (SSWs) occurring approximately every second year and with three Exceptionally Strong Vortex (ESV) events in the past decades, which are associated with springtime ozone depletion. Understanding the dynamical and morphological properties of the SPV is crucial for predicting these extreme events, an...
This study investigates spatial variations in soil quality across five distinct land-use types—forest, roadside, agricultural, industrial, and residential—in the Manipal region of southern India. Ten surface soil samples from each land-use category were analysed for physico-chemical properties, geochemical composition, and environmental magnetic parameters to evaluate soil degradation and identify potential pollution sources....
Microplastic (MP) contamination in terrestrial ecosystems—particularly in agricultural soils—remains an underexplored environmental concern in India, an agriculture-driven economy. This study assessed MP contamination in paddy fields across 15 sites in Udupi (Karnataka) and Goa, with soil samples collected from the surface and at three subsurface depths (10, 20, and 30 cm). MPs were extracted using density separation, identifi...
