Latest Science Highlights

  • Predominantly Indus derived sandy sediments widespread in the Thar Desert have significant dust contributions to the Himalayan frontal glaciers (Bhattacharyya et al., 2024)
  • Isotopic evidence of autochthonous OM seqestering anthropogenic heavy metals in modern lacustrine sediments (Ahmad et al., 2024)
  • Decadal growth of atmospheric Zn, Pb, and Cd pollution in Central India emerged in the early-1980s yet shows no phasing-out trends (Ahmad & Singh, 2023)
  • Roles of anthropogenic land-use and wetland conservation practices in the rapid alteration of autochthonous and allochthonous sediment supplies to the Upper Lake, Bhopal (Ahmad et al., 2022)
  • Latitudinal migration of inter-tropical convergence zone and moisture contents in tropical/subtropical precipitation drivers controlled the Kashmir Valley hydroclimate during the late Holocene (Lone et al., 2022)
  • No lateral seawater intrusion but a widespread marine influence on the groundwater salinity in the coastal Gujarat alluvial plain, India (Qasim et al., 2022)
  • A recent decline (2004–2017) in estuarine heavy metal pollution of the Gulf of Cambay, India (Qasim et al., 2022)

Ongoing Research

  • Biogeochemical exploration of trace metals in Indian estuaries and nearby seas
  • Evaluation of Pb isotope fractionation during the soil formation and sedimentary processes
  • Human perturbations in the Upper Lake watershed, Bhopal
  • Impacts of seawater intrusion and aquifer-water interaction on groundwater solutes in coastal areas
