Fourteenth International Conference on Climate Change: Impacts & Responses

Abstract

Efforts have been made to study co-evolution of climate and marine life in the Arctic Sea through the correlation of ocean-atmosphere-cryosphere interactions with climate variability i.e. to evaluate correlation between the impacts of multiple stressors on the ocean and the associated risks of abrupt state shift, rising of sea level, melting of the glaciers, vis-à-vis climate variability. Also, to investigate correlation of arctic ocean atmospheric cryosphere (OAC) variability mechanism, sub-mesoscale dynamics and its impact on climate variability. Arctic Ocean regional variability of the sub-mesoscale dynamics includes examining high resolution satellite imageries with emphasis on the large scale kinematic and thermodynamic behaviour of selected mesoscale convective systems. Next, the oxidation process is employed in remediation of subsurface above-ground water treatment systems involving the regeneration of granular activated carbon (GAC) and to treat groundwater contaminants by making use of the chemical oxidant s viz. hydrogen peroxide, persulfate, permanganate and ozone causing chemical destruction of toxic organic chemicals. Also, to develop physicochemical and spectroscopic methods to characterize the in situ chemical speciation of the inorganic contaminants and develop technologies for remediation of water and environmental pollution by catalytic oxidants; as well as to investigate process fundamentals and assess contaminant transformation through chemical reaction kinetics.
