Astrobiology
What is the origin of life? Does it exist on other worlds? These two cosmological questions have captivated human curiosity for as long as we have had the capacity to wonder. These are questions that unify us across disciplines and schools at Georgia Tech and beyond. For most of our history, our conversations and explorations of these ideas have been imaginative, cultural, and philosophical.
Satellite Constraint Source specific Nitrogen Oxide Emissions and Isoprene Chemistry in the Southeast United States Evaluations and Implications for Background Ozone
Nitrogen oxides (NO x NO NO 2 originating from combustion, lightning and soil, are the main drivers of the tropospheric ozone formation and important precursors of secondary organic aerosols, with consequences for human health, climate and ecosystem Isoprene, the most important biogenic volatile organic compounds (globally, accounts for about half of the BVOC emissions 500 Tg yr 1 Its rapid oxidation in the presence of NO x is a main driver of atmospheric chemistry Detailed and accurate estimations of NO x emissions and a better understanding of isoprene chemis
Submesoscale Impacts on Tracer Transport in the Gulf of Mexico
Mesoscale and submesoscale dynamics and their role on the transport and mixing of ocean biogeochemical tracers have been investigated widely in recent literatures. In general, large circulations and mesoscale eddies control the absolute dispersion of tracers horizontally, while submesoscale motions affect horizontal mixing and, with their strong vertical velocities, control upwelling or subduction processes in the boundary layers, at the ocean surface and near its bottom.
