YCEI Postdoctoral Fellow, Jessica Barnes, will be leaving New Haven to take up a position at the University of South Carolina as an Assistant Professor in the Department of Geography and Environment and Sustainability Program.
Subpolar ocean gyres (large systems of rotating ocean currents) in the Southern Hemisphere are found poleward of the Antarctic Circumpolar Current near the Weddell and Ross Sea. They play a key role in the global energy and water budgets. These gyres are crucial for the transport of heat around the planet, as well as the distribution of nutrients and marine species. Thus, the subpolar gyres are important in the mixing and transformation of water masses.
Earth’s climate is characterized by persistent westerly jets (eastward flow) in the upper troposphere, located in the mid-latitudes of the Northern and Southern Hemisphere, which are associated locally with strong weather systems. The location of these jets is of paramount importance to human societies, as these are collocated with maximum in precipitation rates and surface winds in the extratropical regions.

Carbon sequestration, the removal of CO2 from combustion exhausts and its geological storage, is one of the major thrusts to reduce global warming. The only cost-effective, and commercially-available technology to remove CO2 from power plant flue gases for carbon sequestration relies on chemicals call amines to bind the CO2. Unfortunately, preliminary research has indicated that nitrogen oxides (NOx) in flue gases react with amines to form potent carcinogens called nitrosamines and nitramines.
Public discussions of climate change often focus on greenhouse gases and rising temperatures, but the most severe and immediate societal impacts of global warming are likely to be associated with changing hydrological conditions. Disruptions in water supply, extreme storms and record droughts may impact every aspect of rural and urban society: from agriculture and manufacturing to housing, energy and human health.
