Airborne CO2 Observations in the Southern Great Plains

ESD’s Sebastien Biraud and others recently reported on 10 years of airborne measurements of atmospheric CO2 mole fraction from continuous and flask systems—collected between 2002 and 2012 over the ARM Climate Research Facility.

Reactive Transport Modeling to Track Contaminant Plumes at Savannah River

Nuclear weapons production during the Cold War has left groundwater contaminated at many sites in the United Sates, including the DOE Savannah River Site in South Carolina.

Genome-enabled Studies of Anaerobic, Nitrate-Dependent Iron Oxidation in the Chemolithoautotrophic Bacterium Thiobacillus denitrificans

In a study published recently in Frontiers in Microbiology, ESD’s Harry Beller and Peng Zhu (and others) report on efforts to identify genes associated with nitrate-dependent Fe(II) oxidation.

Microscopic Evidence for Liquid-Liquid Separation in CaCO3 Solutions

Former ESD geochemist Adam Wallace led a group of scientists in using molecular dynamics simulations to probe the structure, dynamics, and energetics of hydrated CaCO3 clusters, and lattice gas simulations, to explore the behavior of cluster populations before nucleation.
