Selected Abstracts Images of Most Recent Research Susan L. Brantley Aqueous Geochemistry and Biogeochemistry at Penn State Susan L. Brantley, Professor of Geosciences, investigates chemical and physical processes associated with the circulation of aqueous fluids in shallow hydrogeologic settings and deep in the earth's crust.
Investigations incorporate field and laboratory work, and theoretical modelling of observations.
Of particular interest are questions concerning the measurement and prediction of the rates of natural processes, including chemical weathering and natural degassing. On this page are posted recent abstracts concerning feldspar dissolution and weathering kinetics and pictures of ongoing field work in Yellowstone National Park , where the rates of carbon dioxide degassing in the Park are being measured. The Water-rock Interaction Laboratory is one of many laboratories across the Penn State Campus which focusses on Environmental Chemistry and Geochemistry. The Center fosters undergraduate and graduate work in Environmental Chemistry and Geochemistry. BRIE is an NSF-funded inititative to fund up to 30 graduate and 30 undergraduate students to investigate the interface of microbiology and geochemistry at Penn State.
