The Jackson School has a long tradition of leadership in fundamental and applied studies of liquid and solid water. Our research addresses broad questions such as: How is water distributed and routed through the Earth’s surface and subsurface? What are the impacts of human activities on water resource availability and quality? How are different components of the Earth system including the biosphere linked, and what is the role of water in these linkages? How will the hydrosphere and cryosphere respond to climate change? Researchers use complementary high-performance computing, laboratory experiments and measurements, and intensive field work in order to address these questions.
Hydrogeologists and hydrologists in the Jackson School have expertise in aqueous and microbial geochemistry, isotope geochemistry, physical hydrogeology, surface water hydrology, vadose zone hydrology, ecohydrology, and hydrogeophysics. Glaciologists in the Jackson School have expertise in ice sheet evolution and dynamics, supra-, sub- and englacial hydraulic systems, and the geologic setting of ice sheets.
Jackson School researchers and students are currently investigating hydrogeologic and glacial processes around the world. Some of our studies are conducted in Greenland, Antarctica, the Pacific Islands, Australia, Mexico, Chile, Switzerland, Egypt, and China, in addition to studying the hydrogeology of Austin’s interesting karst landscape and other parts of Texas. Some researchers also study ice sheets and potential water flow paths on Mars and Europa.

|Center for Frontiers of Subsurface Energy Security|
CFSES is one of only two centers out of 46 EFRCs with focus on subsurface energy. Our goal is a scientific understanding of the physical, chemical, and biological subsurface processes from the very small scale to the very large scale so that we can predict the behavior of CO2 and other byproducts of the energy production that may need to be stored in the subsurface. At this aim, we need to integrate and expand our knowledge of subsurface phenomena across scientific disciplines using both experimental and modeling methodologies to better understand and quantify the behavior at conditions far from equilibrium. The unique aspect of our research is the approach of the uncertainty and of the complexity of the fluids in the geologic media from the molecular scale to the basin scale and their integration in computational tools to better predict the long term behavior of subsurface energy byproduct storage.
