|Thermochronometric Paleohydrology (Graduate)|
The impact of fluid flow on the upper-crustal thermal structure is often difficult to evaluate. We have a suite of tunnel samples from the Alps (Mt. Blanc and new NEAT Gotthard base tunnel (55 km long and just recently completed) that cross either major fracture zones or infolded porous sediment, promoting tremendous amounts of water circulation and depressing the isotherms. For example in the Gotthard tunnel, the temperature in the tunnel is about 45C (!), but drops to about 15C at the location with the infolded seds and recovers to 45C north of the syncline. Similar things can be said for the Mt Blanc road tunnel, but there it's a fracture zone with plumbing linked to a glacial carapace some 2-3 km above the tunnel. I have detailed sample transects from these tunnels and this would or could be supplemented with surface samples. The goal would be do apatite and zircon He dating and to model the long-term thermal evolution of these isotherm deflections. This project and case study explores the implications of thermochronometric data coupled with numerical modeling and the long-term thermal structure and paleohydrology and its possible implications for paleoclimate (in the case of Mt Blanc).

It is 4 m wide, 8 m long, and 2 m deep. The tank has 5 observation windows, underwater lighting and an array of synced overhead cameras. The facility is designed to map underwater deposit surfaces in space through time and measure fluid dynamic and sediment transport properties of formative density flows.
|UT Sediment Transport and Earth-surface Processes (STEP) Basin|
The STEP Basin is an experimental flume designed to physically model morphodynamic and stratigraphic evolution of the fluviodeltaic system. It is 4 m wide, 5 m long, and 1.5 m tall. This facility is one of only three in the world with a computer-controlled basement motion, which can mimic 1) fore-hinge (passive margin), 2) back-hinge (foreland basin), and 3) lateral tilting subsidence patterns.
|Walter Geology Library|
The primary research collections of the library presently include more than 100,000 book and journal volumes and 46,000 geologic maps, among them the publications of the U.S. Geological Survey, most state geological surveys, and those of many foreign countries. Regional emphasis of the collection is on the Southwestern United States, Texas, and Mexico. The Institute and Bureau also have extensive libraries related to their specific research areas.
|Wind Tunnel/Flume Lab|
The Department of Geological Sciences maintains two wind tunnels for experiments in aeolian transport. One tunnel (0.5 m2 X 10 m) features a long transport section that ends in a slipface. The second tunnel features a rotating table (1 m in diameter) that can be used to simulate any range of wind directions.
|Center for Integrated Earth System Science|
The Center for Integrated Earth System Science (CIESS) is a cooperative effort between the Jackson School of Geosciences and the Cockrell School of Engineering. The center fosters collaborative study of Earth as a coupled system with focus on land, atmosphere, water, environment, and society.
|Center for Sustainable Water Resources|
The Center for Sustainable Water Resources conducts studies related to water quantity and quality aspects of water resources at local scales using field studies and regional scales using remote sensing and at annual to millennial timescales. Impacts of land use change and climate variability/change are important drivers considered in these studies. The results of these studies will have important implications for development of sustainable water resource programs in different regions.
|Land, Environment & Atmospheric Dynamics|
The LEAD group consists of graduate research assistants, postdoctoral fellows, research scientists and visiting scholars. We view the earth system in a holistic way, linking the atmosphere, ocean, biosphere, cryosphere, and solid earth as an integrated system. We use powerful methodologies such as satellite remote sensing and supercomputing simulations which are now profoundly changing research in earth system sciences. We place a strong emphasis on the societal impact of the research in earth system sciences.

|Center for Space Research|
The University of Texas at Austin, Center for Space Research was established in 1981 under the direction of Dr. Byron D. Tapley. The mission of the Center is to conduct research in orbit determination, space geodesy, the Earth and its environment, exploration of the solar system, as well as expanding the scientific applications of space systems data.
