General Opportunities in Field and Laboratory Based Studies (Graduate or Undergraduate)
My position does not permit sole supervision of graduate student theses, but I co-supervise or serve on graduate student theses committees, particularly those involving aspects of GIS, GPS, structural geology, tectonics and petrology/mineralogy. I have supervised several undergraduate student honors thesis, both lab- and field-based, and look forward to continuing to do so.

Aerogeophysical SystemsAerogeophysical Systems
UTIG has developed, maintained, and operated a suite of aerogeophysical instrumentation since the early 1990s with continual improvements since inception. The suite was installed aboard a Dehavilland DHC-6 ("Twin Otter") up to 2005 and aboard a Basler BT-67 (a version of DC-3T -- a Douglas DC-3 refitted with turboprop engines) since 2008. The current instruments are: High Capability Radar Sounder (HiCARS); Multibeam, Scanning Photon Counting Lidar; Cesium Vapor Magnetometer; Gravimeter; Dual-frequency, carrier-phase Global Navigation Satellite Systems (GNSS); Laser Altimeter; Two GPS-aided Inertial Measurement Units; Three-Axis Fluxgate Magnetometer; System Control, Data Acquisition, and Real-time QC and Monitoring functions.

Digital Morphology LibraryDigital Morphology Library
The Digital Morphology library (www.digimorph.org) is a National Science Foundation-funded initiative offering 2D and 3D visualizations of the internal and external structure of living and extinct vertebrates, and a growing number of non-vertebrates. Images are generated using the world's first high-resolution X-ray CT scanner in an academic science department, in the CT lab at the Jackson School.

Optec Laser Scanners (ILRIS)Optec Laser Scanners (ILRIS)
The Optec ILRIS Laser Scanners are part of the BEG RCRL/JSG consortium. They are state-of-the-art ground-based terrestrial laser scanning/mapping devices, that, when coupled with the Innovmetric Polyworks software, allows high-resolution mapping of earth-surface features,with accuracies of a few cm. These tools are part of the aresenal of tools that the RCRL uses to generate digital 3D earth models for carbonate reservoir analogs.

Paleomagnetic LabPaleomagnetic Lab
There are several aspects to our laboratory that make it different from others. One is our automatic handler system created at California Institute of Technology and adapted for our needs. Scientists and students can keep up with changes to our system by keeping in touch with the other 6 similar systems in the world and RAPID Consortium at http://rapid.gps.caltech.edu/. It also includes a cryogenic magnetometer and portable magnetic susceptibility meter (TerraPlus KT-10 Plus).

UT Sediment Transport and Earth-surface Processes (STEP) BasinUT 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 LibraryWalter 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.

Research Groups


Jack Holt's Research Group
Our research group is comprised of graduate students, undergraduates, technical staff and visiting students all focused on understanding both the current state of Mars ice and processes governing the distribution, history, and role of ice in Mars climate evolution. Our primary tool is orbital radar sounding, a technique that is relatively new for Mars, and for planetary exploration in general. Two radar sounders, MARSIS and SHARAD, are currently in orbit at Mars. Due to Dr. Holt's role as a Co-Investigator on SHARAD, we are very busy with the acquisition and analysis of new data. Building on UTIG's extensive experience in airborne radar sounding of ice on Earth, we have developed new analysis techniques specifically for SHARAD that give us unique capabilities and put us at the forefront of this exciting field.
