The Jackson School has one of the country’s largest, most diverse, and most respected geophysics programs. Ranked No. 6 according to U.S. New & World Report, the geophysics program benefits from outstanding connections to industry and a strong grounding in basic research through the school’s major units, including the Institute for Geophysics, which employs 40 research scientists (and many JSG graduate students) working across the spectrum of geophysics research.
Overall, the Jackson School has about 250 graduate students in all disciplines, divided about equally between master of science and doctoral degree seekers. Both degrees involve original research in the form of a thesis or dissertation, and publication of results and presentation at professional society meetings is a goal for all graduate students.
Roughly 20 percent of the graduate student body is engaged in research that employs geophysical observations, and/or develops new geophysical techniques. The diverse graduate research opportunities in geophysics can be separated broadly into four major themes: field intensive studies; theoretical and numerical investigations; applied geophysics; and regional to global scale studies.
Examples include Antarctic expeditions with aero-geophysical surveys of major ice sheets; marine geophysical expeditions to understand tectonic and sedimentary processes over the continental margins and deep oceans; broad-band seismic experiments to illuminate the structure of the crust and upper mantle; airborne laser mapping of topography to understand terrestrial sedimentary processes; radar and electromagnetic investigations of the near-surface; and active source seismic experiments for near-surface and petroleum exploration studies. There are also development efforts for seismic sources and receivers, gravity, radar, and other field instrumentation.
Theoretical and numerical investigations
These include: solutions to inverse problems to estimate complex multi-parameter earth models from large data sets; development of numerical methods to simulate wave propagation and deformation in complex materials via finite element and finite difference methods; inference from and analysis of complex systems, such as Earth’s climate variations; and development of algorithms using parallel processing architectures.
Geophysical methods employing seismic and electromagnetic waves can be used to explore for resources, including petroleum, water, and others, and to estimate near surface physical properties for identification of hazards. Examples underway at UT include improved imaging of subsurface structures to support geological interpretation; estimation of subsurface physical properties from conventional and multi-component seismic data; and application of electromagnetic methods (radar and others) to estimate subsurface structure and physical properties.
Regional to global scale studies
UT geophysicists develop images of the interior of the earth using seismic waves; study earthquake sources and their distribution in time and space; interpret the deformation of the crust and the forces that cause them; and study Earth’s gravity and magnetic fields from surface and space-based observations.

|Ocean-Bottom Seismometer (OBS)|
An Ocean-Bottom Seismometer (OBS) is a seismometer that can be deployed on the seafloor for weeks or months, recording either earthquakes or man-made seismic signals. To withstand pressures at large depth (up to 5500 m) in the oceans, all electronics of this instrument are kept inside a glass sphere which can withstand such pressures. The sensors of all instruments (discussed below) include a 3-component accelerometer and a hydrophone, all designed for seismic data with a dominant frequency near 10 Hz. The seismic data are recorded on flash memory. Correct timing of the seismic recording is provided by an accurate clock, which also resides inside the sphere. After a seismic study on the seafloor is complete, the instrument is brought back to the sea surface using an acoustic release mechanism. UTIG has long been involved in marine seismology. The development of a UTIG OBS instrument program began in 1978.

|Portable High-Resolution Multichannel Seismic System (MCS)|
UTIG owns and maintains elements of a self-contained, portable, high resolution multichannel seismic (MCS) system that has been used over the past several years in salt- and fresh-water depths from ~4m to over 1km, on vessels from 10m to 35m in length. The 24-channel system is designed to be transported worldwide and to be installed on vessels of opportunity. Survey design, navigation, data acquisition, and near real-time MCS processing can be performed on non-dedicated laptops in the field. Deployment and recovery of gear is done by hand, requiring as few as 3 persons. The only constraints on the system are weight limits of the vessel and electrical requirements of the dedicated air compressors. For platforms with insufficient electrical capabilities, a fuel-powered generator or air compressor can be rented as a substitute.

The 272-TD towfish is lightweight enough so that it can be deployed by one person, which makes this system ideal for use from smaller boats or ones where an onboard handling system is not available. We utilize a Coda Geosurvey DA500 acquisition unit ( http://www.codaoctopus.com).
|Sub-Bottom Profiling Systems|
UTIG owns and maintains an integrated sonar system for use in conducting Compressed High Intensity Radar Pulse (CHIRP) subbottom profiling of the upper sediment layers of the ocean bottom or various fresh water systems.

Deployment and recovery of the towfish can be done by shipboard winches for shallower deployments or a larger UTIG-owned Electro-Hydraulic winch. Constraints on vessel size are dependent on shipboard winches capability of handling either the large (190kg SB-512i) or small (76 kg SB-216S) towfish. Power control, navigation, video display, data acquisition and data storage are all performed by one topside processing unit. The system can be powered by 18-36 VDC or 110/240 VAC (auto-ranging). The system is presently comprised of: 3200-XS topside computer processor, 4-transducer SB-512i towfish, 1-transducer SB-216s towfish, electro-hydraulic winch with 500 m of armored tow cable, 3 shallow water tow cables of 10, 25, and 50 m length, GPS navigation system.
