The Marine Geosciences program at the University of Texas at Austin offers students a comprehensive education in the geology and geophysics of the Earth's oceans and seafloor. This interdisciplinary program combines principles of geology, geophysics, sedimentology, and oceanography to explore the processes shaping the marine environment, including plate tectonics, sediment transport, marine mineral resources, and hydrothermal systems. Students will gain a deep understanding of marine sediments, composition of the seafloor, and the techniques used to investigate underwater geological features through advanced geophysical methods such as seismic imaging, magnetic surveys, and acoustic methods. The curriculum emphasizes both theoretical knowledge and practical skills, providing hands-on experience in laboratory analysis, field studies, and data interpretation. Students have the opportunity to participate in research projects, including collecting core samples, mapping seafloor features, and analyzing geophysical datasets. The program is designed to prepare graduates for careers in academia, industry, government agencies, and environmental consulting, where expertise in marine geological processes and resource assessment is highly valuable. Additionally, the program fosters interdisciplinary collaboration with oceanographers, geophysicists, and environmental scientists to address critical issues related to marine resources, coastal hazards, and sustainable development. Equipped with state-of-the-art facilities and laboratories, students can engage in cutting-edge research both locally and internationally. Graduates from this program are well-positioned for roles in offshore exploration, marine resource management, environmental impact assessment, and scientific research. The program emphasizes fostering critical thinking, technical proficiency, and environmental stewardship, ensuring students are prepared to contribute meaningfully to understanding and preserving the Earth's marine environments.

On a general level, Marine Geosciences is a multi-disciplinary endeavor and students take a broad range of courses. This includes a Marine Geology & Geophysics Field Course to provide hands-on instruction for graduate and upper-level undergraduate students in collecting and processing Marine Geosciences data.

On average, Jackson School graduate students admitted with support receive some of the best overall packages in the country. In 2011-12, starting salaries for TAs and RAs were approximately $1,950 a month. Full fellowships were $36,000 for a 12-month period and are now eligible for the same UT Austin benefits package as any TA or RA. JSG support, in addition to being generous, is guaranteed (subject to requirements) and includes outstanding health benefits. Our students further benefit from living in Austin, a comparatively affordable U.S. city.

Standard offers of admission guarantee support for established durations, subject to satisfactory work performance and progress toward a graduate degree.

Durations of guaranteed institutional support:

  • Ph.D. Program: 10 semesters (fall and spring).

Guaranteed support takes the forms of fellowships, teaching assistantships (TAs), and graduate research assistantships (GRAs). Students pursuing the M.A. degree are not eligible for this support.

The Jackson School also provides:

  • Professional development support:
    • $3,000 for all Ph.D. students.
