The School of Ocean Science and Engineering offers a Doctor of Philosophy in Marine Science with specialization in a wide range of marine science fields, including biological oceanography, geological oceanography, hydrographic science, marine chemistry, and physical oceanography. The Ph.D. program emphasizes excellence in research. Qualified students holding either a bachelor's or master's degree in a relevant field of science, mathematics, or computer science are encouraged to apply for admission to the Ph.D. program.
Students must meet the general requirements set forth in the Graduate Bulletin of The University of Southern Mississippi. The Ph.D. in marine science entails a minimum of fifty-four (54) semester hours of coursework beyond the bachelor's degree or master's degree.
In addition to the Admission Requirements and Procedures for all graduate programs as set forth in this Bulletin, regular admission to the Ph.D. program in marine science requires:
- Successful completion of the Graduate Record Examination (all sections) and a high grade point average for the last two years of undergraduate study as well as a 3.50 GPA on previous graduate study. Successful applicants have highly competitive scores and have a grade point average of 3.0 or above for undergraduate work and 3.5 on previous graduate study.
- Also required are three letters of recommendation from persons qualified to assess the applicant's readiness for graduate study.
- A letter of intent should also be addressed to the school director expressing personal academic and research goals.
- Students whose native language is not English must achieve a score of 84 or above on the internet-based TOEFL exam.
For students wishing to be considered for graduate assistantships for the academic year beginning in the fall semester, application materials should be received by the department no later than March 1.

Master of Science en route to Doctor of Philosophy in Marine Science
Ph.D. students may elect to earn an M.S. degree en route to the Ph.D. degree. To do so, students must complete all coursework requirements of the thesis-based marine science M.S. program, with the exception of MAR 698 (Thesis). Other electives, as determined by the student in agreement with their advisory committee, will be substituted for MAR 698. The student must also obtain approval of a Ph.D.-level research prospectus and pass a comprehensive examination. Successful completion of this non-thesis M.S. degree will be assessed based on a 'pass' or 'fail' assessment provided by each student's committee members and will also include review of the student's research progress. This option is only available to Ph.D. students wishing to earn the M.S. degree en route to the Ph.D.
