What will I learn?

The Professional Science Masters (PSM) degree is a non-thesis, professional practice degree designed to allow students to advance their scientific knowledge while simultaneously developing or enhancing their abilities to apply scientific knowledge in a variety of professional settings, including but not limited to government or non-governmental organizations (NGOs) and private industry. This two-year program includes graduate-level coursework and an approved internship.

Program of Study

The PSM in Marine Sciences requires a minimum of 30 semester credit hours, including 5 credit hours in an internship (details below).

  • A minimum of 15 course credit hours must be completed from List #1 below – six of these credits must come from a set of core courses. Up to six of the 15 credits may be 400-level courses. The student’s advisor and PSM program coordinator may approve substitute courses for those in List #1, if (1) the course is highly relevant to the student’s career goals, and (2) the student’s background in marine sciences is deemed otherwise sufficient for a Master’s degree in this field. Relevant non-marine science course areas include but are not limited to anthropology, communications, biology and ecology, business administration, conservation biology and wildlife ecology, climate science, engineering, mathematics and statistics, psychology, public policy, resource economics, and sociology.
  • A minimum of 9 course credit hours of professional skills coursework is required. Students must also take one credit of the marine sciences graduate seminar, SMS 691. Finally, a minimum of five credits of an approved internship is required for completion of this program.
  • The internship (5 credits) is an important part of the PSM degree and must make a meaningful contribution to the individual’s professional development. The purpose of an internship is to immerse the student in an area of professional practice.
