Do you want to study at-risk species and learn about marine conservation? Out of 57,155 vertebrates — mammals, birds, reptiles, amphibians, and fishes — the International Union for Conservation of Nature Red List of Threatened Species identified roughly 10,437 threatened species in 2021. Earning a master’s in marine biology and biological oceanography prepares graduates to work in academic research to promote marine conservation or find careers in business, consulting, policy, and teaching.
Master’s level biological science degreesprepare graduates for top-level marine biology and oceanography jobs or fast-track them to a Ph.D. program. After graduation, they can work as marine biologists, who in 2021 made a median annual salary of $64,650, according to the Bureau of Labor Statistics (BLS).
The average master’s level STEM degree takes two years. Some online degrees can be completed in 18 months since they have shortened semesters, which means they might cost less. According to the National Center for Education Statistics, the average public graduate school costs $12,410 a year. Private schools charge $26,597 a year. That said, the true cost of college can often cost more.
On this page, you’ll learn about the best online and on-campus master’s in marine biology and biological oceanography degrees and how you can go to college without going into debt.

Frequently Asked Questions About Marine Biology and Biological Oceanography Programs
Is a master’s in marine biology and biological oceanography worth it?
Yes, if you have a passion and dedication to marine ecology. A master’s in marine biology and biological oceanography can help you to secure research, teaching, and policy positions.
Students learn in labs, classrooms, and in the field. They study important topics such as the human impacts on the coastal environment, plankton ecology, and climatology. Many of the nation’s best master marine biology and biological oceanography programs operate out of schools situated in prime locations near the Pacific and Atlantic — and they may also offer international travel.
Colleges also offer online marine biology and biological oceanography degrees. Students can take remote courses that let students study from home, a convenience that benefits busy parents or working professionals.
What can I do with a master’s in marine biology and biological oceanography?
A master’s in marine biology and biological oceanography degree gives students the science background and research skills to work as marine biologists and researchers for state, national, and private environmental agencies. Graduates also apply their research skills and knowledge of marine biology to work in consulting, tech, business, and politics.
A master’s in marine biology and biological oceanography degree prepares students for the rigorous research and writing required in a Ph.D. program. Colleges such as William & Mary even offer accelerated Ph.D. pathways for master’s students who show promise in the field.
Are marine biology and biological oceanography graduates in demand?
While the BLS projects a slower than average employment growth for marine biologists, it projects the addition of roughly 1,700 positions each year from 2020-2030. About 40% of zoologists and wildlife biologists work in state government and 23% work for the federal government. They also work for consulting companies, colleges, and research and development.
Environmental scientists and specialists will see a projected employment growth of 8% in that decade, according to the BLS. During that time, employers should add about 9,400 openings each year.
Overall, life, physical and social science jobs should grow by 8%, with about 113,800 positions being added to the workforce in the next 10 years.
How much money can I make with a master’s in marine biology and biological oceanography?
What you make after earning a master’s in marine biology and biological oceanography degree depends on the job and your professional background. Graduates can become sustainability consultants, CEOs, program officers, professors, researchers, policy analysts, and marine biologists.
Professionals working in life, physical, and social sciences made a median annual salary of $72,740 in 2021, according to BLS. Marine biologists made the most working for the federal government, where they earned a median annual wage of $81,890. Wages often increase as marine biologists advance in their careers and contribute scientific research, with the top 10% making more than $103,900.
Environmental scientists and specialists earned a median annual salary of $76,530 in 2021, with the top 10% making more than $129,070.
What are the highest-paying jobs with a master’s in marine biology and biological oceanography?
Marine biologists can earn a median annual salary between $81,890-$61,780, depending on where they work — well above the national average salary of $55,630.
Graduates of master’s in marine biology and biological oceanography programs can also become research scientists who, according to PayScale, made an average of $84,290 a year as of June 2022. Environmental consultants earned an average annual salary of $60,180.
Another career possibility for marine biology graduates: college professors. Postsecondary teachers earned a median annual salary of $79,640 in 2021, according to the BLS. Marine science postsecondary teachers earned a median annual salary of $98,070.
