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.
