To become an oceanographer, you typically need at least a bachelor’s degree in oceanography, marine science, geology, physics, biology, or another related scientific field. A four-year degree can qualify you for some entry-level scientific, technical, field, and data-support positions.
However, many research oceanographers have a master’s degree or PhD. Graduate education becomes particularly important for scientists who want to specialize in a specific branch of oceanography, conduct independent research, or work in university and research-institute positions.
What Degree Do You Need to Be an Oceanographer?
| Degree | Typical career opportunities |
|---|---|
| Bachelor’s degree | Entry-level scientific, field, data, and technical positions |
| Master’s degree | Specialized research and more advanced scientific roles |
| PhD | Independent research, university research, and many academic positions |
Bachelor’s Degree
A bachelor’s degree is usually the starting point for an oceanography career and normally takes about four years of full-time study. Students build a foundation in mathematics, physical and natural sciences, data analysis, and their chosen ocean-related specialty.
The U.S. Bureau of Labor Statistics includes oceanographers within its discussion of geoscientists and states that geoscientists typically need a bachelor’s degree to enter the occupation. Some employers, however, prefer candidates with a master’s or doctoral degree for more advanced positions.
A bachelor’s degree may lead to work involving sample collection, laboratory support, oceanographic instruments, mapping, data processing, or assisting research teams. It does not necessarily qualify a graduate to immediately lead an independent scientific research program.
Master’s Degree
A master’s degree allows students to specialize more deeply in areas such as physical, chemical, biological, or geological oceanography. Graduate programs commonly involve advanced coursework, scientific data analysis, and a research project or thesis.
NOAA Fisheries notes that most research oceanographers have an advanced degree, such as a master’s degree or PhD, in oceanography, geology, marine resource management, or a related field.
A master’s degree may therefore be valuable for research-oriented positions where employers expect stronger technical expertise and experience designing or carrying out scientific studies.
PhD
A PhD is not required for every oceanographer, but it is common among scientists whose careers center on original research.
Doctoral students typically complete advanced coursework, conduct several years of specialized research, and prepare a dissertation based on original scientific work. A PhD is particularly useful for university research, academic careers, leading independent projects, and positions where scientists are expected to develop new research questions and methods.
The important distinction is that oceanography includes many types of work. A technical or applied position may be accessible with a bachelor’s or master’s degree, while an independent research career may require doctoral-level preparation.
What Should You Major in to Become an Oceanographer?
You do not necessarily need a degree with the exact title Oceanography. Oceanographers enter the field from several related STEM disciplines.
Common college majors include:
- Oceanography;
- Marine Science;
- Marine Biology;
- Geology;
- Physics;
- Chemistry;
- Environmental Science;
- Earth Science.
The best major depends largely on which part of the ocean you want to study.
Physical oceanography focuses on currents, waves, ocean circulation, temperature, and interactions between the ocean and atmosphere. Physics, mathematics, and oceanography provide particularly useful preparation.
Biological oceanography examines marine organisms, ecosystems, productivity, and relationships between ocean conditions and living systems. Biology, marine biology, ecology, and marine science are relevant majors.
Chemical oceanography studies seawater chemistry and chemical processes in the ocean. Chemistry, geochemistry, and oceanography can provide a strong foundation.
Geological oceanography focuses on the seafloor, sediments, plate tectonics, and other geological processes. Geology, geophysics, and earth science are common paths.
Because oceanography is interdisciplinary, the courses you complete can be just as important as the exact name printed on your degree.
What Classes Are Required for Oceanography?
Requirements differ among universities, but oceanography students commonly study a combination of:
- biology;
- chemistry;
- physics;
- calculus and other mathematics;
- statistics;
- geology and earth science;
- computer science;
- oceanography and marine science.
The balance depends on the specialty. Physical oceanographers generally need especially strong mathematics and physics backgrounds, while biological oceanographers typically take more biology and ecology.
Modern oceanography also relies heavily on data, so programming and quantitative skills are useful. Students may benefit from learning Python or another scientific programming language, statistics, GIS and mapping software, data visualization, and numerical modeling.
Laboratory courses can provide experience with scientific instruments and sample analysis, while field courses may introduce students to data collection techniques used in coastal and marine research.
How to Gain Experience While Studying Oceanography
A degree provides the scientific foundation, but practical experience can make a student much better prepared for graduate school or an entry-level position.
- Join university research projects. Ask professors about opportunities to assist with data analysis, laboratory work, field sampling, or ongoing research.
- Apply for internships. Government agencies, universities, laboratories, and research organizations offer programs for undergraduate and graduate students.
- Build laboratory experience. Learning to handle samples, instruments, and research procedures can be useful even if your eventual work is mainly computational.
- Participate in fieldwork when possible. Some programs offer coastal studies or opportunities aboard research vessels.
- Develop data skills. Practice programming, statistics, GIS, and working with large scientific datasets.
For example, NOAA Ocean Exploration lists internships, fellowships, and student programs involving ocean mapping, data analysis, research, and in some cases experience aboard research vessels.
Not every oceanographer spends long periods at sea. Some scientists primarily work with satellite observations, computer models, laboratory samples, or previously collected datasets. The amount of fieldwork varies substantially by specialty.
How Long Does It Take to Become an Oceanographer?
A bachelor’s degree usually takes about four years after high school and may be enough to begin working in certain entry-level scientific or technical roles.
A master’s degree commonly requires another one to three years, depending on the program, research requirements, and whether the student studies full time.
A PhD requires several additional years of advanced study and original research. The exact length varies considerably by university, specialty, research project, and dissertation progress.
There is therefore no single required timeline for becoming an oceanographer. Someone entering a technical position may begin after completing a bachelor’s degree, while a scientist planning to lead independent research or pursue an academic career may spend considerably longer in graduate school.
