Degrees Offered: MS in oceanography, PhD in oceanography

The Academic Program

Oceanography (OCN) is the study of the physics, chemistry, and geology of the ocean and the ecology of organisms that live within the sea. Physical oceanography is concerned with ocean circulation, waves, tides, upwelling, air-sea interactions, and the effect of the oceans on climate. Chemical oceanographers study the distribution of dissolved and suspended substances in the ocean and the mechanisms, both natural and anthropogenic, that control their form and abundance. Geological oceanography includes the study of sea-floor spreading, submarine volcanism, beach formation, deep-seabed mineral resources, sediments, and paleoceanography. Biological oceanographers study the interactions of marine organisms with one another and the environment; topics include coral reef ecology, marine fisheries, hydrothermal-vent communities, plankton ecology, and near-shore and deep-sea benthic communities.

Because Hawai‘i is located near the middle of the largest ocean on Earth, oceanography has a special significance for the state and UH Mānoa. The oceanography facilities at UH Mānoa are among the best in the U.S. and include three ocean-going research vessels and two research submarines. Biological studies are facilitated by the presence of the Hawai‘i Institute of Marine Biology on Coconut Island in Kāne‘ohe Bay. Computing facilities are based on a growing network of several hundred computers and servers. Precision instruments include mass spectrometers, gas and liquid chromatographs, a CHN analyzer, a flow cytometer, carbon analyzers, nutrient analyzers, and a series of atomic spectroscopy-based instruments. The world-class faculty is actively involved in both teaching and research. UH Mānoa ranks fifth among universities in the nation in terms of National Science Foundation research funding for oceanographic research. The location, the facilities, and the faculty all make UH Mānoa an ideal place to study oceanography.

About 40 percent of marine scientists are employed by the U.S. government, especially by the Departments of Defense, Commerce, and Interior. Another 40 percent teach and do research at academic institutions. About 20 percent are employed by industry.

The MS and PhD in oceanography are recognized WICHE regional graduate programs. Residents of several U.S. states and the Northern Mariana Islands are eligible, upon admission, to enroll at a reduced tuition of 150 percent of the institution’s regular tuition rate.


Each student admitted to the oceanography department is assigned an advisory committee by the department chair. The committee initially consists of three graduate faculty members from at least two of the subdisciplines of oceanography. When formed, the student’s MS or PhD committee becomes the student’s advisory committee. A student must meet with his or her advisory committee at least twice per year. A written report summarizing each meeting must be signed by the student and his or her committee and a copy is placed in the student’s file.

Graduate Study

The department offers master’s and doctoral programs with areas of specializations in biological and physical oceanography, and marine geology and geochemistry.

Oceanography courses listed in this Catalog may be taken for credit in the degree program. Additional courses may be selected from such fields as atmospheric science, botany, chemistry, engineering, geology, mathematics, physics, and zoology.

Admission Requirements

Applicants must have a rigorous training in one of the basic sciences or engineering. Regardless of major, an applicant must have completed mathematical training, including calculus through first-order ordinary differential equations (equivalent to Calculus IV at UH Mānoa). An applicant must also have a year each of physics and chemistry. The well-prepared student will also have covered classical thermodynamics and applied differential equations and will have had a semester each of biology and geology. Interested students should contact the department chair for further information. For U.S. applicants, the deadline for application for admission is December 15 for the fall semester and September 1 for the spring semester. For foreign applicants, the corresponding deadlines are December 15 and August 1.

Major Requirements

All students pursuing a degree program must take OCN 620, 622, and 623. For non-biological students, the sequence is completed by taking OCN 621. Biological students complete the sequence by taking OCN 626, 627, and 628. Marine geology and geochemistry students must take CHEM 351 (if they have not already successfully completed a college-level course in physical chemistry). Students may be admitted to the MS program upon successful completion of the appropriate sequence. To be admitted to the PhD program, a student must receive a positive recommendation from a PhD-qualifying committee.

Degree Requirements

Both the MS and PhD programs require a minimum of 36 credit hours, including 24 credit hours of course work. The 24 semester hours of course work must be in courses numbered 600 or above (excluding OCN 699, 700, 800, and seminar courses). At least 12 of those semester hours must consist of courses taken from three of the following groups: biological oceanography, geological oceanography, chemical oceanography, physical oceanography, mathematical methods and statistics, and atmospheric sciences. MS (PhD) students are required to write a thesis (dissertation) based on original research. For MS students, to ensure a minimum effort spent learning the proper conduct of research, a requirement of six credits of both OCN 699 and OCN 700 has been established, but usually more credits will be required to complete the thesis (about 12 more credits of OCN 699). No minimum requirement for OCN 699 or OCN 800 is set for PhD students due to the much larger effort that is always required to produce a PhD dissertation.

Prior to completion of their graduate degree, biological oceanography students must have satisfactorily completed either an undergraduate or graduate course in statistics. Students specializing in marine geology and geochemistry must take at least one, advanced geochemistry course. All students must complete a seminar requirement, demonstrate computer competency, and accumulate at least 30 days of field experience. PhD candidates must also pass a comprehensive examination. All students must pass a final oral examination in defense of their thesis/dissertation.
