CEOAS Physical Oceanography is seeking students with a strong background in physics, mathematics, or applied sciences to study with us. Research areas include:

- turbulence and ocean mixing
- internal waves and nonlinear dynamics
- coastal processes
- climate and large scale dynamics
- physical/biological interactions
- numerical modelling and techniques
- instrumentation development
- ocean observations all over the world (examples include Hawaii, Chile, Spain, Taiwan, NJ, NC, WA and of course Oregon and more)

Most students accepted for study receive Graduate Research Assistantships (GRA) covering tuition and living expenses.
Numerous GRA openings are available in the above areas and more starting Fall 2018.

The academic program in physical oceanography at OSU offers Master's and Ph.D. degrees in Oceanography with a concentration on physical oceanography. The course curriculum is closely integrated with the wide range of physical oceanographic research conducted by OSU Physical Oceanographers. During the first year, students take a course on descriptive physical oceanography and a comprehensive 3-quarter course sequence on Geophysical Fluid Dynamics. First-year students may also take interdisciplinary courses in other oceanographic disciplines, as well as courses offered in the Mathematics Department at OSU. During subsequent years, students can choose from courses on a wide range of physical oceanography topics, including turbulence, geophysical waves, stability of geophysical fluid flows and coastal and estuarine oceanography. Technique oriented courses are also offered on topics including experimental methods in physical oceanography, satellite remote sensing, data analysis, numerical modeling and data assimilation. Brief overviews of each physical oceanography course are given below.

*Courses that are normally offered every year are marked with an asterisk. All other courses are usually offered alternate years.
