Ocean Ecology and Biogeochemistry

Ocean Ecology and Biogeochemistry is the study of the ocean's biological, chemical, and geological processes, and their interplay Most broadly, Ocean Ecology and Biogeochemistry is concerned with the structure and function of ecosystems across space and time, including feedbacks between land, atmosphere and ocean. Research backgrounds of our faculty include paleo-reconstruction, population and community ecology, biogeochemical cycling, atmospheric sciences, optics, acoustics, remote sensing, hydrology, deep-biosphere, and climate science. This diversity provides opportunities to break down traditional disciplinary boundaries and explore new lines of research, and to provide students with basic core knowledge of the traditional disciplines while encouraging them to work more closely at disciplinary interfaces in an earth system science context.

The Ocean Ecology and Biogeochemistry faculty employs diverse research tools to address challenging ecological and biogeochemical questions including field campaigns, laboratory experiments, remote sensing and numerical modeling. The research themes noted below loosely capture the general current research of the group, but is not comprehensive. Infrastructure and equipment within the college are state of the art and available to support graduate student research.


The CEOAS ocean ecology and biogeochemistry program is currently seeking students with a strong background in biology, chemistry, geology, earth or applied sciences to study with us. Most students accepted for study receive Graduate Research Assistantships (GRA) covering tuition and living expenses. Numerous GRA openings are available each year and are best investigated by first contacting individual faculty members whose research aligns with your interests. Prospective students should also check out the graduate student guidelines. Additional fellowship and funding opportunities can be found here.

The College offers other graduate and undergraduate majors, minors, and certificates (see Catalog College Overview). Faculty members at the College support paid summer research internships through Research Experience for Undergraduates (REU).
