COURSES

Chemical Oceanography is taught every year for incoming graduate students and interested students from other departments. The course meets three times per week. Two of those sessions are lectures and the third is used to discuss a journal paper or a problem in a cooperative-learning, class-room discussion environment. There are five journal article discussions and five problems. Course outline and reading are presented below.
