Ocean Processes and Ecology
OS130/230 Ocean Processes and Ecology
This site will be updated as the course progresses.


Course objective
At the conclusion of this course, students should possess a basic knowledge of biological oceanographic processes, and how these processes interact with the Earth's physical and chemical environment.  Outstanding problems currently facing biological oceanographers will be discussed, as well as current attempts and methodologies to address them. Students will demonstrate their accomplishment of these objectives by satisfactory performance on two examinations, by completion of assignments, and by satisfactory participation in class discussion.

Course evaluation
The format of the class is based on lectures combined with class discussion of key papers, and presentations by the students. Discussion sections will provide an opportunity to discuss the lecture material, present the papers (from the literature), and review homework assignments.


Evaluations: Students will be evaluated principally on the basis of their midterm exam (25%), final exam (25%), discussions of journal articles and homework assignments (20%), proposal/term paper and presentation (20%), and participation/attendance (10%). Graduate students are expected to be ranked in the upper 1/3 of the class, and expectations fofr assignments and exams are different for undergraduate and graduate students. Undergraduates will be evaluated and graded separately from graduate students.

Homework Assignments: Approximately weekly assignments will be given out in the lectures. Throughout the quarter, we will also be discussing journal articles related to the lecture materials. Students will provide one (written) question prior to the paper discussion, and will be assigned to either lead the discussion or moderate the questions.

Presentations: For journal article discussions, student leaders will present the key concepts of the paper, and lead the class in a review of its importance to the field of biological oceanography. All presentations will be required to use only the chalkboard (no overheads, no PowerPoint).

Proposals: Graduate students will prepare an NSF-style (10 pages, not including references) proposal on some topic related to biological oceanography. Undergraduate students will prepare a term-paper on a biological oceanographic subject, between 7-10 pages in length. Both groups will present their proposal/paper to the class at the end of the term, using Power Point.

Attendance Policy. Attendance at lectures is strongly encouraged since both the lecture and text materials will be included on homework and examinations.
Plagiarism Policy. Students are expected to do and turn in their own work. Cheating and/or copying is not tolerated, and will result in an automatic failure for the assignment. Please refer to University policy for the difference between citations and plagiarism; students are responsible for stated University policies.

ADA statement: The Americans with Disabilities Act (ADA) is a federal anti-discrimination statute that provides comprehensive civil rights protection for persons with disabilities. If you believe you have a disability requiring an accommodation, please contact the instructor and your TA as soon as possible after the beginning of class.

Exams will consist of a mixture of short answers, and longer essays that will require synthesis of ideas.
