In this course the response of the ocean to transient and steady winds and buoyancy forcing will beanalyzed in tropical and extra-tropical regions. The steady circulation (horizontal gyres,thermohaline circulation and ventilated thermocline) will be derived. A hierarchy of models, fromsimple analytical to realistic numerical models will be presented to study the role of the waves,convection, instabilities and other physical processes in the circulation of the oceans.
Basic knowledge of fluid mechanics, analysis and physics of basic and intermediate levels.

Attendance is required. Daily preparation is also required. The assignments are set out in the course syllabus. Academic honesty is an important part of university training. While students may discuss assignments with their classmates and others, they are expected to make sure any written material they submit is their own work. Students are expected to know how to cite the work of others and present a bibliography of the research texts that were used.
Participation 20%
Students are expected to play an active role in seminars and prepare the required readings in advance

Presentation of a short paper 40%
Each student will be required to present an extended abstract (max 4 A4 pages, figures included) on a particular issue approved in advance by the instructor. The oral presentation of the chosen topic will be scheduled by the instructor. Each individual oral presentation shall last 30 minutes and will be followed by discussion with other students and the instructor.

Final exam 40%
