Courses

Ocean Dynamics: steady circulation

Description: 

The participant will be introduced to the main concepts of Ocean Dynamics for rotating and stratified turbulent fluids. The course is structured around ten main topics, each to be covered in one day. Each topic will have a theoretical background, where fundamental concepts will be discussed, and a practical exercise, where a laboratory and/or computer exercise will be discussed, developed and applied. After completing the course the participant will have an intermediate knowledge of the major blocks underlying the dynamics of ocean circulation and mixing.

"Great experience. What I liked best was that lessons incorporated real life examples and concept-based illustrations as much as possible. This has enabled me to follow physical mechanisms of ocean dynamics more easily than before. Good balance between the theory and practical sessions. Kudos to the instructors and organisors for doing such a great job!”
