Courses

Ocean Dynamics: propagating anomalies

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.
