NFYK14027U Steady Ocean Circulation
MSc Programme in Physics
In this course we will discuss three of the world's ocean major circulation systems and how they support the marine ecosystem: the subtropical gyre, the Antarctic Circumpolar Current, and the meridional overturning circulation. The focus will be on the manipulation of the equations of motion to derive simple analytical models of these systems. Observations and numerical models will then be used to fill these equations with life.
The purpose of this course is that the student obtains a basic understanding of the dynamics of the large scale circulation, and the carbon cycle.
When the course is finished it is expected that the student is able to:
- Explain and apply the concept of potential vorticity
- Explain the energetic of the meridional overturning circulation
- Understand the relevance of friction and mixing for the ocean circulation
- Explain the main components of the marine carbon cycle.
The course introduces the student to the equations of motion for a continuous medium. The student will learn how to use scaling analysis to reduce the complexity of partial differential equations. Finally the student will combine the resulting equations with observations and numerical model results to relate the different forcing mechanisms to the relevant part of the ocean circulation.
