Summary module description:
After discussing the observational difficulties involved in studying the oceans, this module shows how observed large scale Features can be rationalised in terms of simple dynamical theories.

Aims:
To give an overview of modern approaches to the observational, numerical and theoretical study of the oceans, in order to provide the student with the required tools to address the current challenges of understanding how the oceans interact with the climate system.

Assessable learning outcomes:

By the end of this module, the students should be able to:

• Explain how the oceans works and how it interacts with the climate system;

• Make quantitative estimations of dynamical variables from hydrographic observations;

• Possess a basic understanding of the design of numerical ocean models, and of what can be learned from them;

• Solve basic problems in ocean dynamics.

Additional outcomes:
Students will get a good idea of typical values of important parameters in the oceans. Furthermore, they will improve their skill in problem solving, algebra, and understanding mathematical equations in physical terms.

Outline content:

1. Overview of the large-scale ocean circulation; methods of observing the large-scale circulation and observational difficulties;

2. Dynamical equations governing the oceans. Wind-driven circulation theory. The Ekman, Sverdrup, and Stommel models. Western boundary currents;

3. Thermohaline circulation: mechanically-driven or buoyancy-driven? Energetics and thermodynamics of turbulent mixing in stratified fluids. Multiple equilibria. Link with the merid ional transport of heat, and climate. Ocean heat uptake and sea level rise;

4. Theory of the Antarctic Circumpolar Current, role of the southern oceans and meso-scale eddies in the global circulation.

Brief description of teaching and learning methods:

Lectures and practicals.Practicals consist of 4 or 5 problem classes, depending on the year, during which students work on a problem under the guidance of the lecturer.
