Formal Lectures: 24 x 45 minute lectures will provide an introduction to the underlying theoretical principles of (1) modelling oceanographic phenomena using dynamical and thermodynamical principles and (2) ocean data collection and processing. The lectures will present factual information about the topics and methods in the syllabus and give explanations of how to put this knowledge into practice. Some lectures will contain interactive elements, including peer to peer instruction and problem solving within groups. Where relevant, lecturers' own research experience in the appropriate fields is brought into the lecturing sessions. References to the applicable chapter of course text and/or other relevant journal articles are provided as useful reading for each lecture.

Practical sessions: 12 x 2 hour sessions provide hands-on experience of processing and analysing different types of data using appropriate analytical computer tools. These sessions exemplify the theoretical concepts for data analysis covered during formal lectures allowing you to develop particular skills of relevance to both local and global-scale oceanographic analysis.

Support: is provided by staff and/or postgraduate demonstrators.

A wide range of support can be provided for those students who have further or specific learning and teaching needs.
