3 11) Programme Structure and Features: Target Intake students in the first year (2008/09), rising to students per year in subsequent years. Fees Standard taught MSc for School of GeoSciences. Degree Criteria MSc is full-time (12 months) or part-time (24 months). Progression to MSc or award of a Diploma in Exploration Geophysics will be determined based on the criteria specified in the University s Assessment Regulations. Taught Component The taught component consists of courses of lectures (all at SCQF level 11 and totaling 120 credits): 5-6 courses in the first semester and 5-6 in the second semester. All students attend and complete the seven compulsory core courses, two in semester 1 and five in semester 2. Students must achieve a minimum of 50% in each of their 7 core courses to progress to the research dissertation stage. Progression of any students who do not achieve this minimum to a Postgraduate Diploma in Exploration Geophysics will be determined as specified in the University s Assessment Regulations.

5 12) Further comments: a. Transferable skills. This is a generic existing course, and will be shared with other courses. Suggest to use the college Research, Design and Project Management which spread through out Semester 1, with 2 hours per week. Note that the students taken on this courses will not attend the PG conference in W12, and will be accessed differently. W12 is reserved for the field trip. b. Fundamental this is a new course with 20 credits, and it is recommended for students with a first degree in geology, and it is a optional for other students from physics or geophysics background. It could be taught by any numerate member of the school. c. Introduction to Geophysics, 10 credits. This course was given by Andrew Curtis for GEOSEAD, which will be withdrawn. It will be adapted for this degree and is recommended for students with a geology background. d. Introduction to geology. This is new course created for CCS (Carbon Capture and Storage), and it is recommended for students from a physics/geophysics background. e. The next two course, time signal analysis/inverse theory and wave theory will be adapted from the existing 4 th year courses. The teaching contents are mostly the same as the 4 th year courses, but they will be assessed differently at level 11 (MSc). f. The next four course, namely, structural geology, seismic sequence stratigraphy, petroleum systems and reservoir digenesis, are all existing GeoSEAD course which can be shared with this degree course, if appropriately time-tabled! g. The next course, carbon storage geology, is created for CCS, and is also available for Exploration Geophysics. h. This field course is a revised version of the existing EU field trip for the 4 th year geophysics. The existing course is held across EU, but the adapted course will be held around Edinburgh to accommodate the MSc time table. It is a core course i. Rock Physics is a new course, and the course will be shared between Ian Main and Mark Chapman, and attached for more details j. Advanced Geophysics Methods is a new course, and will be given jointly by Xiang- Yang Li and Professor Colin MacBeth from Herriot-Watt University. This new course will be part of the collaboration under ECCOSS. k. Seismic interpretation is a new course. 13) Outline of new courses: Fundamental Mathematics

12 Appendix B: GEOSCIENCES: NEW MSC BUSINESS PLAN FORM This form must be submitted in conjunction with a Draft Programme Specification and the associated financial spreadsheet to GO for agreement to take a proposal for a new MSc programme to School Board of Studies. (The details requested on this form are also required by College after BoS approval.) 1. SUMMARY INFORMATION - please insert the requested information into the boxes below Programme Title Programme qualification Host School Name of proposer(s) Name of intended Programme Director MSc on Exploration Geophysics 1 st degree, math, physics, geology, School of geoscienses Xiang-Yang Li, Andrew Curtis, Ian Main Xiang-Yang Li Duration of study Full time months (tick as applicable, and give months for FT) Part time 24 months Mode of study / delivery (tick as many as applicable) Resident at Edinburgh University Resident at another HE institution Collaborative Distance learning Flexible training package Date of intended first intake 1 October MARKET INFORMATION (i) Explain how you have assessed the potential demand for this programme. (including where appropriate information from the Recruitment and Admissions Liaison Service; International Office; Careers Service; employers; professional bodies; students etc) Demand for geophysicists has remained high, particular in the face of high oil-price, and sustainable energy growth will always be a critical issue to the modern society. Career prospects for students with an MSc will be very good for the foreseeable future. Starting salaries are around 25,000pa, with additional benefits for working overseas and/or offshore. Some students take up related careers such as IT or finance sector jobs, government agencies, or continue to higher degrees. Most students join service-sector, oil and gas, or minerals companies, and many have these destinations secured well before the end of the course. Employment circumstances look good for such students, therefore should be demand. Several oil company including Total expressed interest on such a course (ii) Summarize comparable provision and student numbers at competitor institutions.

13 there are strong competitor programmes (Leeds, IC) whose numbers total to perhaps 50, so competition is tough. Competitors are (apparently) over subscribed. As far as overseas students are concerned, among the three courses, Imperial College has the geographic advantage, and Edinburgh would rank at the 2 nd place in this regards. Apparent, Leeds would be the one losing out. However, for domestic and EU students, Edinburgh would come first, ranking ahead of Imperial college, because the science leadership in this area. As stands at the moment, Edinburgh is the centre for seismic research, with the association with Edinburgh Seismic Research, and ECCOSSE. Leeds advantage is its track record. Edinburgh also features a strong link to the Chinese Petroleum Industry through the Edinburgh Anisotropy Project 3. FINANCIAL ASPECTS See enclosed spreadsheet
