651-4104-00LGeophysical Field Work and Processing: Methods2 KP3VC. Schmelzbach, M. Grab, H. Maurer
KurzbeschreibungThe 'Methods' part of 'Geophysical Fieldwork and Processing' provides an overview over the most common methods used in Applied Geophysics. Theoretical and conceptual aspects as well as data acquisition and processing of the methods used in the other two parts of the course are introduced.
LernzielStudents should (1) acquire a basis knowledge on theory and working principles of the most common techniques in Applied Geophysics and (2) acquire the necessary knowledge to plan, conduct, process and document a near-surface geophysics survey.
InhaltThe course is divided into four parts:

1. Introduction to the course held in the lecture hall (first lecture)

2. Online lectures and quizzes covering short reviews of the theory, techniques, acquisition and processing of:
- Ground Penetrating Radar (GPR)
- Electrical Resistivity Tomography (ERT)
- Magnetic Surveying
- Electromagnetic Induction Surveying
- Seismic Refraction Tomography

There will be a questions-and-answers session held in the lecture hall before the exam (second last lecture).

3. Practical exercise and field equipment demonstration (outdoor; location and date will be communicated during the introduction lecture). Participation in the practical exercise is a REQUIREMENT.

4. Written examination during the last lecture. A pass in this exam is a REQUIREMENT to continue with the second part of the course 651-4106-03L Geophysical Field Work and Processing: Preparation and Field Work.
SkriptAvailable over the ETH online lecture Moodle page.
Link will be given during the first lecture.

651-4106-03LGeophysical Field Work and Processing: Preparation and Field Work Information 7 KP3V + 11PC. Schmelzbach, M. Grab, P. Nagy, A. Wieser
KurzbeschreibungThe 'Preparation' and 'Field Work' parts of 'Geophysical Field Work and Processing' involve the planing and conducting of a near-surface geophysical field campaign using common geophysical techniques to study, for example, archeological remains, internal structures of landslides or aquifers. Students work in small groups, and plan, acquire, process and document a field campaign together.
LernzielStudents should acquire the knowledge to (1) design and plan a geophysical survey appropriate for the target of investigation, (2) acquire geophysical data, (3) process the data using state-of-the-art techniques and software, (3) analyze and interpret the results, and (4) write a report according to commercial and scientific standards.
InhaltThe course is split into two parts:

1. 'Preparation': Introductory lectures and exercises (lab and field) covering Geographical Information Systems (GIS), surveying, and introductions to the field sites. Participation in the 'Preparation' part is a REQUIREMENT to participate in the 'Field Work' part.

2. 'Field Work': Four-weeks field course. The students work in groups on the following topics:
- Planning and design of a comprehensive geophysical survey
- Data acquisition
- Data processing and inversion
- Interpretation of the results
- Report writing
SkriptRelevant reading material, manuals and instructions for all methods of the field course will be handed out to each group at the beginning of the 'Field Work' part (beginning of June).
Voraussetzungen / BesonderesA "pass" (Swiss grade 4.0 or higher) in the written examination of 651-4104-00 V Geophysical Fieldwork and Processing: Methods, is an absolute REQUIREMENT to participate in this course.
