AbstractThis course focuses on benefits and limitations of geophysical methods applied to problems of high societal relevance. It is demonstrated, how seismics, ground-penetrating-radar and other electromagnetic methods can be employed in geothermics, the cryosphere, hydrocarbon exploration, natural hazard assessments and radioactive waste disposal problems.
Learning objectiveThis course is set up for both, geophysicists and non-geophysicists. The former will become familiar with applications of geophysical methods, for which they have learned the underlying theory in other courses. Non-geophysicists (i.e., potential users of geophysical technics, such as geologists and geotechnical engineers) will learn, which geophysical method or which combination of geophysical methods can be used to solve a particular in their realm.

The main learning goal for both groups is to understand the benefits and limitations of geophysical techniques for important applications, such as exploration problems, waste disposal, or natural hazards.
ContentDuring the first part of the course, various themes will be introduced, in which geophysical methods play a key role.

Module 1 (24.2./3.3): Geothermal Energy (M. Saar)

Module 2 (10.3./17.3.): Radioactive Waste Disposal (T. Spillmann)

Module 3 (24.3.): Natural Hazards (H.R. Maurer)

Module 4 (31.3.): Cryosphere Applications (H.R. Maurer)

Module 5 (7.4.): Marine Seismics (J. Robertsson)

Module 6 (14.4.): Hydrocarbon Exploration (Fons ten Kroode)

During the second part of the course, we will focus on Deep Underground Laboratories. They offer exciting opportunities for research associated with many themes covered in Modules 1 to 6. This block starts with an introductory lecture (28.4.), followed by visits of the three main Deep Underground Laboratories in Switzerland:

5.5 .: Mont Terri Laboratory

12.5: Bedretto Laboratory

19.5.: Grimsel Test Site

The laboratory visits will occupy the full afternoons of the respective days. Of course, the visits will only be possible, when the COVID-19 situation will be appropriate. Otherwise, virtual laboratory tours are planned. For earning the credit points, at least two out of the three laboratory visits are mandatory, but the students are encouraged, to join all visits.

Active participation of the students will be required. Prior to the laboratory visits, the students must familiarize themselves with one experiment (in total, not per laboratory), and they will introduce this experiment during the visit to their fellow students. Finally, a short report on the experiment assigned will have to be written. Presentation and report will contribute 50% to the final grade.

The remaining 50% of the final grade will be earned during a project work on June 2. The students will receive a small project out of the themes of Modules 1 to 6. During a few hours, they will work independently on the project, and they have to summarize their results in a short report.
Lecture notesCourse material will be provided in the teaching repository associated with this course.

651-4094-00LNumerical Modelling for Applied Geophysics4 credits2GJ. Robertsson, H. Maurer
AbstractNumerical modelling in environmental and exploration geophysics. The course covers different numerical methods such as finite difference and finite element methods applied to solve PDE’s for instance governing seismic wave propagation and geoelectric problems.

Prerequisites include basic knowledge of (i) signal processing and applied mathematics such as Fourier analysis and (ii) Matlab.
Learning objectiveAfter this course students should have a good overview of numerical modelling techniques commonly used in environmental and exploration geophysics. Students should be familiar with the basic principles of the methods and how they are used to solve real problems. They should know advantages and disadvantages as well as the limitations of the individual approaches.

The course includes exercises in Matlab where the students both should learn, understand and use existing scripts as well as carrying out some coding in Matlab themselves.
ContentThe following topics are covered:
- Applications of modelling
- Physics of acoustic, elastic, viscoelastic wave equations as well as Maxwell's equations for electromagnetic wave propagation and diffusive problems
- Recap of basic techniques in signal processing and applied mathematics
- Solving PDE's, boundary conditions and initial conditions
- Acoustic/elastic wave propagation I, explicit time-domain finite-difference methods
- Acoustic/elastic wave propagation II, Viscoelastic, pseudospectral
- Acoustic/elastic wave propagation III, spectral accuracy in time, frequency domain FD, Eikonal
- Implicit finite-difference methods (geoelectric)
- Finite element methods, 1D/2D (heat equation)
- Finite element methods, 3D (geoelectric)
- Acoustic/elastic wave propagation IV, Finite element and spectral element methods

Most of the lecture modules are accompanied by exercises Small projects will be assigned to the students. They either include a programming exercise or applications of existing modelling codes.
Lecture notesPresentation slides and some background material will be provided.

651-4104-00LGeophysical Field Work and Processing: Methods2 credits3VC. Schmelzbach, H. Maurer
AbstractThe '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.
Learning objectiveStudents 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.
ContentThe 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 before the exam.

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.
Lecture notesAvailable over the ETH online lecture Moodle page.
Link will be given during the first lecture.
