651-4096-00LInverse Theory for Geophysics I: BasicsW+3 credits2VH. Maurer, A. Fichtner
AbstractThis course provides an introduction to inversion theory. The focus is rather on the basic principles and applications than on rigorous mathematical proofs. Prerequisites for this course include (i) basic knowledge of analysis and linear algebra and (ii) knowledge of Matlab (required for the exercises).
ObjectiveAfter this course the students should have a good grasp of geophysical inversion problems. In particular, they should be familiar with linear and non-linear inversion techniques. Most importantly, they should be aware of potential pitfalls and limitations of the methods.
ContentDuring this course, the following topics are covered:

- Introduction to geophysical inversion
- Matrix inversion techniques
- Linear inversion problems
- Non-linear inversion problems
- Probabilistic inversion approaches
- Global optimizers

Most of these modules are accompanied by exercises
Lecture notesPresentation slides and some background material will be provided.

AbstractIn Earth's core, motions of liquid iron act as a dynamo producing the geomagnetic field. This course explores the composition, structure and physical conditions in Earth's core and describes the geomagnetic field before focusing on the geodynamo mechanism. An interdisciplinary perspective is adopted involving electromagnetism and fluid dynamics but also seismology and mineral physics.
ObjectiveThe objectives of this course are:
(i) Development of the geophysical and sometimes mathematical tools
needed to understand Earth's core and the geodynamo.
(ii) Acquisition of knowledge concerning physical and observational constraints on the dynamics of Earth's core and the evolution of the geomagnetic field.
Content(i) Structure and composition of Earth's core: Including PREM, Adams-Williamson equation, Inner core anisotropy, Geochemical constraints, High Pressure mineral physics Experiments, Phase changes, Adiabatic temperature profiles, Geotherms, Power sources for the Geodynamo.
(ii) Observational geomagnetism: Spherical harmonics, Global field models, Westward drift, Jerks, Core field inverse problem, Core field structure and historical evolution, Polarity excursions and reversals, Time-averaged field.
(iii) Theory of the Geodynamo: Review of Maxwell's equations, Induction equation, Alpha Effect and Omega Effect, Proudman-Taylor theorem Geostrophy, Rotating Convection, Experimental and numerical dynamos.
Prerequisites / NoticeThe Earth's Core and Geodynamo Course capitalizes on the knowledge of:
- 651-4001-00L: Geophysical Fluid Dynamics
- 651-4130-00L: Mathematical Methods
Therefore we recommend that the students have attended those courses or others of similar content.

Prerequisite: Successful completion of Mathematical Methods (651-4130-00L) required.
W+3 credits2GA. Kuvshinov, A. Grayver
AbstractThe course will guide students in learning about deep electromagnetic (EM) studies of the Earth. These studies focus on analysis and interpretation of long-period time-varying EM field observed at Earth's surface, at sea bottom and at satellite altitudes with ultimate goal to recover electrical conductivity distributions in Earth's interior.
ObjectiveGoverning equations for these studies are Maxwell's equations and special attention in this course will be paid to the solution of Maxwell's equations in Earth's models with one-dimensional (1-D) and three-dimensional (3-D) conductivity distributions. In addition the basics of inverse problem solutions - as applied to deep EM studies - will be discussed.
ContentIntroduction to deep electromagnetic (EM) studies of Earth (governing equations, conductivity models under consideration, summary of the main EM sounding methods, etc.); basics of magnetotelluric (MT) and geomagnetic deep sounding (GDS) methods; solution of Maxwell's equations in fundamental (layered) Earth's models in Cartesian and spherical geometries; solution of Maxwell's equations - based on integral equation approach - in Earth's models with 3-D conductivity distribution (theory and efficient numerical implementation); solution of EM inverse problems (inverse problem formulation, regularization of the inverse solution, discussion on optimization methods and adjoint approach); basics of data processing; examples of application (use of MT to detect geothermal reservoirs; use of GDS to constrain mantle conductivity; 3-D EM modellings to predict space weather hazards, etc.)

After short introductions to various applied geophysical methods, strategies for resolving a wide variety of exploration, engineering and environmental problems are introduced. Themes addressed in exploration geophysics include exploration and evaluation of marine hydrocarbon reservoirs. Themes addressed in engineering geophysics include: remote sensing in archeology, detection of metal pipes, plastic pipes and caverns in the subsurface, and characterizing the shallow underground in regions of major construction. Themes addressed in environmental geophysics include: exploration and evaluation of groundwater reserves, and investigations of potentially dangerous waste disposal sites (e.g. outlining the boundaries and content of poorly documented landfills and studies of sites for the future storage of chemical and radioactive refuse).
