Course Aim
The aim of the course is to introduce approaches to analysis of geophysical data based on inverse theory and explore some of the questions that arise in solving linear and non-linear inverse problems.

After completing the course, the student is expected to be able to:
• explain and apply fundamental principles of geophysical data inversion
• formulate solutions of geophysical problems using Tikhonov regularization technique
• process and evaluate quality of geophysical data
• obtains experience from inversion of real and synthetic data
• explain strength and weakness of geophysical methods
• explain and apply inversion techniques for potential field data
• explain and apply inversion techniques for electromagnetic data


Contents
Inversion of geophysical data: Characterization of data and data errors. What are the characteristics of a good model? Model parameterization and Tikhonov regularization. Forward responses and Sensitivities. Solving linear and non-linear inverse problems. Relation between data errors and errors on model parameters. Trade-off between resolution and parameter errors. Á priori information. Bayesian inversion. Examples with inversion of various types of geophysical data. Applications in mineral explorations and environmental investigations.

Realization
Each course occasion´s language and form is stated and appear on the course page on Luleå University of Technology's website.
The teaching will be as lectures and laboratory training. Participation in the laboratory training is compulsory. The lectures will be focused on basic theory and applications on geophysical data. The laboratory part will be focused on determination of physical properties of geological material and interpretation of geophysical data. Geophysical software packages are used to illustrate the interpretation and processing methods.

Examination
If there is a decision on special educational support, in accordance with the Guideline Student's rights and obligations at Luleå University of Technology, an adapted or alternative form of examination can be provided.
A written assignment exercise assesses the ability to formulate and solve simple inverse problems rising in petrophysical measurements by applying inverse theory methods (U/G). A written exam assesses the ability for problem-solving and describing fundamental principles of geophysical data inversion. The exam also evaluates the ability to formulate the inverse problem and explain solutions for geophysical methods presented during the course.
