651-4014-00L | Tomographic Imaging | 3 credits | 2G | T. Diehl, F. Lanza, A. Obermann | |

Abstract | This course provides an overview on the most widely used seismological methods to image the Earth’s interior with a focus on crustal and upper-mantle structures. Topics include controlled source methods such as refraction and wide-angle reflection, as well as passive body-wave and surface-wave based methods. The course will discuss the strengths and weaknesses of each method. | ||||

Learning objective | Understand the strengths and weaknesses of various active and passive tomographic methods to image the structure of the Earth. | ||||

651-4271-00L | Data Analysis and Visualisation with Matlab in Earth Sciences | 3 credits | 3G | G. De Souza, A. Obermann, S. Wiemer | |

Abstract | This lecture and the corresponding exercises provide the students with an introduction to the concepts and tools of scientific data analysis. Based on current questions in the Earth Sciences, the students solve problems of increasing complexity both in small groups and singly using the software package MATLAB. Students also learn how to effectively visualise different kinds of datasets. | ||||

Learning objective | The following concepts are introduced in the course: - Working with matrices and arrays - Programming and development of algorithms - Effective data analysis and visualisation in 2D and 3D - Learning to effectively use animations - Statistical description of a dataset - Regression analysis - Testing hypotheses |
