Seminar Series

In 2008 the Geocomputing group initiated a seminar series consisting of talks related to various topics from the field of Geocomputing. The main focus is to address and discuss in an informal manner issues related to the projects currently on the way in the Geophysics section. Talks also deal with technical details of High-Performance Computing, numerical algorithms and software and tool related issues.

The following tables give an overview on past talks. The schedule for winter term 2021 can be found here.
