We are extremely pleased to announce that the SEG decided to choose Dirk Gajewski from the WIT Hamburg team as Europe Honorary Lecturer for 2019. The topic of his lecture will be Wavefront attributes – A tool for processing, imaging, and model building. This choice constitutes a major honour and is a recognition of Dirk's excellence.

If there is a guiding theme in Dirk’s scientifc life, it is wavefronts and attributes. In the early years he used a model-driven approach in his work on ray…

Boris Kashtan from St. Petersburg State University is currently visiting the WIT Hamburg team as a research scientist until the end of October. The fruitful collaboration with Professor Kashtan has led to significant insight in the past, particularly in the development on new methods. You can find these in the annual WIT reports as well as, of course, in journal publications. We are very pleased that Boris is again in Hamburg. In addition to research, he will offer a lecture on Ray Method in…

During this year's EAGE conference in Paris, there will be a full-day workshop on “Linking Active and Passive Seismics”. The aim of the workshop is to bring together experts from the active and passive seismic communities to take a step forward in improving the technological exchange between both fields, in order to seamlessly blend reflection seismic data (particularly diffractions) with passive seismic data for improved localization, model building and imaging in both fields. Conveners are U.…
