In the framework of GEOP-502, 3 teaching sessions (almost 8 hours) on GEOSOFT-OASIS software were given by Dr. Alexandros Stampolidis, Asc. Res. Professor of Aristotle University of Thessaloniki Greece and Research fellow of Geological Survey of Norway (NGU) as an invited speaker. Our MSc students learned how to use GEOSOFT software and how to process (filtering, data enhancement, 2D and 3D inversion) real data. All lectures were recorded and videos are available to all faculty members and students.
