The Geophysical Institute of the Mining University Leoben and the Institute of Applied Geophysics of Joanneum Research, a non profit research center of Styria, are regularly involved in reflection seismic surveys. Many of the surveys are run for research projects supported by official funds of the Ministry of Science and Research, by governmental institutions of the federal counties and by the Austrian Fund, for Industrial Support. There are however also important projects for the industry and private institutions like oil companies, organizations for the development of thermal- or mineral water resources or engineering bureaus. We use our own 48-channel digital Sercel 338 seismograph in the field. The data processing is dove with the DISCO-package of Cogniseis.
