Beschreibungen/Notizen

• In the scope of the Integrated Seismics Oberpfalz 1989 (IS089) at the Oberpfalz continental deep drilling (KTB) location, a 3D expanding‐spread experiment was carried out by the DEKORP group in 1989. The vibrator signals of the 3D seismic survey were recorded with additional geophone spreads in such a way that a c. 40‐fold 2.6 * 3.8 km 2 CMP‐area centered at the KTB location was obtained. The source‐receiver offsets are in the range of 0–24 km and azimuth angles of 0–180° are achieved. The data set consists of 189, 460 seismic traces. The configuration and data description from this experiment are presented, and problems in the velocity analysis caused by geology, dipping reflections and anisotropy are discussed.
