Ziel der Reise / Objectives of Cruise:
During the SONNE cruises SO98/1 and SO98/2 multichannel reflection seismic, gravimetric, magnetic and hydroacoustic measurements were carried out along 21 lines with a total length of 3320 km. In addition, 3500 km were surveyed without reflection seismics. On 3 lines with lengths between 120 and 150 km, wide-angle/refraction seismic measurements were carried out. Purpose of the cruise was the investigation of the extend and the structural variability of the oceanic crust, the search for splinters of oceanic crust within the accretionary wedges at the subduction zones and the determination of the age of the oceanic crust. Furthermore, it was looked forf bottom-simulating reflectors (BSR) which indicate gas hydrates in the sedimentary sequence.
