Abstract | The scientific goals of the first leg of SO173 centered around geophysical investigations using OBH and OBS systems as well as DTS sidescan sonar and multichannel seismic streamer. Planned surveys included seismic measurements ranging from conventional crustal scale wide-angle surveys to high resolution deep tow seismic investigation and deep tow sidescan sonar imaging. The EM120 was used continuously during SO173-1. During deep tow profiling dense line offset was used to reduce the opening angles of the beams in order to receive higher resolution images while still covering the complete area. At the beginning of the cruise, a water velocity profile was measured to a depth of 2000 m. |
