During trial cruise P3, RV Sonne was used by the Marine Seismic group of BGR (Federal Institute for Geosciences and Natural Resources, Hanover) and the Marine Sensor group of the ICBM (Institute for Biology and Chemistry of the Sea, Oldenburg).
The main objectives for the BGR group were to initialise and configure all components of a recently purchased 3D marine seismic data acquisition system and subsequently to operate the complete system to acquire a 3D data set in an area of limited extent. A second goal was to estimate the sound pressure level of BGR's seismic sources. The ICBM team aimed to test all installed oceanographic sensor systems and laboratories onboard the new research vessel plus test their own oceanographic sensors.
A low traffic area in the British sector of the North Sea with water depth deeper than 40 m was selected for all operations.
