Ziel der Reise / Objectives of Cruise:
Objectives During trial cruise P3 of RV Sonne the vessel was used by the Marine Seismic group of BGR (Federal Institute for Geosciences and Natural Resources, Hannover) and the Marine Sensor group of the ICBM (Institute for Biology and Chemistry of the Sea, Oldenburg). Main objectives for the BGR group were to initialize 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 team of ICBM aimed on testing all installed oceanographic sensor systems and laboratories onboard the new research vessel plus to test 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. Narrative After several days of installing all equipment RV Sonne moved to the designated working area September 6th. The working program commenced September 9th with bathymetric surveying and first tests of the ADCP sensors. Starting on September 9th a hydrophone buoy and two seismic airgun arrays were deployed. The predefined full day operation plan was successfully completed by 8:00 p.m. During the night testing of oceanographic sensors (CTD, ADCP) was continued until September 10th , noon. In a second part of the sound immission program a single GI-gun was used unitl 7:00 p.m. During the night oceanographic testing was continued again. The oceanographic sensors testing had to interrupted on September 12th when the paravans of the 3D seismic systems were deployed. After comprehensive testing of deflection properties of the paravans under various rigging the first of the two streamers was deployed on September 14th. Starboard layout including seismic source (GI-gun) was set up September 15th followed by deployment of the portside streamer. Night time was again used for oceanographic testing. Portside paravan and seismic source were deployed September 16th at moderate sea and wind conditions. Starting at noon a limited 3D seismic data acquisition along a limited number of preset seismic lines was started for training purposes. 3D seismic surveying was stopped Septmeber, 17th 7:00 a.m. and all outboard components were retrieved. During September 18th all equipment was deinstalled and packed into the containers. While conducting the 3D seismic program bathymetric surveying, testing of echosounders, oceanographic sensors and laboratory equipment was continued. RV Sonne set for transit Septmeber 18th in the evening and called the port of Bremerhaven September 19th.
