Ziel der Reise / Objectives of Cruise:

Cruise POS-405 aims at testing new equipment developed within the SUGAR project. A new Seabeam SBE 3050 multibeam system by ELAC Nautik was hull-mounted to R/V POSEIDON during the recent dry dock refurbishment. This multibeam system is capable to record the water column and display gas bubbles in the water column image (WCI) viewer. Successful tests of the system were completed during bathymetric mapping of the upper reaches of the Danube canyon. The second newly developed system, a deep-towed multichannel seismic streamer was deployed for the first time. Elaborate system tests using a deep-sea cable and winch were completed and first seismic signals could be recorded. After an intermediate port call with exchange of scientific crew a new bottom towed controlled electromagnetic source system was also tested. For the first time a 700 m long receiver array was towed behind the bottom deployed transmitter.
