Purpose
Abstract The research area during SO266 is located in the SW off Taiwan. The main focus of the cruise was the investigation of gas hydrate distributions influenced by different tectonic settings (at active and passive margins) and lithologies using the MEBO200 to collect sediment samples. The ship-mounded multibeam echosounder was used to collect detailed information about the drill sites containing bathymetry and backscatter data as well as water column information. The EM122 was recording continuously during the cruise. To avoid signal interferences all used hydroacoustic systems were synchronized using the on-board K-Sync-Unit. During the hydroacoustic surveys the vessel speed was conducted to 11 kn. The vessel velocity was lowered to 3 kn for flare imaging surveys. The data quality was generally good, due to the good signal to noise ratio of the research vessel.
