Ziel der Reise / Objectives of Cruise:

The focus of R/V Sonne voyage SO251 - EAGER-Japan ?Extreme events Archived in the GElogical Record of Japan's Subduction margins" was to investigate fluid- and sediment mobilization processes by mud volcanism, earthquake-triggered seafloor displacement, submarine landslide and related "paleoseismologic event deposits" and to compare inferred earthquake processes and rates along accretionary vs. erosive subduction margins of Japan (Nankai Trough and Japan Trench, respectively). The first part of SO251 (Leg 1) started on Oct 4 from Yokohama to the Japan Trench off NE Japan. During the short voyage, which ended on Oct 15 back in Yokohama, we mapped the entire along-strike extent of the Japan Trench from 36? to 40.3? N, to now have a complete high-resolution bathymetric map of the trench axis and nearly 2000 km of subbottom Parasound profiles. We also succeeded to take six 10m long piston cores from more than 7000km water depth and three 5m long cores from the landward slope of the subduction system, which allow to document, compare and track the sedimentary processes and extreme-event deposits from the southern to the northern part of the plate boundary system along the Japan Trench subduction zone.
