Ziel der Reise / Objectives of Cruise:

R/V SONNE cruise SO265 is the central activity of the research project "Shatsky Evolution" that is funded by the BMBF and conducted by GEOMAR in collaboration with international partners. The goal of the project is the geological investigation of the late stage evolution of Shatsky Rise, a vast, submarine volcanic plateau in the northwest Pacific and in particular the transition from plateau volcanism (Shatsky Rise) to postulated hotspot track volcanism (Papanin Ridge and/or Ojin Rise seamounts). Applied methods included bathymetric mapping with the ships own EM 122 multi-beam echosounder (and PARASOUND sediment echosounding) and rock sampling by means of chain bag dredges. Dredge hauls were conducted between ~36? N and ~44?N and 163? E and ~170?E covering the entire geographic extent of Papanin Ridge and the Ojin Rise seamount province. In addition, a single dredge haul was successfully conducted at Hokkaido Trough (45?06 N, 162?27E). Collected rock samples will be used for volcanological, geochronological, petrological and geochemical analyses on shore. Furthermore, macro benthic organisms were sampled from the dredged rocks to study the diversity of deep-see invertebrates and sediment sampling (by small sediment traps installed in the dredges) was conducted for meiofauna studies.
