Ziel der Reise / Objectives of Cruise:

R/V Sonne cruises SO-224 and SO-225 are part of the cooperative project MANIHIKI II between GEOMAR and the Alfred Wegener Institute for Polar and Marine Research (AWI), funded by the German Ministry of Education and Research (BMBF). This multidisciplinary project continues previous research at the Manihiki Plateau conducted since 2007 (SO-193) on morphological, volcanological, geochemical, and geochronological studies and is now broadened by geophysical and paleoceanographic research foci. SO-225 focused on the stratigraphically controlled sampling of the igneous successions of the Manihiki Plateau. This has been accomplished by using the remotely operated vehicle ROV Kiel 6000 and chain bag dredges. Coring of deep sea sediments and sampling of the overlying water column has been added to the program. Subsequent shore-based research in the home institutes addresses the following aspects: (1) the temporal, spatial, and compositional evolution of the igneous basement of Manihiki Plateau; (2) the environmental impact of the large volcanic eruptions, which formed the Manihiki Plateau; (3) the dynamics and evolution of the West Pacific Warm Pool during the last ~3 million years, the potential oceanographic interaction between the equatorial Pacific and the Southern Ocean and its climatic responses. The integration of scientific results from SO-224 and SO-225 with existing data from the West Pacific large igneous provinces Manihiki, Hikurangi, and Ontong Java will contribute towards a better understanding of the origin and effects of volcanic mega events, the formation of large igneous provinces, and the paleoceanography and paleoclimate of the equatorial West Pacific.
