The objectives for Expedition 333 were to core and measure temperature within the shallow intervals at IODP Sites C0011 and C0012 that were not adequately sampled during IODP Expedition 322 and to collect up to 220 m of additional basement material from Site C0012 (Fig. F1). These are the two subduction inputs sites for the Kumano transect, positioned above and on the northwest flank of a prominent basement high in the Shikoku Basin. Additionally, the coring objectives of an Ancillary Project Letter (738-APL), Nankai Trough Submarine Landslide History (NanTroSLIDE), were attempted to correlate the history of submarine landslides along the lower forearc slope to the history of slip along the megasplay fault. |
