The operations schedule for Integrated Ocean Drilling Program (IODP) Expedition 319 is derived from original IODP drilling proposals 603-CDP3, 603A-Full2, 603B-Full2, 603C-Full, and 603D-Full2 (available for download at

Following ranking by the IODP Scientific Advisory Structure, the IODP Operations Task Force charged the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) Project Management Team (NT-PMT) with formulating a strategy for achieving the overall scientific objectives outlined in these proposals. The overarching goals and multistage implementation strategy are described in Tobin and Kinoshita (2006a, 2006b). For "Phase 2" of the NanTroSEIZE project described in proposals 603B and 603D, the IODP Operations Committee scheduled one Stage 1 expedition and one Stage 2 expedition on D/V Chikyu, operating under contract with the Japanese Implementing Organization, Center for Deep Earth Exploration (CDEX) (

Expedition 319 is the first expedition of Stage 2 and is currently scheduled to begin directly following the completion of shakedown for the new drill-rig operators, Mantle Quest, Japan. At the time of publication, the ship schedule has not been completely finalized and readers should refer to for detailed schedules, updates, and information regarding the operation and layout of Chikyu. A total of 114 days including 27 days of contingency time will be available for the drilling, coring, logging, and casing operations during Expedition 319, as described in this prospectus.
