The operations schedule for Expedition 316 is derived from the original Integrated Ocean Drilling Program (IODP) drilling Proposals 603-CDP3, 603A-Full2, 603B-Full2, 603C-Full, and 603D-Full2 (available 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 (PMT) with formulating a strategy for achieving the overall scientific objectives in these proposals. The resulting overarching goals and multistage implementation strategy is described in Tobin and Kinoshita (2006a, 2006b). For the first stage of the NanTroSEIZE project, the IODP Operations Committee scheduled three Chikyu ( These three expeditions will be implemented as a single science program.

Expedition 316 is scheduled for the Chikyu, operating under contract with the Japanese Implementing Organization, Center for Deep Earth Exploration (CDEX) and will begin directly following the completion of IODP Expedition 315 (Megathrust Riser Pilot, Chikyu) in mid-December 2007. At the time of publication, the ship schedule has not been completely finalized. Refer to for more information. For the current detailed schedule, see Details on the Chikyu can be found at A total of 49.5 days including 9.5 days of contingency time will be available for the drilling, coring, downhole measurements, logging, and casing operations described in this report.
