Expedition 314 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 www.iodp.org/NanTroSEIZE). Following ranking by the IODP Scientific Advisory Structure (SAS), the IODP Operations Task Force created the NanTroSEIZE Project Management Team (NT-PMT) to formulate a strategy for achieving the overall scientific objectives in these proposals. The resulting overall goals and multistage implementation strategy are described in Tobin and Kinoshita (2006a, 2006b). For the first stage of the NanTroSEIZE project, the IODP Operations Task Force scheduled three expeditions by the Chikyu (www.iodp.org/expeditions). These three expeditions will be implemented as a single science program. Additionally, core sampling at several sites and installation of a borehole observatory were planned as part of Stage 1, but expeditions to carry out these objectives have been deferred to a later time. The supporting site survey data for the NanTroSEIZE Stage 1 expeditions are archived at the IODP-MI Site Survey Data Bank (ssdb.iodp.org).
The expedition is currently scheduled to begin from Shingu, Japan, on 21 September 2007 and to end on 16 November 2007 with helicopter transfer of the science party from the ship to the Ugata, Shima, in the Mie Prefecture, Japan. A total of 57 days, including 8 days of pilot hole drilling and 15 days of contingency, will be available for the LWD operations described in this prospectus. At the time of publication, the ship schedule has not been finalized and may change (see Table T1). Refer to www.iodp.org/expeditions for more information.
