Schedule for Expedition 348

The operations schedule for Integrated Ocean Drilling Program (IODP) Expedition 348 is derived from the original IODP drilling Proposals 603-CDP3, 603B-Full2, and 603C-Full (available at​600/). 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 to achieve the overall scientific objectives outlined in all of the NanTroSEIZE program proposals. The overarching goals and multistage implementation strategy are described in Tobin and Kinoshita (2006a, 2006b).

Expedition 348 is the third expedition of NanTroSEIZE Stage 3 and is scheduled to begin at Shimizu, Japan, on 13 September 2013. Details of the operational schedule, updates to the drilling schedule, and operational and layout details of the D/V Chikyu (operating under contract with the Japanese Implementing Organization, the Center for Deep Earth Exploration [CDEX]) can be found at​chikyu/​eng/​CHIKYU/​index.html.

The Science Party will be on board for only the latter part of riser drilling operations, when we anticipate that collection of cuttings, core, and logging data will be ongoing and/or complete and shipboard analysis can begin. To ensure a scientific presence during the entire expedition, PMT members acting as Operations Liaisons will be on board during operations to drill and case IODP Hole C0002F from 860 to 2300 meters below seafloor (mbsf), prior to embarkation of the main science party. The schedules for the Operations Liaisons, Co-Chief Scientists, Expedition Project Managers (EPMs), and science party are listed in Table T1. The entire expedition comprises a total of 130 days, including 41 days of contingency time (Table T2).
