Schedule for Expedition 338

The operations schedule for Integrated Ocean Drilling Program (IODP) Expedition 338 is derived from the original IODP drilling Proposals 603-CDP3 and 603C-Full (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 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). For “Phase 2” of the NanTroSEIZE project described in Proposals 603B and 603D, the IODP Operations Task Force scheduled one Stage 1 expedition and one Stage 2 expedition on the D/V Chikyu, operating under contract with the Japanese Implementing Organization, the Center for Deep Earth Exploration (CDEX) (​chikyu/​eng/​Expedition/​index.html).

Expedition 338 is the second expedition of NanTroSEIZE Stage 3 and is currently scheduled to begin at Shingu, Japan, on 19 September 2012. Details of the operational schedule, updates to the drilling schedule, and operational and layout details of the Chikyu can be found at​chikyu/​eng/​CHIKYU/​index.html. The science party is scheduled to board the Chikyu on 6 October 2012 and disembark at Shingu, Japan, on 6 January 2013; the science party itself will consist of two groups, which will rotate on/off the week of 17–23 November 2012; 1 week will be spent in crossover with Specialty Coordinator participation. The entire expedition comprises a total of 102 days, including 20 days of contingency time, that will be available for drilling, coring, logging, and casing operations during Expedition 338, as described in this Scientific Prospectus.
