Schedule for Expedition 322

Expedition 322 evolved from the original Integrated Ocean Drilling Program (IODP) drilling Proposals 603-CDP3, 603A-Full2, and related proposals (603B-Full2, 603C-Full, and 603D-Full2) (available at www.iodp.org/600/). Following ranking by the IODP Scientific Advisory Structure , the IODP Operations Task Force created the Nankai Trough Seismogenic Zone Experiment (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 operations in 2009, the IODP Operations Task Force scheduled two expeditions by D/V Chikyu: one with riser and riserless drilling for future borehole observatories (Expedition 319) and the other with riserless coring and wireline logging (Expedition 322). The highest priority components of IODP Expedition 322 were originally scheduled for drilling in 2007 by R/V JOIDES Resolution as part of NanTroSEIZE Stage 1, but operations were deferred several times for a variety of reasons. The supporting site survey data for Expedition 322, and the whole of NanTroSEIZE expeditions, are archived at the IODP Site Survey Databank.

Expedition 322 is currently scheduled to begin from Shingu, Japan, on 1 September 2009 and to return to Shingu on 10 October 2009. After a 4 day port call, a total of 36 days will be available for the drilling, coring, wireline logging, and downhole measurement operations described in this prospectus. At the time of publication, the ship schedule has not been finalized and may change. Refer to www.iodp.org/expeditions for more information and a current detailed schedule.
