Updated Information Coming Soon!
Welcome to NanTroSEIZE!


The Nankai Trough Seismogenic Zone Experiment, or NanTroSEIZE , is a multi-disciplinary, integrated study of a subduction zone off the coast of Japan, with planned deep drilling of the plate boundary fault system as its centerpiece. Great subduction earthquakes are the world's most powerful seismic events and cause tsunamis such as the devastating Indian Ocean megathrust earthquake of Dec. 2004. The fundamental goal of the IODP NanTroSEIZE project is to drill, sample, and place monitoring instruments into the plate boundary fault system spanning the upper limit of the seismogenic zone at this subduction zone, which has produced massive earthquakes in the past.

Applications Accepted Now for Stage 1 Expeditions!



IODP Program Member Offices are currently accepting applications from interested scientists to staff a series of expeditions that make up Stage 1 of the NanTroSEIZE effort. Prospective applicants should review the Call for Applicants , NanTroSEIZE update , and the Stage 1 Scientific Prospectus .

NanTroSEIZE Stage 1 consists of five riserless drilling expeditions : two operated by the U.S. Implementing Organization (USIO) aboard a newly refurbished U.S. Scientific Ocean Drilling Vessel, and three operated by Japan's Center for Deep Earth Exploration (CDEX) aboard the R/V Chikyu .

See tentative stage 1 expedition schedule .

IMPORTANT STEPS for Applicants:


1) Read the NanTroSEIZE Stage 1 Prospectus and the Call for Applicants .

Consider the expedition(s) to which you would like to apply. You may be interested in more than one, and you are asked to rank your preference among the 5 planned Stage 1 expeditions. If you are unsure, please contact one or more of the co-Chief Scientists listed in the expedition table .
3) Visit your respective Program Member Office web site.
4) Fill out necessary form, and submit no later than Oct. 15, 2006.


Additional Information

For more in-depth information about the scientific goals and plans for NanTroSEIZE, please read the Complex Drilling Project proposal (IODP proposal 603-CDP) , and then the individual detailed proposals 603A-D .


NOTE: The original IODP proposals are organized by scientific theme, whereas the expedition "stages" are based on a scientific implementation strategy. Therefore, the five Stage 1 expeditions do not correspond to the five proposal documents on a one-for-one basis.
