NanTroSEIZE overall scientific objectives

Tobin and Kinoshita (2006a, 2006b) provide the overall goals and plans of the NanTroSEIZE project as a whole. The reader is referred to those publications for details. Here, we briefly summarize the overall goals of NanTroSEIZE, focusing on Stage 3.

IODP will attempt to drill, sample, and instrument the seismogenic portion of a plate boundary fault, or megathrust, within the Nankai Trough subduction zone offshore the Kii Peninsula of Honshu Island (Fig. F1). This is a multistage, multiobjective project, now nearing completion of Stage 2. Stage 3 is the focus of the most ambitious objective: to access, sample, and instrument the Nankai plate interface within the seismogenic zone using riser drilling at Site C0002 (target depth = 7000 mbsf).
