IODP Nankai Trough Seismogenic Zone Experiment
Stage 2 Expedition 322 "Subduction Inputs" |
 |
 |
OVERVIEW |
| Expedition Number |
322 |
| Objective |
Characterization of composition, architecture, and state of pre-subduction sediments transported to the seismigenic zone. |
| Location |
Nankai Trough, Kumano-nada, Offshore Kii peninsula, Japan |
| Period |
From Sep.1 2009 to Oct.10
(Port Call) From Sep.1 2009 to Sep.4
(At Sea) From Sep.5 2009 to Oct.10 |
| Drilling Vessel |
Chikyu |
| This expedition will investigate input material entering the seismogenic zone, by characterizing the composition, architecture, and state of sediments that will be transported by the subduction system offshore the Kii Peninsula, Japan. NT1-07 will drill up to 1200 meters below the seafloor through turbidite-rich strata overlying smooth oceanic basement. The data will provide key constraints on the initial conditions for the "subduction conveyor", which transports the incoming sediments and ocean crust to higher P-T conditions and hypothesized to be an important factor for drive the onset of seismogenic fault behavior. |
