Proposed Site NTS-1C

Priority: Primary: Chikyu Expedition 333 (NanTroSEIZE Stage 2: subduction inputs 2 and heat flow)
Position: 33°10.0482′N, 136°39.8454′E
Water depth (m): 2950
Target drilling depth (mbsf): 300
Approved maximum penetration (mbsf): 350
Survey coverage: Extensive survey data outlined in Proposal 603A-Full2:
• Primary line, CDEX 2006 3-D In-line 2269 at Cross-line 5094
• Crossing line, CDEX 2006 3-D Cross-line 5094 at In-line 2269
Objective: Collect core to characterize depositional dynamics of MTDs for use in analyzing sliding dynamics and tsunamigenic potential from sediments in the top 350 m
Drilling, coring, and downhole measurement program: HPCS/ESCS/EPCS coring, APCT-3
Anticipated lithology: 0–150 mbsf: slope apron hemipelagic sediments
150–190 mbsf: MTDs
190–300 mbsf: hemipelagic slope basin sediments intercalated with MTDs
