Position: 31°48.12282’N, 139°0.82986’E
Water depth (m): 2080.2
Target drilling depth (mbsf): 2350
Approved maximum penetration (mbsf): 2100
Survey coverage: • Cruise KR08-04, Line IBM3-NE4, CDP 7266 (Figs. F9, F10, F13)
• Cruise KR08-04, Line IBM3-NW5, CDP 8113 (Figs. F9, F12, AF5, AF6, AF7)
Objective(s): Same as for proposed Site IBM-3C
Coring program: APC/XCB and RCB coring; casing as necessary
Wireline logging program: Standard downhole logging in one or two phases, depending on hole conditions and need for casing
Anticipated lithology: Volcaniclastic sediment and rock, perhaps with lava, perhaps crystalline igneous rock near bottom of hole
