•Hole B: APC/XCB to 300 mbsf
•Hole C: APC/XCB to 300 mbsf
•See “Drilling strategy” and Tables T1, T3
Wireline logging program: •If deeper drilling, logging with triple combo and FMS-sonic
•See “Downhole measurements strategy” and Tables T1, T3
Anticipated lithology: Carbonate ooze, hemipelagic clay, shallow-water carbonates
