Notes: APC = advanced piston corer, XCB = extended core barrel. Reason for APC termination: A1 = Pollution Prevention and Safety Panel approved depth is reached, A2 = mission accomplished, B1 = incomplete stroke is indicated, B2 = excessive pull out force >100 klb, C = mechanical. * = average from holes with APC refusal.
