Notes: Transit time is at 10.5 kt. Coring depths and times for proposed Sites SPG-1A, SPG-4A, and SPG-6A assume 100 m of basement penetration. Coring time estimates assume four advanced piston corer (APC) holes for the first three primary sites. The remaining four sites are scheduled for four APC holes, but an extra hole will be piston cored if time becomes available in the schedule. Any additional time will be used to deepen the basement holes. Coring time estimates also include one complete pipe trip per site (down and back) for the APC/sediment only sites and, at basement sites, two complete pipe trips per site (down and back), one for the APC holes and one for the rotary core barrel (RCB) hole. Logging time estimates assume two complete logging runs per site at ~12 h/trip for sites selected for logging. Proposed Sites SPG-3A and SPG-7A are alternate sites for basement objectives. Proposed Sites SPG-5A and SPG-9A are alternate sites for sediment objectives. Proposed Site SPG-8 is not included in the drilling plan because it was not surveyed during Cruise Knox-02RR.
