Position: 67°41.45´S, 072°13.08´E
Water Depth: 697 m
Sediment Thickness: 1700 m
Target Drilling Depth: ~600 mbsf
Approved Maximum Penetration: 698 mbsf
Seismic Coverage: BMR 33-57P2 SP 493, AGSO 186/1200 SP 3038
Objective: Sample the oldest glacial and youngest preglacial Cenozoic sediments in Prydz Bay.
Drilling Program: RCB Hole A to ~600 mbsf. Hole B will be drilled to ~100 mbsf using the logging-while-drilling-light (LWD-L) tool, which contains resistivity and natural gamma.
Logging Program: Hole A will use the triple combo, FMS-sonic, and GHMT tools; LWD-light in Hole B.
Nature of Rock Anticipated: Diamict, diatom ooze, sand, and mud. Possible sandstone and mudstone in preglacial section.
