Position: 44.586056°N, 125.134881°W
Water Depth: 850 m
Sediment Thickness: ~7 km
Target Drilling Depth: 150 mbsf
Approved Maximum Penetration: 150 mbsf
Seismic Coverage: TTN112 3-D high-resolution seismic survey
Objectives: To sample reflection pair B/B' when they are above the BSR for comparison with proposed Site HR1a. Samples from this site will test the hypothesis that reflections B and B' represent carbonate formation along permeable horizons as part of a feedback process that further focuses fluid flow.
Drilling Program: APC to refusal, XCB to refusal. Possible use of PCS and/or HYACE.
Logging and Downhole Program: LWD, APC-temperature, DVTP, APC methane tools.
Nature of Rock Anticipated: Interlayered silts and clays, some authigenic carbonates possible.
