Position: 44.588421°N, 125.107920°W
Water Depth: 970 m
Sediment Thickness: ~7 km
Target Drilling Depth: 260 mbsf
Approved Maximum Penetration: 260 mbsf
Seismic Coverage: TTN112 3-D high-resolution seismic survey
Objectives: To sample a negative polarity reflection beneath the BSR that was originally interpreted to be a "double BSR" of unknown origin but that appears in the 3-D data to be an unconformity related to high-amplitude reflections B and B', which are targeted by proposed Sites HR1a and HR1b.
Drilling Program: APC to refusal, XCB to refusal, RCB as necessary to reach target depth. Two holes. Possible use of PCS and/or HYACE.
Logging and Downhole Program: LWD, triple combo, APC-temperature, DVTP, APC methane tools.
Nature of Rock Anticipated: Interlayered silts and clays, some authigenic carbonates possible, highly deformed accretionary complex sediments.
