Priority: Primary

Position: 44.570386°N, 125.147657°W

Water Depth: 780 m

Sediment Thickness: ~7 km

Target Drilling Depth: 60 mbsf

Approved Maximum Penetration: 60 mbsf

Seismic Coverage: TTN112 3-D high-resolution seismic survey

Objectives: To sample the high-amplitude chaotic reflectivity that is associated with the massive hydrates at the seafloor. Samples from this site will test the hypothesis that this reflective character is the signature of a zone of abundant massive hydrate.

Drilling Program: APC to refusal, XCB to refusal. At least two holes. Use of PCS and/or HYACE.

Logging and Downhole Program: LWD, triple combo, APC-temperature, DVTP, APC methane tools.

Nature of Rock Anticipated: Silts and clays interlayered with massive hydrate, some authigenic carbonates possible.
