Proposed Site U1301B

Priority: Primary
Position: 47°45.228′N, 127°45.827′W
Water depth (m): 2611
Target drilling depth (mbsf): Not applicable; reoccupy existing borehole; no new penetration
Approved maximum penetration (mbsf): Not applicable; reoccupy existing borehole; no new penetration
Survey coverage: GeoB00-466: CDP 556. Hole U1301B is offset 35 m on a heading ~N13°E from Hole U1301A. This offset is oblique to the strike of seismic Line GeoB00-466. The along-line distance is roughly equivalent to one shotpoint, as listed. (Track Map Fig. F2, Seismic Profile Fig. F4)
Objective: Long-term monitoring of pressure, geochemistry, and microbiology
Drilling and Logging program: Recover and replace instrument string
See "Operations plan/drilling strategy" and Table T3
Nature of rock anticipated: Not applicable; reoccupy existing borehole; no new penetration
