Operations summary

Expedition 345 occupied 16 holes in water depths ranging from 4675 to 4853 m. Seven holes were cored by rotary core barrel, recovering 55.2 m of gabbroic rock. An additional 19.8 m of core was recovered during hole-cleaning operations (“ghost cores”) (Table T1).

Two rotary core barrel holes were cored to >100 mbsf (111.8 mbsf in Hole U1415J and 107.9 mbsf in Hole U1415P). The other five rotary core barrel holes were cored to total depths ranging between 12.9 and 37.0 mbsf. The remaining holes occupied during Expedition 345 consisted of six jet-in tests and three failed attempts to establish reentry capability.
