Hole summary

Report lists hole data: location, water depth, drilling, coring system, and core recovery.

Data File format

	Exp: expedition number
	Site: site number
	Hole: hole number
	Latitude: hole latitude
	Longitude: hole longitude
	Water depth (m): the distance from sea level to the seafloor.
	Penetration DSF (m): total penetration of all cored intervals and drilled intervals. Does not include ghost cores and wash cores.
	Cored interval (m): observed advancement of the drill string during coring. Does not include ghost cores, wash cores, or drilled intervals.
	Recovered length (m): core length measured on the catwalk (sum of section lengths as observed on the catwalk).
	Recovery (%): recovered length/cored interval * 100. Does not include ghost cores, wash cores, or drilled intervals.
	Drilled interval (m): drill string advanced without coring to deepen a hole.
	Drilled interval (no.): number of drill string advancements to deepen the hole (but not intended to recover core).
	Total cores (no.): number of cores that resulted in curated core material. Count does not include ghost cores, wash cores, or drilled intervals.
	APC cores (no.): number of cores collected with the advanced piston corer (H).
	HLAPC cores (no.): number of cores collected with the half-length advanced piston corer (F).
	XCB cores (no.): number of cores collected with the extended core barrel (X).
	RCB cores (no.): number of cores collected with the rotary core barrel (R).
	Other cores (no.): number of cores collected with other tools (e.g., ghost [G], wash [W], pressure [P]).
	Date started (UTC): date and time of beginning of activities on this hole as specified by the operations superintendent.
	Date finished (UTC): date and time of completion of activities on this hole as specified by the operations superintendent.
	Time on hole (days): date finished - date started. Presented as decimal days. May include gaps in operations.
	Comments: information provided by the operations superintendent.
