The typical LWD/measurement-while-drilling (MWD) bottom-hole assembly (BHA) used during Expedition 372 consisted of an 8½ inch tungsten carbide insert tricone bit, an 8¼ inch near-bit stabilizer/bit sub, various LWD/MWD tools, an 8¼ inch string stabilizer, a 6¾ inch float sub, a crossover sub, twelve 6¾ inch drill collars, a 6½ inch drilling jar, three 6¾ inch drill collars, and a crossover to 5 inch drill pipe. During Expedition 375, we conducted coring, wireline logging, and observatory operations.

The smaller bit can cut a semi-indurated core with less torque and fluid circulation than the main bit, potentially improving recovery. The XCB cutting shoe extends ~30.5 cm ahead of the main bit in soft sediments but is allowed to retract into the main bit when hard formations are encountered. XCB core barrels are 9.5 m long. The bottom-hole assembly (BHA) used for APC and XCB coring was composed of an 11 7 ⁄ 16 inch (~29.05 cm) drill bit, a bit sub, a seal bore drill collar, a landing saver sub, a modified top sub, a modified head sub, five 8¼ inch control length drill collars, a tapered drill collar, two stands of 5½ inch transition drill pipe, and a crossover sub to the drill pipe that extended to the surface. The RCB system is a rotary system designed to recover firm to hard sediments and igneous basement. The BHA, including the bit and outer core barrel, is rotated with the drill string while bearings allow the inner core barrel to remain stationary (Figure F3). RCB core barrels are 9.5 m long. The RCB BHA included a 9⅞ inch drill bit, a bit sub, an outer core barrel, a modified top sub, a modified head sub, a variable number of 8¼ inch control length drill collars, a tapered drill collar, two stands of 5½ inch drill pipe, and a crossover sub to the drill pipe that extended to the surface. Nonmagnetic core barrels were used in APC, HLAPC, and RCB deployments. APC cores were oriented with the Icefield MI-5 and FlexIT core orientation tools when coring conditions allowed. Formation temperature measurements were taken with the advanced piston corer temperature tool (APCT-3), and one deployment was attempted with the temperature dual-pressure (T2P) tool (see Downhole measurements). Information on recovered cores, drilled intervals, tool deployments, and related information are provided in the Operations section of each site chapter. Figure F1.

This information applies only to shipboard work described in the expedition reports section of the Expedition 359 Proceedings of the International Ocean Discovery Program volume. Methods used by investigators for shore-based analyses of Expedition 359 data will be described in separate individual publications. This introductory section provides an overview of operations, curatorial conventions, depth scale terminology, and general core handling and analyses. C. Betzler et al.. Expedition 359 methods IODP Proceedings 2 V o l u m e 3 5 9 APC system. Use of this new technology allowed for significantly greater continuous APC sampling depths to be attained than would have otherwise been possible. Nonmagnetic core barrels were used during all APC deployments to a pull force of ~40,000 lb. APC cores were oriented using the FlexIT tool (see Paleomagnetism). Formation temperature measurements were made with the advanced piston corer temperature tool (APCT-3). The APCT-3 was used to obtain temperature gradients and heat flow estimates (see Downhole measurements) for APC holes. A newly designed Motion Decoupled Hydraulic Delivery System (MDHDS) used to deploy the Sediment Temperature Tool (SET2) was tested at Sites U1467 and U1471. The MDHDS is designed to decouple the SET2 from the ship heave and thereby give more accurate readings because of reduced movement in sediment (see Operations in the Site U1467 and Site U1471 chapters [Betzler et al., 2017c). The XCB coring system was used to advance the hole when APC refusal occurred before the target depth was reached or when either the formation became too stiff for APC coring or hard substrate was encountered. The XCB system is a rotary system with a small cutting shoe (bit) that extends below the large APC/XCB bit. The smaller bit can cut a semi-indurated core with less torque and fluid circulation than the main bit, optimizing recovery. The XCB cutting shoe extends ~30.5 cm ahead of the main bit in soft sediment but retracts into the main bit when hard formations are encountered. XCB core barrels are 9.5 m long. The bottom-hole assembly (BHA) is the lowermost part of the drill string. The exact configuration of the BHA is reported in the Operations section of each site chapter. A typical APC/XCB BHA consisted of a drill bit (outer diameter = 11 7 ⁄ 16 inch), a bit sub, a seal bore drill collar, a landing saver sub, a modified top sub, a modified head sub, a nonmagnetic drill collar (for APC/XCB), a number of 8 inch (~20.32 cm) drill collars, a tapered drill collar, six joints (two stands) of 5½ inch (~13.97 cm) drill pipe, and one crossover sub. A lockable float valve was used when downhole logging was planned so that downhole logs could be collected through the bit. The RCB coring system was deployed when the formation became too hard for XCB coring. The RCB system is the most conventional rotary drilling system and was used during Expedition 359 to drill and core into lithified carbonate rocks. The RCB system requires a dedicated RCB BHA and a dedicated RCB drilling bit. The BHA used for RCB coring included a 9⅞ inch RCB drill bit, a mechanical bit release (if logging was considered), a modified head sub, an outer core barrel, a modified top sub, a modified head sub, and seven to ten control-length drill collars followed by a tapered drill collar to the two stands of 5½ inch drill pipe. Most cored intervals are ~9.7 m long, which is the length of a standard rotary core and approximately the length of a joint of drill pipe. In some cases, the drill string is drilled or "washed" ahead without recovering sediment to advance the drill bit to a target depth to resume core recovery. Such intervals are typically drilled using a center bit installed within the RCB bit. During RCB coring, half cores were sometimes collected to improve recovery. Cores recovered during Expedition 359 were extracted from the core barrel in 67 mm diameter plastic liners. These liners were carried from the rig floor to the core processing area on the catwalk outside the core laboratory, where they were split into ~1.5 m sections. The exact section length was noted and later entered into the database as "created length" using the SampleMaster application.

Sun et al. Expedition 367/368 methods IODP Proceedings 3 Volume 367/368 modified head sub, five 8¼ inch control length drill collars, a tapered drill collar, two stands of 5½ inch transition drill pipe, and a crossover sub to the drill pipe that extends to the surface. The RCB system is a rotary system designed to recover firm to hard sediments and igneous basement. The BHA, including the bit and outer core barrel, is rotated with the drill string while bearings allow the inner core barrel to remain stationary (Figure F2C). A typical RCB BHA includes a 9⅞ inch drill bit, a bit sub, an outer core barrel, a modified top sub, a modified head sub, a variable number of 8¼ inch control length drill collars, a tapered drill collar, two stands of 5½ inch drill pipe, and a crossover sub to the drill pipe that extends to the surface. Cores collected with the RCB system are denoted by the letter "R. " Nonmagnetic core barrels were used for all APC, HLAPC, and RCB deployments. APC cores were oriented with the Icefield MI-5 core orientation tool when coring conditions allowed. Formation temperature measurements were taken with the advanced piston corer temperature tool (APCT-3; see Downhole measurements). Information on recovered cores, drilled intervals, downhole tool deployments, and related information are provided in the Operations, Paleomagnetism, and Downhole measurements sections of each site chapter.
