P-wave velocity bayonet (section) report P-wave velocity data were measured on undisturbed section halves using pairs of piezoelectric transducers mounted in bayonets that are inserted into soft sediment along the IODP-JRSO-defined y-axis and/or z-axis. Report includes P-wave velocity in y and/or z direction, bayonet separation, traveltime between transducers, and first arrival picks. Exp: expedition number Site: site number Hole: hole number Core: core number Type: type indicates the coring tool used to recover the core (typical types are F, H, R, X). Sect: section number A/W: archive (A) or working (W) section half. Offset (cm): position of the observation made, measured relative to the top of the section. Depth CSF-A (m): location of the observation expressed relative to the top of a hole. Depth [other] (m): location of the observation expressed relative to the top of a hole. The location is presented in a scale selected by the science party or the report user. P-wave velocity y (m/s): velocity of pressure wave through sample in the y axis (computer pick). P-wave velocity z (m/s): velocity of pressure wave through sample in the z axis (computer pick). Transducer separation (mm): distance between the transducers on the bayonet. Sonic traveltime (µs): traveltime of the sonic wave from transducer to transducer through the sample (computer pick). P-wave velocity y [manual] (m/s): velocity of P-wave through sample in the y axis, calculated using the manually picked traveltime. P-wave velocity z [manual] (m/s): velocity of P-wave through sample in the z axis, calculated using the manually picked traveltime. Sonic traveltime [manual] (µs): manually picked traveltime of the sonic wave from transducer to transducer through the sample. Transducer signal file: file containing the raw P-wave signal. Configuration filename: P-wave bayonet instrument configuration file. Instrument: abbreviation or mnemonic for the P-wave sensing device used to make this observation. Instrument group: abbreviation or mnemonic for the data collection device used to acquire this observation. Timestamp (UTC): date and time the observation was made. Text ID: automatically generated unique database identifier for a sample, visible on printed labels. Test No: unique number associated with the instrument measurement steps that produced these data. Sample comments: observations recorded about the sample itself. Test comments: observations about a measurement or the measurement process; some measurement observations may be under Result comments. Result comments: observations about a measurement or the measurement process; some measurement observations may be under Test Comments.
