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.
