Magnetic remanence (SRM-longcore)

Magnetic remanence was measured on section halves (and rarely on whole-round sections) using a 2G Enterprises 760R cryogenic magnetometer, first as natural remanent magnetization (NRM) and then after demagnetization steps were performed on the samples by alternating field (AF) demagnetizer coils mounted in-line within the instrument.

Data File format

    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.
    Treatment type: refers to type of remanent magnetization measured, such as NRM, ARM, and IRM.
    Treatment value: level of treatment that was applied to the sample being measured.
    Inclination background & drift corrected (deg): inclination computed with background and drift correction.
    Declination background & drift corrected (deg): declination computed with background and drift correction.
    Intensity background & drift corrected (A/m): intensity computed with background and drift correction.
    Inclination raw (deg): inclination computed from magnetic moment data.
    Declination raw (deg) declination computed from magnetic moment data.
    Intensity raw (A/m): intensity computed from magnetic moment data.
    Magnetic moment x (Am^2): magnetic moment raw data from X SQUID axis, with sign corrected to match IODP orientation conventions
    Magnetic moment y (Am^2): magnetic moment raw data from Y SQUID axis, with sign corrected to match IODP orientation conventions
    Magnetic moment z (Am^2): magnetic moment raw data from Z SQUID axis, with sign corrected to match IODP orientation conventions
    Sample orientation: orientation of section measured (e.g., archive or working).
    Raw data filename: SRM raw data file.
    SRM background filename: SRM background with tray data file.
    Configuration filename: SRM instrument configuration file.
    Instrument: abbreviation for the magnetometer used to make this measurement (SRM).
    Timestamp (UTC): time file was uploaded, which is typically a few minutes to hours after data were acquired.
    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.
