Magnetic remanence (spinner)

Magnetic remanence was measured on discrete samples by an Agico JR-6A spinner magnetometer, first as natural remanent magnetization (NRM) and then after demagnetization or remagnetization steps were performed on the samples (e.g., alternating field [AF] demagnetization, thermal demagnetization [TD], or isothermal remanent magnetization [IRM]).

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.
    Top offset (cm): top edge of the discrete sample measured relative to the top of a section or section half.
    Top depth CSF-A (m): location of the observation expressed relative to the top of a hole.
    Top depth [other] (m): location of the upper edge of the sample expressed relative to the top of the hole. The location is presented in a scale selected by the science party or the report user.
    Treatment type: type of treatment applied to the discrete specimen.
    Treatment value (mT or deg C or Agico code): value of the treatment. This may be field or temperature.
    Inclination (deg): inclination in specimen coordinates computed from JR6 magnetic moment data.
    Declination (deg): declination in specimen coordinates computed from JR6 magnetic moment data.
    Inclination geographic (deg): inclination in geographic coordinates computed from JR6 magnetic moment data with correction applied for user entered azimuth and dip.
    Declination geographic (deg): declination in geographic coordinates computed from JR6 magnetic moment data with correction applied for user entered azimuth and dip.
    Total intensity (A/m): total intensity as calculated by Rema6 software.
    Intensity X (A/m): mean intensity value for the x axis as calculated by the Rema6 software.
    Intensity Y (A/m): mean intensity value for the y axis as calculated by the Rema6 software.
    Intensity Z (A/m): mean intensity value for the z axis as calculated by the Rema6 software.
    Azimuth (deg): directional value entered by user at the time of measurement: horizontal angle.
    Dip (deg): directional value entered by user at time of measurement: vertical angle.
    Sample type: Indicates the type of sample measured, (e.g., cube).
    Remasoft TXT file: Remasoft data file.
    Remasoft JR6ODP file: Remasoft data file with IODP sample names.

    Instrument: abbreviation for the instrument used to measure discrete specimen magnetic remanence (JR6).
    Timestamp (UTC): point in time at which an observation or set of observations was uploaded to the data base.
    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.
