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 CSF-B (m): bottom edge of sample indexed to depth below seafloor on CSF-B scale.
	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.
