Abstract:
Relative paleointensity (RPI; NRM/ARM) for the 20-50 mT demagnetization interval, magnetic susceptibility (κ) and magnetic grain size (κARM/κ) u-channel data, measured every centimetre between ~117 and 158 revised metres composite depth (rMCD) at IODP Site U1307, Eirik Drift, offshore southern Greenland. This data is provided against sample IDs, metres below seafloor (MBSF) depths, rMCD depths and age in thousands of years (ka). The time period covered by this dataset is ~2200 to 3200 ka, across the Plio-Pleistocene transition and the intensification of Northern Hemisphere glaciation.

Comment:
κ~ARM~/κ = It is derived from the ARM (anhysteretic remanent magnetisation) normalised by the direct current field value applied during its acquisition (the first **κ), then divided by the bulk magnetic susceptibility (the second κ).
