Figure F4. Variations in mean paleomagnetic inclination (25 mT) and initial NRM intensity (0 mT) for Section 2 of all cores from the uppermost 100 mcd at (A) Hole 1232A, (B) Hole 1233B, (C) Hole 1234A, and (D) Hole 1235B. Vertical dashed lines indicate cores in which advanced piston corer temperature (APCT) tool measurements were taken. In these experiments, the sediment sits below or at the seafloor in the steel (magnetic) core barrel for an extra ~10 min prior to recovery. In almost all cases, the cores that were obtained when the APCT tool was in use had a larger magnetic overprint, indicated by higher NRM intensities and inclinations that are farther from expected values (horizontal lines) even after demagnetization.
