Whole-core magnetic susceptibility (k) was measured on board the JOIDES Resolution during ODP Leg 178 using an automated multisensor track (Barker, Camerlenghi, Acton, et al., 1999). Subsamples were freeze-dried for magnetic granulometry analyses performed at the Institute for Rock Magnetism at the University of Minnesota. Hysteresis parameters were measured on a Princeton Measurements Corp. micro-vibrating sample magnetometer. Low-temperature (20 to 300 K) remanence and susceptibility measurements were made using a Quantum Design MPMS-XL susceptometer.
