Measurements of magnetic properties were made on basalt samples recovered from Holes 597B and 597C. This paper describes the intensity and inclination of natural remanent magnetization (NRM), the intensity of anhysteretic remanent magnetization (ARM), the median demagnetizing field (MDF) for NRM and ARM, the initial susceptibility, the Koenigsberger ratio (Q). The mean inclinations (I) after alternating field demagnetization for Holes 597B and 597C are 45.4 ±7.1° and 45.0 ± 7.6°, respectively. These numeric quantities are greater than the calculated value of I = 34° expected at this site. A change of magnetic properties occurs at the depths of 100 and 120 m, respectively, which coincide with the boundaries between major petrological units.
