In Hole 1096, the polarity sequence derived from the GHMT is quite simple (Fig. F7), with predominantly normal polarity from 375-408 meters below seafloor (mbsf) and predominantly reversed polarity <408 mbsf. The polarity of the remanent induction is in general agreement with the polarity from the correlation analyses. Both agree with the core paleomagnetic polarity.
The major difference is at the top of the logged section (367-375 mbsf), where both the GHMT methods indicate reversed polarity, whereas the core is normally magnetized. This is almost certainly because of proximity to the metal drill pipe and incomplete removal of its magnetic field, giving lower than expected remanent induction values.
The logged section of Hole 1095B represents a longer time interval than the section in Hole 1096C, so the polarity sequence is more complex (Fig. F8). The polarity of the remanent induction shows some agreement with the polarity from the correlation analyses. However, the latter is only about 50% complete because of the cutoff of R = 0.5 in the correlation analyses; it is strongly affected by depth mismatch between Bfr and Bfi and by the presence of spikes.
The polarity of the remanent induction mostly agrees with the core paleomagnetic polarity (Figs. F5, F8). As with Hole 1096C, there is some disagreement at the top of the logged section near the pipe. The shipboard interpretation of the magnetic polarity data is indicated in Figure F8 (Barker, Camerlenghi, Acton, et al., 1999). Other interpretations are possible, and the combined magneto- and biostratigraphy of Site 1095 are presented and discussed elsewhere in this volume.
