The NRM declinations, inclinations, and intensities of Sites 994, 995, and 997 are plotted against the sub-bottom depth in Figure 2. The declinations are plotted using the data before and after Tensor tool orientation, respectively. Before the orientation, the declinations are referred to core coordinates relative to the x-axis (positive-x) direction defined by the double-line fiducial mark in the center of the core liner on the working half of the cores (same as the standard ODP convention). After the orientation, the declinations are referred to geographic north.
The declinations (core coordinates and geographic coordinates) and inclinations obtained from the stable high-coercivity components of Type X and Y samples are plotted against the sub-bottom depth in Figure 3. The intensities of Type X and Y samples after the removal of the unstable low-coercivity components are also plotted in Figure 3.
The determined magnetic polarities of three sites are plotted against the sub-bottom depth in Figure 4, Figure 5, and Figure 6. There are several zones characterized by continuous normal or reversed polarities in each site. Normal and reversed polarity zones were identified where there are more than two successive samples of normal or reversed polarity. Undetermined polarity zones were defined where only a single sample of normal or reversed polarity was present. The figures also include nannofossil zones and datums obtained by Okada (Chap. 33, this volume).
Table 1 shows a list of the paleomagnetic data obtained by shore-based and on board measurements.
