The map shows predicted bathymetry and magnetic lineations. Site 1179 location relative to magnetic lineations in the northwest Pacific. Thick lines show magnetic lineations and fracture zones. Comparison of stratigraphic columns at Site 1179 and other DSDP and ODP boreholes in the northwest Pacific. The numbers at the top give site designations.
Biostratigraphic ages are along the left side of each column.
The distance from Site 1179 is shown at the bottom. The PAT was hung on the logging line by a bridle assembly consisting of wire cables, nylon straps, three glass ball floats, and a redundant acoustic release. Magnetic lineations in the vicinity of Site 1179. Thin, curved lines show magnetic anomalies, which are shaded where positive. Anomaly identifications are after Nakanishi et al.
