| 1 | Regional map showing bathymetry, latitude and longitude, nearest land areas, and proposed site locations. |
| 2 | Track charts showing proposed sites and specific lines or line segments included for review. |
| 3 | Cross-tied seismic reflection lines of sufficient length and details to define closures. Seismic events should be legible to the depth of proposed penetrations. Seismic data may be presented as records or photographic prints. Suitable annotated negatives of prints must be sent to the ODP Site Survey Data Bank. The following annotations should be included on these lines (a) site number, location, and penetration depth; (b) traverse direction; (c) horizontal scale in kilometers; (d) vertical scale in seconds or meters; (e) course changes; (f) identification of important reflections; and (g) cross-line intersection points. |
| 4 | Sketches of major structural elements, sediment thicks and thins, and areas of distinctive reflection character. |
| 5 | Safety review check sheets. |
