For Full Proposals and APLs, a Site Figure (previously known as Site Summary Form 6) summarizing the supporting data that exist in the Site Survey Data Bank (SSDB), or that will in the near future be submitted to the SSDB, is required for each proposed drilling site. This required figure does not substitute for submitting data to the SSDB. Proponents must create the Site Figure as a single-page PDF document that contains the following four elements, depending on data availability:
- A label identifying the document as the Site Figure and indicating the site name
- A list of the file names of the relevant site-survey data that exist in the SSDB, i.e., the file names corresponding to the seismic data (images and SEG-Y) and navigation data presented on this form; for any displayed data that have not been submitted to the SSDB, the form should specify when the data will be submitted
- A clearly annotated map showing all relevant details around the proposed drilling site, including seafloor bathymetry, with labelled contours or a depth scale; the exact site location; track charts for the key seismic lines, annotated at regular intervals with the same horizontal unit (e.g., CDP, shot-point number, etc.) as the accompanying seismic profiles; and a distance scale if not apparent from the horizontal and vertical annotation. Any geographic coordinates must be in decimal degrees to the fourth decimal place if possible.
- Two profiles for each seismic line that crosses the proposed drilling site where appropriate. One profile should include an annotated vertical line showing the location (e.g., Site ABC-1A, CDP 4871) and penetration depth (or time using best depth-to-time conversion) of the proposed drilling site. This profile may also show an interpretation of the seismic data. The second profile should show the same image as the first profile, but without showing the drilling site or any interpretation. Each seismic profile should indicate the name and orientation (e.g., NW–SE) of the survey line, have well-annotated horizontal and vertical axes, including a horizontal scale bar (in km), and have sufficient resolution to show the relevant structure imaged by the data.
