Figure 1. Geographic-information-system interface to Deep Sea Drilling Project and Ocean Drilling Program core hole data stored in the Neptune database
Figure 2. Age-depth plot developed from Neptune sample occurrence data for Hole 41-366A. F—foraminifera; N—nannoplankton; R— radiolarians; and D—diatoms; mbsf—meters below seafloor
Figure 3. Age-depth plot shown while user is moving a line of correlation (LOC) control point. Age-Depth Plot enforces a model representing nondecreasing age with increasing depth by limiting movement to the region bounded by the gray rectangle. Short labels for events are also displayed. See Figure 2 for definitions
Figure 4. Line of correlation (LOC) control point data table. User has associated the control point (at 24 Ma, 270 m below seafloor [mbsf]) with a datum at that location and has added a comment on the selection
