| Bottom water | 0 | APCT-12 | 1.88 | 0.005 | Consistent with predrilling site surveys |
| 3H | 24.1 | APCT-12 | 10.4 | 0.3 | Equilibrium temperature not used in later calculations |
| 5H | 43.1 | APCT-12 | 11.5 | 0.3 | Some tool motion |
| 9H | 82.2 | DVTP-1 | 20.1 | 0.1 | Considerable tool motion |
| 14H | 134.2 | DVTP-1 | ND | ND | Tool did not penetrate undisturbed formation |
| 17H | 247.4 | DVTP-1 | 58.2 | 0.3 | Considerable tool motion |
Notes: Depths have uncertainties of ±1.0 m. Tool 12 was used for all APCT tool deployments. The DVTP used probe tip 1, with thermistors F and G. Equilibrium temperatures were estimated by extrapolation of modeled tool response, as described in the text. Temperature uncertainty was estimated based on the least-squares best fit of the observational data to the modeled tool response, in addition to variability in estimated temperatures based on thermal conductivities of 1.0 to 1.5 W/m·K. APCT = advanced piston corer temperature tool, DVTP = Davis-Villinger Temperature Probe, ND = not determined.
