Notes: NA = not available. Two uncorrected values are given for the measurement at 33.5 mbsf, corresponding to extrapolations using only data prior to the postinsertion disturbance and using the entire decay curve (except for the first few points). This illustrates the impact of disturbance during measurement. For the slope and intercept reported in the text and on Figure F41, only "good" and "excellent" data were used. The total uncertainty caused by uncertainties in calibration, extrapolation, and in the thermal conductivity value used for extrapolating to in situ conditions is estimated to be ±0.15°C for "excellent" data and ±0.25°C for "good" data. APCT = advanced piston corer temperature tool, APCT-3 = third-generation advanced piston corer temperature tool, DVTP = Davis-Villinger Temperature Probe.
