Notes: Measurements for which two core numbers are given (e.g., Section 204-1251B-18P-19) were made with the DVTPP between these two cores. APCT measurements were made at the core catcher of the core listed. No thermal conductivity values are given for the DVTPP data because no extrapolation was done. For APCT measurements, thermal conductivity represents the average of the nine measurements taken in the adjacent core. A star in the last column indicates that this measurement was not used in the calculation of subsurface thermal gradient. ID = identification.
