Figure 68. Deployment of WSTP at 214.4 mbsf in Hole 897C. A. Observed temperature as a function of time. The temperature at the seafloor has been interpreted as 3.6° ± 0.1 °C, and the in-situ temperature was interpreted as 3.6° ± 0.1 °C. The portion of the temperature data used in the extrapolation is between arrows b and c. B. Observed temperature plotted vs. Bullard's "F" function (Bullard, 1954). The quality of the temperature extrapolation is reflected in the linearity of the plotted points.
