Figure 48. WSTP deployment at 122.4 mbsf in Hole 900A. A. Observed temperature as a function of time. The bottom-water temperature is interpreted to be 3.8 ± 0.1 °C, and the in-situ temperature is interpreted to be 10.2 ± 0.1 °C. The insertion time used for curve fitting is indicated by arrow a. The portion of the temperature data used in the extrapolation is between arrows b and c. B. Observed temperature plotted against Bullard's "F" function (Bullard, 1954). The quality of the temperature extrapolation is reflected in the linearity of the plotted data.
