Notes: WSTP = Water Sampling Temperature Probe, DVTP = Davis-Villinger Temperature Probe. T = top of core, B = bottom of core. — = not applicable. * = average thermal conductivity. † = projected temperature at base of hole. The last line shows the temperature extrapolated to basement using linear fit in Figure F22 and the mean thermal conductivity computed from data plotted in Figure F20A.
