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 using parabolic projection. The last line shows the temperature extrapolated to the base of the hole using linear fit in Figure F27 and the mean thermal conductivity computed from data plotted in Figure F25.
