Notes: DVTP = Davis-Villinger Temperature Probe. T = top of core, B = bottom of core. — = not applicable. * = average thermal conductivity, † = projected temperatures at seafloor and base of hole. The last line shows the temperature extrapolated to basement using linear fit in Figure F20 and the mean thermal conductivity computed from data plotted in Figure F18A.
