**Figure F40.** Plot of pressure vs. depth, Site U1402. The hydrostatic pressure is calculated assuming a fluid density of 1.019 g/cm^{3} based on the pressure measurement at the mudline in the penetrometer. The overburden stress is calculated from integrating bulk density data from ODP Site 1073. Pressure plotted is the extrapolated tip pressure (see Fig. F39). The overpressure ratio (λ*) is equal to 0.2. Overpressure is 20% of the difference between the overburden and the hydrostatic pressure.
