Figure F10. Pore pressure measurements, Site U1319. Hydrostatic pressure calculated starting from the seafloor assuming a seawater density of 1.024 g/cm3. Bulk density data from shipboard moisture and density (MAD) measurements were integrated to calculate the overburden stress. The static pressure resulting from the water column above seafloor was subtracted from the pressure results. A. Porosity obtained from shipboard MAD measurement. B. Last recorded penetrometer pressure measurement (Table T2). C. In situ pore pressure estimated by 1/t extrapolation (Table T2). D. In situ pore pressure estimated by 1/√t extrapolation (Table T2). T2P = temperature/dual pressure probe.
