Results

Table T1 summarizes the effective stress and estimated porosity and permeability at each consolidation step. Permeability is plotted as a function of porosity on Figure F3, with samples noted that were observed to contain primarily sand or ash. Permeabilities where the standard deviation exceeded 10% of the value are italicized in Table T1 and are not plotted on Figure F3. For comparison, Figure F3 also shows the permeability-porosity relationship developed by Skarbek and Saffer (2009) for hemipelagic mud of the Shikoku Basin facies sediments from Ocean Drilling Program (ODP) Sites 1173 and 1174 on the Muroto transect (log(k) = –20.45 + 6.93n). With the exception of three samples, two of which were noted to contain sand-sized material and one which was slope sediments of Site C0018, permeabilities generally fall near or below that indicated by the Skarbek and Saffer (2009) relationship. Measured vertical permeabilities vary from ~1.3 × 10^–19 to ~2.8 × 10^–16 m².
