During Leg 185, igneous and sedimentary rocks were sawed as oriented cubes (~2.2 x ~2.2 x ~2.2 cm sides), and velocities were measured in three mutually perpendicular directions (x, y, and z). Standard moisture and density, including density and porosity, were measured on the smaller volume fragments adjacent to the cut cube (Fig. F1). One sample per section (every 1.5 m) was generally taken in cores from Hole 801C, making this one of the best sampled in situ crustal sections (Shipboard Scientific Party, 2000a). Six cube samples were taken of representative lithologies from Hole 1149B (Table T2). These sample cubes were then used for shore-based measurements of electrical resistivity and for X-ray CT imaging, which is presented in this data report.
During Leg 185, whole-round samples of representative sediments and rocks from Site 1149 were taken and immediately sealed in bags for subsequent shore-based permeability experiments (Hirono, this volume). X-ray CT measurements of these samples were obtained in an unsuccessful attempt to quantify the pore structures as a reference for permeability measurements (Hirono, this volume). Shore-based measurements of X-ray CT, velocity, and moisture and density on these samples are presented in Table T3.
