Summary: Compressional wave velocities were measured for sediments from the reference site for the Nankai subduction zone, obtained during Integrated Ocean Drilling Program Nankai Trough Seismogenic Experiment (NanTroSEIZE ) Expedition 333. The samples were cored at Sites C0011 and C0012. Five samples were tested from each site. Laboratory tests were conducted with controlled pore fluid pressure and confining pressure. We also measured porosity change during experiment s using the change in fluid volume. Porosity measured on board ranges from ∼0.50 to ∼0.69 for Site C0011 from ∼70 to ∼380 meters below seafloor (mbsf) and from ∼0.49 to ∼0.70 for Site C0012 from ∼60 to ∼165 mbsf. Compressional wave velocity ranges from ∼1510 to 1770 m/s at Site C0011 and ∼1510 to 1680 m/s at Site C0012, under hydrostatic fluid pressure conditions at the sampling depth.
