Observatory Data Portal
Welcome to the NanTroSEIZE pore pressure observatory data portal! This portal provides access to interactively visualize and download pore pressure data from IODP Site C0002, located in the Nankai Trough, above the active seismogenic subduction plate boundary offshore SW Honshu, Japan. Data are available from two pressure sensors monitoring the subsurface rock formations: one within the uppermost accretionary prism (937-980 meters below seafloor; mbsf), one in the overlying Kumano Basin fill sediments (757-780 mbsf). In addition, pore pressures are available from a seafloor reference sensor, and a subsurface sensor that is cemented in the hole with a tiltmeter, strainmeter, and seismometer (not in hydraulic communication with the formation).
