| # | Name | Short Name | Unit | Principal Investigator | Method/Device | Comment |
|---|---|---|---|---|---|---|
| 1 | Sample code/label | Sample label | Boyce, Robert E | DSDP/ODP/IODP sample designation | ||
| 2 | DEPTH, sediment/rock | Depth sed | m | Geocode – mbsf | ||
| 3 | Sonic velocity | Sonic vel | km/s | Boyce, Robert E | Hamilton frame velocimeter, Boyce (1976) | Compressional, vertical beds |
| 4 | Temperature, technical | T tech | °C | Boyce, Robert E | Compressional sound velocity | |
| 5 | Hydrostatic pressure | Sigma H | kPa | Boyce, Robert E | see reference(s) | Hydrostatic pressure = depth below sea level x 1.035 g/cm**3. Original unit kg/cm**2, multiplied by 98.0665 |
| 6 | Temperature, in rock/sediment | t | °C | Boyce, Robert E | In situ, assumes 40 deg C/1000 m temperature gradient for simplicity and seafloor temperature of 2.9 deg C | |
| 7 | Flow velocity, water | Vel water | m/s | Boyce, Robert E | see reference(s) | In situ, seawater. Uses Navy SP58 with Table 5. Linearly extrapolated from 35 deg C to 48 deg C and assumes 35 ppt |
| 8 | Sonic velocity | Sonic vel | km/s | Boyce, Robert E | Hamilton frame velocimeter, Boyce (1976) | Vertical, corrected for hydrostatic pressure and temperature |
| 9 | Sonic velocity | Sonic vel | km/s | Boyce, Robert E | Hamilton frame velocimeter, Boyce (1976) | Velocity corrected for hydrostatic pressure, temperature, and porosity rebound and not changes in rigidity caused by overburden pressure |
