For formulas for the calculation of conductivity, temperature, and pressure from the raw data, see the calibration sheets for your instrument (if you cannot find the calibration sheets, contact us with your instrument serial number at seabird@seabird.com> or +1 425-643-9866). For derived parameter formulas (salinity, sound velocity, density, etc.), see the Seasave and SBE Data Processing  manuals, which document these formulas in an Appendix. Additionally, the formulas are documented in the Help files for these programs.
