The Seasave and SBE Data Processing manuals document the derived variable formulas in an Appendix (Derived Parameter Formulas). The Help files for these programs also document the formulas..
FAQs
What formula does Sea-Bird software use to convert pressure data to depth?
The formulas are provided in Application Note 69: Conversion of Pressure to Depth.
In Sea-Bird software, is noon on January 1 Julian Day 0.5 or Julian Day 1.5?
In Seasoft-DOS version 4.249 and higher (March 2001 and later), January 1 is Julian Day 1. Therefore, noon on January 1 is Julian Day 1.5. Earlier versions of the software incorrectly defined January 1 as Julian Day 0, so noon on January 1 would appear as...
Can I edit my .dat data file to add some explanatory notes to the header?
Seasoft V2's Seasave (older software, replaced with Seasave V7 in 2007) created a .dat file from data acquired from the SBE 11plus V2 Deck Unit / SBE 9plus CTD. This also applies to earlier versions of the Deck Unit and CTD.Some text editing...
Can I edit my .hex data file to add some explanatory notes to the header?
Some text editing programs modify the file in ways that are not visible to the user (such as adding or removing carriage returns and line feeds), but that corrupt the format and prevent further processing by Seasoft. Therefore, we strongly recommend that you...
Why am I getting a class not registered error when running SBE Data Processing?
This error message typically means that some of the .dll files needed to run the software are installed incorrectly or have been corrupted. We recommend that you remove the software, and then reinstall the latest version.Note: Use the Windows' Add or Remove...
Why and how should I align data from a 911plus CTD?
The T-C Duct on a 911plus imposes a fixed delay (lag time) between the temperature measurement and the conductivity measurement reported in a given data scan. The delay is due to the time it takes for water to transit from the thermistor to the conductivity cell,...
What are the typical data processing steps recommended for each instrument?
Section 3: Typical Data Processing Sequences in the SBE Data Processing manual provides typical data processing sequences for our profiling CTDs, many moored CTDs, and thermosalinographs. Typical values for aligning, filtering, etc. are provided in the sections...
Where can I find formulas for calculating conductivity, temperature, pressure, and derived parameters such as salinity, sound velocity, density, depth, thermosteric anomaly, specific volume, potential temperature, etc.?
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...
Why am I having trouble connecting via the SBE 39plus or SBE 56 internal USB connector?
In July 2015, Sea-Bird released updated software to address intermittent connectivity issues where the host computer or SeatermV2 cannot recognize an instrument communicating via its internal USB connector. Field Service Bulletin 28 describes the problem and the...
