The spike seen in the pump out phase is due to the commencement of flow and reagents/material that is outside the optical path initially but is swept through the optical path during flush out. The spike is accepted as normal behavior of the system and does not affect...
Software & Data Processing
When should I apply the tau correction in the post-processing of dissolved oxygen data?
Whether the tau correction is applied depends on where the system is being deployed.nnIf the system is to be used in shallow, coastal waters where large vertical gradients that change quickly are expected, the tau correction should be applied, as it accounts for the...
What are the CAPO4 and VAPO4 values reported by my HydroCycle-PO4?
CAPO4 is the phosphate concentration that the instrument reports as its measurement. CAPO4 is the calculated concentration of an ambient sample using the CAS slope, where CAS is the manufacturer's scale factor, which is provided by Sea-Bird. nnVAPO4 is used in a QC...
How can I copy the setup of my Sea-Bird software onto another computer?
A setup file is used by Seasave V7, and by each module in SBE Data Processing, to remember the way you had the program set up. You can save the file to a desired filename and location, and then use it when you run the software the next time, to ensure that the...
I am confused by all these software names. Which software does what?
Sea-Bird’s main software package is called Seasoft©. Seasoft V2 — Seasoft V2 is actually a suite of stand-alone programs. You can install the entire suite or just the desired program(s). Deployment Endurance Calculator — calculates deployment length for moored...
How can I identify and fix bubble spike failures in my Hydrocycle data?
First off, let’s see what a relatively good Raw Data Plot looks like. The different phases are the pre-flush phase (dark blue), the ambient baseline reading period (red), the sample reagent pump phase (green), the sample read/reaction phase (purple), and finally the...
What is the flag variable column that is added to the data file by SBE Data Processing’s Data Conversion or ASCII In module?
The flag variable column is added by Data Conversion (if you process data using Sea-Bird software) or ASCII In (if you are importing data that was generated using other software). The Loop Edit module sets the flag variable to bad for scans that show a...
What are SIP files?
Files that are delivered with Sea-Bird Scientific and third party equipment to describe the sensors data output and calibration coefficients come in two types. Calibration files or *.cal files and telemetry definition format files or *.tdf files. In some cases,...
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...
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...
