Oftentimes one will see data in their cast that looks erroneous or out of spec, but reviewing the timeline of each cast and the events which transpired can explain these jumps. If you are starting your cast while your CTD is on deck then the time during which the unit...
Software & Data Processing
Why is my GPCTD losing samples near the end of the deployment?
Data is stored in a RAM page buffer, which is only written to FLASH when it is full. If the instrument is powered off, samples stored in the partially filled page buffer will be lost BUT the recorded sample number will still be the same. This means that when all...
My Shallow SeapHOx system has suddenly started reporting ‘NaN’ for Temperature, Conductivity, Salinity, Pressure, Oxygen, and pH external data, what is happening?
When the SeapHOx system loses connection with its 37 SMP-ODO CTD component, the system will report back the measured AND derived values related to that instrument as NAN. As part of this, it will also report its External pH as NaN as the salinity correction is missing...
Where can I find older versions of software that are not on the Sea-Bird Website?
Sea-Bird hosts an FTP (file transfer protocol) site for larger data transfers than are available by standard email. The instructions for gaining access to this FTP site can be provided by Sea-Bird Technical Support upon request. Software that is either no longer...
What is the spike found at the pump-out phase of my Hydrocycle’s sample reaction curve, and does it affect data quality?
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...
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...
