The SBE9/11+ system does not have the capability to support any instrumentation data or signals via its sea cable that are not directly connected to the SBE9+ CTD and associated carousels.
There is a hardware upgrade on the 9/11+ system that provides a serial RS-232 data uplink. This is a relatively constrained feature on the 9/11+ system, that allows a serial RS-232 data stream to be passed up the sea cable and saved as a separate data file.
NOTE: This upgrade is installed in the 9/11+ at the factory and operates at 9600 baud, requiring
that the 9/11+ be configured/operating at this same baud rate.
None of this is compatible with a video signal to be integrated into this system. Additional hardware components inline with the sea cable that are not supplied by Sea-Bird Scientific would be required. This custom application is not currently supported.

Sea-bird Scientific no longer directly sells and ships Triton-X. Since January 4th,2021 Triton-X has been banned in the EU due to a key ingredient being a known endocrine disrupter. TERGITOL is a non-ionic surfactant which can be used as a substitute for Triton-X. It can be purchased at Sigma Aldrich. The surfactant is supplied in 100% strength and will need to be diluted. If neither surfactant is available, vinegar or a diluted bleach solution can be used as a substitute.
- Conductivity sensors — TERGITOL is typically diluted to 0.1% strength (by 1000) for rinsing and for rewetting the conductivity cell just before deployment, and to 1% to 2% strength (by 50 to 100) for cleaning the conductivity cell. Refer to Application Note 2D: Instructions for Care and Cleaning of Conductivity Cells and to the maintenance section in the instrument manual for details.
- SBE 43 (membrane-type) Dissolved Oxygen sensors — TERGITOL is typically diluted to 0.1% strength (by 1000) for rinsing, and to 1% (by 100) for cleaning. Prolonged exposure of the sensor membrane to Triton causes the sensor’s calibration to drift. Do not place Triton directly on the membrane. See Application Note 64: SBE 43 Dissolved Oxygen Sensor – Background Information, Deployment Recommendations, and Cleaning and Storage for details.
- SBE 63 Optical Dissolved Oxygen sensors — TERGITOL is typically diluted to 0.1% strength (by 1000) for rinsing, and to 1% (by 100) for cleaning. Do not place TERGITOL directly on the optical window. See the SBE 63 manual for details.
The most common telemetry system utilized is a FreeWave radio system. Transmission times for the science data are typically 20-30 seconds through the FreeWave modem when the receiver is within 3 km of the profiler.
Other telemetry systems include a broadband cellular and Iridium modems.
This is a safety feature of the instrument, whereby the lamp is turned off when its temperature reaches 35°C (95°F) to prevent damage from overheating. The SUNA continues to output dark frames while monitoring the temperature, and will restart the lamp once it has dropped back below 35°C. If extended in-lab use is required, immersing the SUNA in a cool bath can prevent this behavior.
