Bio-Optical Sensor Systems (BOSS)

Flexible platforms that expand sensor capabilities of profiling floats by providing multispectral radiometry, nitrate, scattering, beam attenuation, chlorophyll, and CDOM measurements to complement the temperature, salinity and oxygen measurements of the profiling float.

Sea-Bird Scientific offers a complete line of integrated instruments developed for deployment on profiling float arrays to observe biogeochemical parameters at global scales. The BOSS is a flexible package that expands the sensor capability of profiling floats by providing multispectral radiometry, scattering, beam attenuation, chlorophyll, and CDOM measurements to complement the standard suite of parameters that include temperature, salinity and oxygen.

The Bio-Optical Sensor System  manages data collection to minimize energy consumption. The instrument synchronizes multi-parameter sampling and logs the data including pressure, temperature, salinity, and dissolved oxygen data from the host profiling float with a common time reference to facilitate post processing.

The RemA and RemB series bolt-on sensors offer an integrated solution with the same parameter set, but without an onboard sensor controller. See for real time float data.

SatCon is a software utility for converting raw binary data, as logged by SatView, into readable ASCII text suitable for import by third party applications such as spreadsheets or databases. Data can be extracted in calibrated physical units or raw binary counts. SatCon can be operated interactively through a user friendly graphical interface, or in batch mode as a background process.

For minimum system requirements, installation instructions, and new features, please refer to the release notes in the SatCon User Manual.

Can Bio-Optical Sensor Systems operate alone?

The BOSS was specifically designed for bolt-on integration with an Argo profiling float. As such, the design and telemetry interfaces are not set up for stand alone or real-time profiling.

What should I use to lubricate bulkhead connectors?

We recommend keeping the connectors on your meter lubricated using a good quality silicone spray lubricant, such as 3M Silicone Spray or Loctite 8021 spray. These can be purchased at your local hardware store. Avoid silicone grease. It is messy and attracts contaminants.

Do not use WD-40. It will destroy connectors.
