Q&A: Identifying Data Types
Can you correctly label the 4 plots? Hint: this area is subject to periods of eutrophication during the late summer/early fall.
Analog Sensor Integration Guide
From bottom contact triggers to transmissometers, oceanographic sensor options are vast and diverse, and choosing the right combination of sensors can significantly augment a CTD’s measurement capabilities. Although getting disparate technologies to talk to one...
Q&A: Negative Oxygen Values
Dissolved oxygen should not be negative. Can you determine the error that created the unusual oxygen profile above?
RS-232 Sensor Integration Guide
Unlike analog auxiliary sensors, instruments that output serial RS-232 data are more challenging to integrate with Sea-Bird Scientific CTDs. Despite RS-232 being a standard communication protocol, most instruments have a unique data output format and command set. As...
Tech Tip: Cable Search
Consider this hypothetical situation: you find a loose cable with a 6-pin connector and a 4-pin connector - exactly what you need to connect an oxygen sensor to your CTD. However, just because the cable ends fit on the instrument connectors, you still don’t know if...
Q&A: Diagnose This Profile
The data shows conductivity from a 19plus deployed in a shallow estuarine river. The red line shows the CTD downcast and the green line shows the upcast. While the upcast data show the expected shape for a CTD profile (low conductivity at the surface, rising conductivity as the CTD descends), the downcast shows an unusual shape in until about 2.6 meters depth, where conductivity appears to suddenly correct itself.
Discontinued – WQM and WQMX
July 2020 Newsletter Over the past 12 years, the WQM and WQMX have been integral to accelerating the understanding of natural waters. This instrument family was the first collaboration between WET Labs and Sea-Bird Electronics before our companies became fully...
Tech Tip: Julian Days Format
Tech Tip: Julian Days Format “Julian Days” is a numerical timestamp format, calculated by Sea-Bird Scientific CTDs as the number of the days since Jan 1 of that year (e.g., noon on Feb 3 = 34.5). While this format is useful, it is usually more convenient to display...
Q&A: Diagnosing Salinity Spikes
Q&A: Diagnosing Salinity Spikes The figure above shows a time series of salinity from a moored CTD. For most of the deployment, salinity showed frequent downward spikes, dropping from an expected range of 18-26 psu to near zero. Can you determine the cause?...
Product Update | AC-9 Discontinuation and Service Timelines
In 2011, the Sea-Bird Scientific AC-9 (formerly WETLabs AC-9) was discontinued and replaced by the Sea-Bird Scientific AC-S. We recognize that many users rely on Sea-Bird Scientific products for several years, so we have continued to offer Best Effort Service for the...

Remembering Art Pederson
Art Pedersen, founder of Sea-Bird Electronics, passed away on October 8th, 2021. His designs are firmly cemented into Sea-Bird’s CTDs, and he leaves behind profound impacts on how scientists make measurements in the ocean. Dr. Norge Larson, former president of...
SeaFET 0.6 Trade-in Offer
Sea-Bird Scientific introduced the SeaFET V2 and SeapHOx V2 in 2018. These products brought several improvements to our line of ISFET pH products, including higher reliability and dramatically improved calibration quality. The V2 models are the current offering and...
Flushing and Storing pH Sensors on the HydroCAT-EP V2
The HydroCAT-EP V2's new pH sensor design makes it safer and easier than ever to swap sensors in the field. A new flushing port ensures that corrosive seawater stays far away from the electronics, while a new mechanical design creates a snug fit to withstand the...
