RS-232 Sensor Integration Guide

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

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

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

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...

Q&A: Two Symptoms of the Same Problem

Q&A: Two Symptoms of the Same Problem

May 2020 Newsletter The data above show two major symptoms of the same problem occurring in different locations on a 19plusV2 profiling CTD. On the left, oxygen appears to drop below zero and is highly erratic during the downcast (light blue). However, once it hits a...

CTDs as Data Loggers

The acronym “CTD” might unofficially represent more than just conductivity, temperature, and depth. Since most CTDs include one or more auxiliary sensors, a given CTD package might technically be called a “CTDpHDOFLNTUTr” (CTD + pH + dissolved oxygen + fluorescence +...
