Analog Sensor Integration Guide

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...

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: Temperature Mismatch

Q&A: Temperature Mismatch

Although they should match perfectly, the two sensors rarely reported the same temperature value throughout their deployment. Furthermore, the 16plusV2 appeared to stop logging, although the batteries still had life upon recovery. Can you identify the problem?

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.

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

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?...
