History of the Argo CTD

History of the Argo CTD

Believe it or not, the first profiling floats couldn’t measure temperature and salinity. They solely traced ocean currents, totally ignorant of the sweet CTD data they were passing by. Adding a CTD changed the game. Learn more about the early beginnings of Argo, and how Sea-Bird’s first float CTD helped change the face of oceanography.

CTDs as Data Loggers

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 +...

The Argo Program in Numbers

The Argo Program in Numbers

In the last year of news, the dominant story has been a science topic: the coronavirus pandemic. And though most forms of Marine Science have little to do with the global response to COVID-19, its effects are felt in almost every aspect of our own scientific...

Q&A: Regular Spikes in Salinity

Q&A: Regular Spikes in Salinity

This salinity profile was from an arctic deployment in rough seas. At a certain point, we see regular salinity spikes of about ± .01 psu in the upcast data. Can you determine what caused this?

What is the STS Sensor?

What is the STS Sensor?

You never know what’s floating on the surface. That’s why Sea-Bird created the STS – to prevent the main Argo CTD from ingesting surface contaminants, but still obtain surface data. Learn how it helps extend deployments.

Video: Simulating an Inductive Mooring

Video: Simulating an Inductive Mooring

Conceptually, inductive moorings seem complex – communicating with 100 instruments through a single cable doesn’t exactly sound intuitive. But, in practice, the setup is surprisingly simple. Watch our latest video to see how easy it is to test and simulate an inductive modem mooring.

Moored CTD Troubleshooting Guide

Moored CTD Troubleshooting Guide

Deploying a moored CTD can be a game of trust. Nobody wants to return to their long-estranged CTD to find poor data quality. Of course, nobody wants to visit the middle of the ocean everyday either. Fortunately, we’ve created a basic troubleshooting guide for moored...
