Precision engineering is meaningless without proper calibration. Learn why calibration is an important aspect of Sea-Bird Scientific sensors.
SeaCATs, the CTD family consisting of the 16plus V2 and 19plus V2, were first developed in late 1985 back when Sea-Bird had barely evolved past a garage operation. When a customer requested a moored CTD – the first that Sea-Bird had ever built, Sea-Bird's team...
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.
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 +...
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...
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?
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.
Did you know that the sensors that power BGC-Argo are also in heavy use on shipboard and moored platforms? Learn about the analogous BGC sensors for deployment on moorings and vessels, and how your field crew can keep stride with ocean robots.
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.
Our training videos focus on useful information that we usually don’t cover in Sea-Bird University. Watch now to learn about topics ranging from troubleshooting water samplers to understanding solid-state pH sensors. View Our Video Collection Have a request for a new...
Upcoming Session - January 26th 2022, 3:00 pm PST: How to use, deploy, and maintain the new HydroCAT-EP V2 The new HydroCAT-EP V2 is now available. While it may look similar to its predecessor, we've built some new enhancements into this next iteration. Join us for a...
We're excited to announce Sea-Bird Scientific is attending the Oceanology International Conference this year from March 15 - 17, 2022. Due to the pandemic, our presence will be more limited than in previous years. We will be sharing our booth with one of our partners,...
The pH sensor on the new HydroCAT-EP V2 is accurate to 0.1 pH for 90 days, reducing the time you need to spend on maintenance. Beyond that, calibration is a simple process that users can do in the lab or field. Watch Cody Littleton, our primary HydroCAT-EP Service...
