OMG OMG OMG OMG, Andrew Thaler, Kersey Sturdivant and Russell Neches over at Oceanography for everyone have just published a Build Guide for the OpenCTD, the CTD you can build at home.
In case you didn’t know, a CTD is the tool that enables us to calculate the temperature, salinity and density of seawater. They are also very, very expensive. This is why the OpenCTD is so amazing. Now for a fraction of the cost, you can build your own if you need/want to. All the code and the instructions can be found on their GitHub site. And you can also build an adorable little niskin bottle for your ROV. WOOT for low cost, open source ocean observing!
Share the post "Build your very own CTD. Then kiss it and love it and call it George."
I love that open source oceanography hardware is available to everyone
I love the title of this article. Well done!
