Build your very own CTD. Then kiss it and love it and call it George.

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!


The temperature fields test. Impressive.

Kim is a Senior Oceanographer at Sea-Bird Scientific. She received her Ph.D. in Physical Oceanography from the University of Washington in 2010. Her goal in life is to throw expensive s**t in the ocean. When not at sea, she has used observations from moored, satellite and land-based instruments to understand the pathways that wind and tidal energy take from large (internal tides) to small scales (turbulence). Her current mission is to make your oceanographic data be the best data it can be.

  1. I love that open source oceanography hardware is available to everyone
