The next generation of low-cost, open-source oceanographic instruments is here! Meet the OpenCTD rev 2! | Southern Fried Science

"In 2013, Kersey Sturdivant and I embarked upon a quixotic quest to create an open-source CTD — the core tool of all oceanographic research that measures the baseline parameters of salinity, temperature, and depth. We weren’t engineers; neither of us had any formal training in electronics or sensing. And, full confession, we weren’t (and still aren’t) even oceanographers! What we were were post-doc marine ecologists working with tight budgets who saw a desperate need among our peers and colleagues for low-cost alternatives to insurmountably expensive equipment. And we had ties to the growing Maker and DIY electronics movements: Kersey through his work developing Wormcam and me through my involvement with OpenROV. 

We had no idea what we were getting ourselves into. ..."
