Subsurface automated samplers (SAS) for ocean acidification research
by Ian C Enochs, Nathan Formel, Lauren Shea, Leah Chomiak, Alan Piggot, Amanda Kirkland, Derek Manzello

Florida-based scientists have developed a low-cost subsurface automated sampler suitable for the collection of water for carbonate chemistry analysis. The paper describes the design, use, and performance of the SAS and provides detailed how-to instructions to build your own. The ultimate goal is to lower the cost of ocean acidification monitoring and facilitate research while encouraging application-specific customization.
