This project, funded under NOPP Topic 3A Sensors for Measurement of Biological, Bio-Optical or Chemical Properties of the Ocean, uses NOPPNSF funding to commercialize an autonomous, in situ indicator-based pH sensor that was developed in the PIs lab. The long-term goal of the project is to make more autonomous chemical and biological sensors available to the oceanographic research community. These autonomous sensors will enable researchers able to more effectively study processes such as natural CO2 sequestration and ocean acidification. The objective is to commercialize the autonomous pH sensor, SAMI-pH, through Sunburst Sensors, LLC. Studies conducted in the PIs laboratory found that the original SAMI-pH design had excellent precision, accuracy, and long-term stability. However, this design was complex with high power requirements and primitive software. The goal of this project is to improve upon the strengths of the existing sensor, while making the instrument more commercially attractive.
