This $622,016 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports the collaborative development of a novel self-powered, multimodal pH, pressure, and temperature MEMS sensor system for marine carbon dioxide removal (MCDR) monitoring.
The project involves researchers from the University of North Texas, University of Michigan, and University of California San Diego working to design, fabricate, and test this innovative sensor array to provide uninterrupted, highly sensitive, and accurate pH measurements across ocean environments. Key objectives include developing a piezoelectric crystal-based pH sensor and an ocean wave energy converter to power the system, with integration and field testing to be conducted at UCSD's marine laboratory. If successful, this sensor technology could significantly enhance MCDR monitoring and have broader applications for ocean surveys, renewable energy, and environmental research.
A subaward to UCSD's Scripps Institution of Oceanography will support laboratory and field testing of the pH sensors developed under this grant, including calibration strategies and comparisons to established colorimetric techniques. The partnership between the lead institution and Scripps aims to prepare publications on the sensor testing process in the final year of the 3-year project period.
