Validation of a Novel Solid State Alkalinity Sensor for Marine Carbon Dioxide Removal

Accurately measuring ocean alkalinity is essential for understanding the ocean’s role in the carbon cycle and ocean acidification, both of which are critical for addressing climate change. However, traditional sampling and laboratory analysis is labor-intensive, costly, and limited in coverage. This project will assess novel alkalinity sensor technologies that have the potential to transform marine carbonate system monitoring — by enabling real-time, high-resolution, automated measurements — and compare them with high-precision academic research methods. The project goal is to provide a scalable solution for ocean carbon cycling and acidification studies, as well as marine carbon dioxide removal. Accurate measurement, monitoring, reporting, and verification that is financially operable at scale will improve the credibility of voluntary carbon markets, ensuring that carbon removal claims are robust.
