University of Pittsburgh

University of Pittsburgh is developing buoy-based optical fiber sensors for measuring pH and carbon dioxide in seawater from the ocean’s surface to the seafloor. Using chemically selective and optically sensitive coatings, the proposed project would integrate a fiber optic sensing technology into low-cost commercial fibers used for marine buoy sensor systems. A reel-to-reel continuous manufacturing approach enables straightforward large-scale manufacturing. University of Pittsburgh’s approach would aid monitoring of nearshore marine carbon dioxide removal technologies, particularly those in need of continuous monitoring such as ecosystem recovery, alkalinity enhancement, and electrochemical solutions.
