Abstract
Quantifying oceanic CO2 uptake and ocean acidification and understanding their impact on global climate and ocean ecology are key goals of NOAA’s climate change research programs. NOAA’s request for Development of a long-term Lagrangian pH and pCO2 drifter (SBIR Subtopic 8.3.1C) aims to address these goals by developing technology that measures both pCO2 and pH that can be widely deployed in the world’s oceans. Sunburst Sensors proposes to develop an innovative, reasonably priced pH and pCO2 measurement system for oceanic surface drifters. Indicatorbased opto-fluidic sensors have been designed and fabricated using microfluidic manufacturing techniques. Success in Phase I led to a prototype sensor that will be evaluated and refined. Alternative optical components will be tested and a final opto-fluidic cell will be designed. A modified circuit board, firmware and client software will be developed to control the system and interact with the drifter’s satellite modem and strain gauge. The system will then be packaged to fit into a Global Drifter Program style drifter. The total system will be pier tested for two weeks to evaluate performance and ultimately deployed in the ocean from a research vessel, with data collected for the sensor lifetime (~1 year) or until it ceases operation.
