As the interest in marine or ocean-based carbon dioxide removal (mCDR) increases, so does the need for more spatially resolved measurement, reporting, and verification (MRV) of the CO₂ sequestered (and for understanding the impacts of these environmental manipulation experiments). Here the authors describe our efforts toward a low-cost CO₂ flux or ∆pCO₂ (the difference between air and water partial pressure of CO₂) monitoring system intended for use in distributed sensor arrays in coastal, estuarine, and blue carbon research and in mCDR approaches.
