ACT has initiated a Performance Verification of commercially available in situ pH sensors for four reasons: 1) an increasing awareness of the need to monitor pH to assess ocean acidification and changes in the carbon chemistry speciation in coastal and estuarine ecosystems; 2) development of instrument packages to help in the maintenance and enforcement of water quality standards, 3) pH sensors and sensor packages are already available but vary in performance (see ACT workshop, In-situ measurement of dissolved inorganic carbon speciation in natural waters: pH, pCO2, TA and TCO2 , Honolulu Hawaii, February 2005); 4) verification testing of these instruments is feasible within a reasonable timeframe with existing ACT capabilities and funding. These test protocols delineate how ACT will evaluate the performance characteristics of in situ pH sensors through the collection and analysis of quality-assured environmental data. The goal of ACT’s verification program is to provide ind.....
