The prototype sensor was deployed off shore of Honolulu, Hawaii for seven months on a moored buoy equipped with a Sea-Bird Electronics CTD and SAMI pH sensor unit. The buoy was deployed ~25m from an existing CO2 buoy, which allowed us to over constrain the carbonate system and thoroughly evaluate the performance of the prototype DIC sensor. In addition, 51 discrete bottle samples were collected throughout the seven month deployment and analyzed for DIC via coulometry. Results from this field test confirm that direct measurement of DIC is ~90% more accurate than estimates of DIC calculated from contemporaneous and collocated measurements of pH and CO2. The improved accuracy from directly measuring DIC gives rise to new opportunities for quantitative, autonomous carbon cycle studies. To test the performance of a novel moored autonomous DIC sensor prototype.
