| Outline of Final Research Achievements |
A measurement method of carbon dioxide in atmosphere and seawater at coral reef area by using solid electrolyte sensor has been examined as the simple, easy, and continuous carbon dioxide measurement is expected by using the sensor. The carbon dioxide sensor is composed of a solid electrolyte transducer with an auxiliary phase of a metal carbonate. So the water-resistance of the sensor element when using in seawater is one of important consideration. In this study, the carbon dioxide sensor elements were fabricated with several water-resistant solid electrolytes, and the sensing performances to carbon dioxide were investigated. Moreover, the plural and simultaneous measurements of dissolved carbon dioxide at different depths in a water tank by the sensor elements were investigated.
