Outline of Final Research Achievements	I developed new supersensitive pH electrode for oceanographic continuous measurement. I investigated the structure of an ion-sensitive field-effect transistor (ISFET) as the pH electrode in order to avoid leak of current that affect stability of the pH electrode. A wafer of ISFET-pH electrode was fabricated at Kyushu Institute of Technology. The ISFET-pH electrode demonstrated excellent performance.
