About Us

Team SINDEN (Sensor INnovative Development for Environment in Nippon) was organized for registration to XPRIZE in 2014. In recent years, in-situ pH and pCO2 measurement in the ocean have attracted attention in relation to following global warming issues. 1: To monitor air-sea CO2 exchange and oceanic carbon cycles concerning global warming. 2: To verify an influence of ocean acidification due to global warming. 3: To assess an environmental impact of CCS (CO2 Capture and Storage) for mitigation of global warming. Therefore, continuous long-term monitoring and wide area observation at the ocean is necessary. Unfortunately, the shipboard measurement of pH and pCO2 in seawater is not convenient for this purpose. In-situ sensor is the most suitable for the long-term and continuous observations. We have been developing a non-glass type of in-situ pH sensor which uses an ion sensitive field effect transistor (ISFET) as the pH electrode and a chloride ion selective electrode (Cl-ISE) as the reference electrode from 1998. For the pCO2 sensor, the pH sensor was sealed with a gas permeable membrane filled with the inner solution.
