Integration of in-situ chemical sensors and ocean observing platforms

In the ocean observation, the chemical sensor which can measure objective parameter directly without needing chemical reagents is most suitable tool for the acquisition of consecutive data spatiotemporally. Development to widespread observation in the ocean by using several ocean observing platforms (ROV, AUV, ocean glider) installed with in-situ chemical sensor is demanded. I have been developing the in-situ pH/pCO
₂
/ORP sensor and radon sensor to perform high precision in-situ measurement of pH, pCO
₂
and radon (gamma ray) in the ocean. And I have been advancing downsizing and multichannelizing of the sensor electronic circuit board. Furthermore, I am developing the multi-sensor integrated control system which can connect and control both of developed sensors and commercial sensors for multicomponent simultaneous measurement.
