| Research Abstract |
In order to visualize pH distributions at sediment-water interface (SWI), two-dimensional pH sensor was developed. The sensor foil was fabricated alpha-Naphtholphthalein and Tetraphenylporphyrin immobilizing into a binder. Using with newly developed automatic image acquisition system and the sensor foil, semi-quantified pH image across SWI in an aquarium was obtained. For deep-sea application of the sensor, pH (or O_2) profiling system was developed. This system was evaluated at the cruise and the stability during the deployment was confirmed.
