| Outline of Final Research Achievements |
In the present study, the electrical components that previously required a pressure-resistant container were also placed in an oil-immersed container, and the pressure-resistant container was eliminated. We have constructed an observation system that is lightweight and contributes to clarifying material circulation in the entire ocean.
Although it is possible to use a resin mold to connect the sensor-sensitive part and the electrical component part, it was found that a pressure-resistant underwater connector is preferable in consideration of ease of removal, so the sensor policy was implemented separately. As a result of a pressure resistance test, it operated well. As a result of conducting the actual sea area test in the sea hills off Ito, it worked well and succeeded in measuring the underwater data.

| Academic Significance and Societal Importance of the Research Achievements |
本研究において、油漬けや真空パックによる被圧化が進めば、耐圧容器無しでの簡便な取扱が可能なセンサ開発に道筋が立つ。また、耐圧容器レス化により、pHや溶存酸素といった水中化学センサの小型化が進み、また安価に提供出来るようになる。これらのセンサを自動昇降ブイや小型の水中HDビデオロボットに搭載可能となることで、海洋観測における網羅的な化学センシングが可能となるであろう。この点が本研究の特色であり、独創的な点である。
