| Outline of Final Research Achievements |
Current "in-situ" observation technologies for deep-sea hydrothermal deposits are insufficient, despite these areas are remarkable such as rich deep-sea ecosystems, mineral development sources, etc.
In this study, two prototypes of the "in-situ" observation system have been developed and have been evaluated their performances; (1) a UV-LED light for fluorescent image observation of deep sea bed, (2) a violet laser spectrometer for fluorescent spectrum measurements of deep sea bed.
Additionally, the UV-LED light, (1), has been installed on a ROV and has been used for fluorescent observation successfully in the hydrothermal deposit in depth of roughly 1,000 m. In this "in-situ" observation, it is confirmed that each deep-sea species has inherent fluorescent colors by UV irradiation. It implies that auto-identification of deep-sea species by fluorescent colors is feasible in the future.
