| Outline of Final Research Achievements |
In recent years, there has been concern about the deterioration of the marine (fishing) environment, such as coral bleaching and the loss of seaweed beds due to rocky shore scorching. It is important to quickly assess changes in the distribution, abundance and diversity of marine organisms due to environmental change. Therefore, there is a need for the development of environmental measurement technology (equipment) that is simple, inexpensive and can quickly assess environmental changes and their effects.
In this study, a fluorescence imaging device was developed that can capture the fluorescence of marine organisms (mainly algae and coral adherents) at multiple wavelengths (four different wavelengths). This device was also developed to be mounted on a small ROV to enable fluorescence mapping of marine organisms over a wide area. Furthermore, an image processing method was investigated for the fluorescence images obtained by these developed devices.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で開発した多波長励起式蛍光撮影装置は、海洋生物が発する蛍光を画像としてとらえることで、生物マッピング撮影技術の基盤を構築した。さらに、小型ROVに本装置を搭載することで、これまで人が潜水調査で観察するには難しい水深50m以深の海域（Methophotic Zone）における生物観察とマッピングを可能にしたことは、学術的な意義が大きい。また、本装置は多少の改良が必要だが、研究協力者O.R.E（代表：鈴木貞男氏）を通じて製品化の可能性を見出した。本装置が比較的簡便・安価に製品化されれば、海洋生物観察とマッピング（環境計測）の有効なツールとなり、社会的意義がある。
