Clean seas, healthy seas, predictable seas, attractive nautical charts 2022 Marine organisms actually photographed with a prototype The profiler equipped with a small camera developed for this project will be used in a free-fall towed system to conduct on-site observations in 11. It was conducted in Tokara Strait in November and December, and the particles in the images were automatically tracked and successfully classified into aggregates, macrophytoplankton, and zooplankton to some extent.The results were presented at an international conference.In the future, we will improve the accuracy of the classification technique using a camera with even higher resolution.?Duran Gomez, GS, T.

It is predicted that the marine environment of the Kuroshio Current, which flows along the southern coast, will change significantly.The Kuroshio Current carries nutrients to downstream areas in the subsurface layer.The low-order production process of the plankton community, which is supported by this nutrient supply, is particularly important for the sustainable use of marine resources in Japan. The monitoring technology has not been developed, which is an urgent issue.Therefore, in this research, using a towed vehicle equipped with a small high-resolution camera, plankton community structure and physico-biochemical parameters are observed three-dimensionally in the ocean front area. Develop a versatile free-fall towed observation method that can generateFurthermore, we will try to apply this imaging analysis method to the identification of red tide species in fish farms.Results and Future Prospects Implementation System 2022.Acquisition of marine big data, promotion of AI analysis research (10) Development of three-dimensional mapping method for marine low-level ecosystems using free-fall towed high-resolution camera-equipped observation system (FS)
