Fujitsu aims to create an ocean digital twin (*2) to facilitate early verification of the efficacy of carbon neutrality and biodiversity conservation measures in the ocean. To achieve this, Fujitsu is conducting research and development of technologies for high-precision digitization of the marine environment, integrating the vast amount of data obtained from a variety of sensors mounted on underwater and aerial drones, satellites, etc, with oceanographic knowledge and AI technologies.
As part of its efforts to implement the digital twin, Fujitsu conducted a survey in the umishobu conservation area, deploying an underwater drone to capture image data. The survey confirmed that umishobu seagrass was thriving inside the conservation fence, but almost nonexistent outside the fence due to feeding damage. Moreover, it was found that vegetation other than umishobu was also growing inside the fence. The intention is to use these data as training data for AI-driven analysis to calculate the umishobu cover ratio (the ratio of plants covering the seabed), and to use this in conjunction with marine ecology to build AI models of seaweed meadows.
