Design of Disassembly-reassembly Type USV for Coral Reef Research
AI summary Read the abstract
Researchers designed a disassembly-reassembly type unmanned surface vehicle (USV) for coral reef research, enabling physical surveys of microplastic contamination and warming impacts on coral ecosystems at depths and areas inaccessible by divers. The USV can tow sampling nets to collect microplastics and overcomes the spatial and depth limitations of conventional dive surveys.
Researchers are conducting physical surveys by diving and swimming to study the effects of microplastics and global warming on coral reefs.The area, time, and water depth that can be investigated by diving are extremely limited.In addition, to collect microplastics, it is necessary to tow the nets, but chartering a ship is expensive.Therefore, the authors are developing a system that simultaneously operates a USV and a UUV to simultaneously observe the sea surface and underwater.In this paper, we conducted a conceptual design, carried out fluid force measurements, trajectory tracking experiments, and image recognition using AI, with the aim of realizing a lightweight USV that can be divided during transportation to coral reef areas and reassembled on site for operation.

Exploring the Potential of Autonomous Underwater Vehicles for Microplastic Detection in Marine Environments: A Review
AI summary Read the abstract
This review explores how autonomous underwater vehicles equipped with sensors could detect microplastics directly in the ocean, rather than relying on labor-intensive water sampling. Current detection methods are slow and expensive, making real-time monitoring difficult. Advances in onboard sensing technology could dramatically improve our understanding of where microplastics concentrate in marine environments.
