Relying on the United Nations Decade of Ocean Science for Sustainable Development's Ocean Negative Carbon Emission (ONCE) program, the Intelligent Coastal-Urban-Bay CO2 Emission Studies (iCUBES) project aims to provide global youth with opportunities to understand and explore the ocean, comprehend the complex relationship between marine ecology and climate change, and promote sustainable development through technological means, building a beautiful future where humans and nature coexist harmoniously. This project is scheduled to launch in 2025, planning to recruit no more than 35 students , with each program lasting one week. The project's content will cover academic seminars on ocean negative carbon emission technology, drone array applications, special lectures by renowned scholars, cultural exchanges, and maritime internships, aiming to foster mutual understanding and the spirit of international cooperation.
