Reversing the Blue Decline: Strategies and Practices of the Ocean Science Decade for Global Ocean Health Recovery

As the health of the global oceans continues to decline, biodiversity is severely threatened, and human well-being is challenged. The United Nations Decade of Ocean Science for Sustainable Development (referred to as "the Ocean Decade") aims to reverse this trend through scientific research and technological innovation, providing a solid scientific foundation and practical pathways for the sustainable development of the oceans. This study focuses on the core goals and strategic priorities of the Ocean Decade, exploring in detail how scientific research and technological innovation can help understand and address the causes of ocean health decline, and how these efforts can promote the recovery and protection of marine ecosystems. By analyzing specific case studies, this research demonstrates successful projects implemented globally, such as the establishment of the Global Ocean Observing System and protection projects for key marine ecosystems, and how these projects offer viable solutions for the restoration of ocean health. This study aims to emphasize the central role of scientific research and technological innovation in addressing global ocean challenges and promoting sustainable development of the oceans. It is hoped that the discussions in this study will provide references and insights for future ocean science research and policy-making.
