Collaboration with Whiskey Creek Shellfish Hatchery showed that the aragonite saturation state of incoming seawater is highly correlated with larval survival (Barton et al., 2015). This work led the Pacific Coast Shellfish Growers Association (PCSGA) to begin monitoring the chemical status of shellfish hatcheries and coastal waters, establishing a collaborative monitoring network with university researchers and the U.S. Integrated Ocean Observing System in 2011 (Figure 4). Researchers use advanced monitoring technology to track changes in water quality in real time and develop mitigation strategies, such as adjusting the alkalinity of culture waters, to protect baby shellfish from acidified waters. This case not only mitigates the impact of ocean acidification on the aquaculture industry, but also provides valuable experience and technical support to other affected areas around theworld.

Inset of Willapa Bay; TK: Tokeland; BC: Bay Center (Ekone Oyster Co.); NC: Nahcotta (Jolly Roger Oyster Co.) Through these cases, we see the practical application and huge potential of scientific research and technological innovation in solving marine environmental problems. The establishment and development of the global ocean observing system has improved our understanding of ocean changes and enabled us to more effectively monitor and respond to the challenges posed by global changes. At the same time, research on specific issues (such as the impact of ocean acidification on shellfish farming) demonstrates how scientific research can be directly applied to solve practical problems, helping related industries adapt to environmental changes and ensure sustainable development. These efforts not only provide effective tools for protecting marine ecosystems, but also lay a solid foundation for achieving the goal of sustainable ocean utilization. Driven by the United Nations Decade of Ocean Science , we look forward to the successful implementation of more such projects and practices in the future to jointly promote the restoration and development of global ocean health. 5 Conclusion and Future Prospects With the implementation of the United Nations Decade of Ocean Science plan, global attention and response measures to the decline of ocean health have reached unprecedented heights.
