The above-mentioned research shows how the scientific community is achieving sustainable development goals through different projects and networks under the framework of the Ocean Decade. These projects address not only ecosystem conservation and management, but also the integration of cultural heritage, ecosystem modeling challenges, and the integration of science and policy. Together, these efforts move us toward a cleaner, healthier and more resilient ocean. 4.2 Case study: Technological innovation promotes ocean healthy restoration Under the framework of the United Nations Decade of Ocean Science, projects and practices around the world demonstrate the important role of scientific research and technological innovation in promoting the recovery and sustainable development of ocean health. These cases not only highlight innovative approaches to solving ocean problems, but also emphasize the need for international cooperation. Below are two specific cases that illustrate in detail how these efforts are implemented in practice. GOOS is a classic example of how international cooperation and technological innovation can be used to monitor ocean health and respond to global change. The system provides real-time ocean data to scientists, policymakers and the public by integrating ocean observation resources from around the world, including satellite remote sensing, buoys, ships and seafloor observation stations. The deep sea plays a key role in climate regulation, biodiversity storage and the provision of energy, mineral and biological resources. Long-term deep-ocean exploration and observation led to the initial conception of the Deep-Ocean Observing Strategy (DOOS), which aims to integrate deep-ocean observation activities on a global scale (Figure 3). Emerging technologies relevant to deep-sea sustainability and the blue economy include novel genomics methods, imaging technologies and ultra-deep hydrographic measurements. Progress can be facilitated through open science and discoverable, accessible, interoperable, reusable (FAIR) data principles, and agreement on data standards, practices, vocabularies, and registries (Moltmann et al., 2019). Emerging observation technologies for deep-sea observation, such as remotely operated unmanned vehicles (ROVs), autonomous underwater vehicles (AUVs), and genomic analysis, have brought revolutionary progress to deep-sea research. Figure 3 Inventory of sustained deep-ocean bserving (Moltmann et al., 2019) The challenge of ocean acidification facing the U.S. West Coast shellfish industry is another striking example of how scientific research can help farmers adapt to environmental changes. In 2007, the U.S. West Coast shellfish
