dc.descriptionThis summary for policy makers report examines the status and trends of the global open ocean under the United Nations Environment Programme Transboundary Waters Assessment Programme. It synthesises indicators, expert assessments and projections across governance, climate change, ecosystems, fisheries and pollution, using observational data and modelling. Findings show warming, acidification, deoxygenation, declining fish productivity and rising sea level risks, alongside fragmented governance and monitoring gaps across transboundary ocean systems globally.en

Assessment Approach Transboundary Waters Assessment Programme (TWAP) Indicators, indices, and monitoring framework 3. Narrative of Selected Results 3.1 Climate and Physical Ocean Changes A changing open ocean climate Projected climate change scenarios (RCP pathways) Ocean warming Ocean oxygen decline (deoxygenation) Ocean acidification Sea level rise 3.2 Human Impacts on the Open Ocean Growth of fisheries exploitation Inequities in tuna fisheries and high seas catch Pollution pressures on ecosystems (plastics, nutrients, contaminants) 3.3 Ecosystem and Biodiversity Impacts Cumulative human impact across ocean regions Coral reef vulnerability under climate and local stressors Habitat compression (e.g., pteropods and polar ecosystems) Decline in fish catch potential under climate change 3.4 Integrated Risk and Impact Assessment Sea level rise risk to coastal communities Exposure, hazard, and vulnerability framework 4. Governance of the Open Ocean Governance risk framework (hazard–exposure–vulnerability) Need for global-scale governance solutions Role of national vs transboundary governance 5. Governance Architecture and Gaps Fragmentation of global ocean governance Coverage gaps in Areas Beyond National Jurisdiction (ABNJ) Existing agreements and institutional complexity Regional and global integration challenges 6. Monitoring and Knowledge Gaps Under-observation of the open ocean Data limitations and monitoring needs Role of global observing systems (e.g., GOOS) 7. Online Resources and Further Information 8.
