Another innovative approach is the use of marine organisms as bioindicators of acidification. Studies have demonstrated that gastropod shells, for example, can effectively monitor acidification in coastal areas. The shell erosion ranking system developed for these organisms provides a cost-effective and easy-to-use method for assessing acidification, potentially involving citizen scientists in monitoring efforts (Marshall et al., 2019). 8.3 Future research needs and priorities Despite significant progress, several research gaps and priorities remain. Future research should focus on understanding the synergistic effects of multiple stressors, such as warming, deoxygenation, and acidification, on marine ecosystems. Integrating these factors into experimental designs and ecological models will provide a more comprehensive understanding of their combined impacts (Andersson et al., 2015). There is also a need for long-term monitoring programs that capture the variability in carbonate chemistry and its effects on marine life. Expanding the geographic coverage of monitoring networks, particularly in underrepresented regions, will enhance our ability to detect and respond to changes in ocean chemistry (Goldsmith et al., 2019). Advancing genomic and transcriptomic studies will shed light on the adaptive potential of marine species to acidification. Identifying genetic traits associated with resilience can inform conservation and management strategies aimed at protecting vulnerable species and ecosystems (Evans et al., 2015). Fostering interdisciplinary collaborations and engaging stakeholders, including policymakers, industry, and local communities, is essential for developing effective mitigation and adaptation strategies. Bridging the gap between science and policy will ensure that research findings translate into actionable measures to address ocean acidification (Cooley et al., 2016). 9 Concluding Remarks Ocean acidification is a critical environmental issue with profound impacts on marine ecosystems and human societies. This concluding section summarizes the key findings of recent research, emphasizes the importance of continued research and mitigation efforts, and offers recommendations for policy and practice. Recent research has significantly advanced our understanding of ocean acidification and its effects on marine life and ecosystems. Studies have shown that ocean acidification affects a wide range of marine organisms, particularly those that rely on calcium carbonate for their shells and skeletons, such as corals, mollusks, and some plankton species. These organisms experience reduced calcification rates, leading to weaker structures and increased vulnerability. Additionally, changes in ocean chemistry disrupt predator-prey relationships, reproductive success, and community dynamics, leading to shifts in species composition and ecosystem functions. Human activities are also impacted, as coastal communities and industries, particularly fisheries and aquaculture, face significant economic and social challenges due to declines in marine resources. While some species exhibit phenotypic plasticity and potential for genetic adaptation, the overall resilience of marine ecosystems to acidification remains uncertain. Effective mitigation strategies are essential to reduce CO2 emissions and manage the impacts on marine ecosystems. The importance of continued research and mitigation efforts cannot be overstated. Long-term monitoring programs are essential for capturing the variability in ocean chemistry and its ecological impacts, providing crucial data for predicting future changes and informing management strategies. Investigating the combined effects of ocean acidification, warming, deoxygenation, and other stressors will provide a more comprehensive understanding of the challenges facing marine ecosystems. Advances in genomic technologies are also vital for identifying genetic traits associated with resilience, guiding conservation efforts and helping to develop breeding programs for aquaculture species. Additionally, assessing the socioeconomic impacts of ocean acidification on coastal communities and industries will inform policy decisions and support the development of targeted adaptation measures.
