Ocean acidification (OA) threatens Caribbean ecosystems and the goods and services they provide (e.g., food security, employment, shoreline protection, etc.). In 2019, a resolution passed at the Cartagena Convention Conference of the Parties that called for collaboration and action for both regional bodies of the Intergovernmental Oceanographic Commission and United Nations Environment Programme to encourage greater OA monitoring capacity and multidisciplinary, inclusive stakeholder engagement. In December 2021, an OA Caribbean Community of Practice (CoP) was established to strengthen capacity for research, monitoring, mitigation, and adaptation to OA and associated stressors in the region, including Small Island Developing States. The CoP recently distributed a needs-based assessment to analyze community needs and understand how to increase OA awareness and develop relationships with diverse stakeholders. This survey analyzes current OA activities, potential projects, key infrastructure, training needs, and interest in regional coordination. Here, we present the survey results and highlight suggested actions to build resilience and strengthen the connections between communities. OA may exacerbate the impacts of stressors that countries with waters adjacent to the Caribbean face today. This CoP aims to coordinate efforts and increase capacity to monitor and mitigate OA through in-person workshops, standardization of monitoring efforts, and communication training for science and policy while advancing diversity, inclusion, and accessibility in the region.
