The third edition of the International Ocean Data Conference (IODC-3), hosted by INVEMAR in Santa Marta, Colombia, from 10-11 March 2025, gathered 400 participants worldwide—150 in-person and 250 online. Over the two days, the conference featured 40 presentations, more than 25 posters, and four topical working groups. IODC-3 brought together leading experts in marine biodiversity data, oceanography, information technology, and data science, as well as experts in ecosystem management, marine spatial planning, and even emerging topics of geodata management and marine governance in the Antarctic continent. The conference underscored the importance of strengthening data infrastructure, improving accessibility, and fostering collaboration to ensure inclusive and equitable participation in the global digital ocean ecosystem.
A key focus of IODC-3 was enhancing data interoperability and standardization to support major global frameworks, such as the United Nations Agreement on the Conservation and Sustainable Use of Marine Biodiversity Beyond National Jurisdiction (BBNJ) and the Kunming-Montreal Global Biodiversity Framework (GBF). Discussions emphasized the need for FAIR (Findable, Accessible, Interoperable, and Reusable) data principles, robust infrastructures, and harmonized methodologies to streamline data-sharing and integration efforts.
Emerging technologies, including environmental DNA (eDNA), autonomous underwater vehicles, and AI-driven interfaces, were highlighted as game-changers for marine biodiversity monitoring and conservation. These innovations facilitate cost-effective data collection, enhance biodiversity assessments, and support decision-making for marine protection. However, integrating these new data streams into existing repositories remains a challenge that requires further coordination and technical solutions.
The conference stressed the need for inclusive data collection approaches that incorporate local knowledge and regionally driven initiatives. Community-driven projects and mobile-based tools demonstrated how grassroots engagement can contribute to marine data repositories, enhancing global datasets while addressing local environmental and socioeconomic needs. Strengthening policy frameworks, improving regional monitoring, and fostering collaboration between scientific and local communities were identified as key priorities.
Capacity-building efforts remain fundamental to ensuring equitable access to ocean data. Regional collaborations, such as those within Latin America and the Caribbean, aim to enhance data-sharing and accessibility across diverse stakeholder groups. Training programs, mentorship initiatives, and the development of best practices support long-term sustainability in marine data management.
Beyond technological advancements, IODC-3 recognized the indispensable role of people in ocean data collection, curation, and application. Volunteer networks, citizen science initiatives, and workforce training are crucial in sustaining high-quality marine biodiversity information. Ensuring sustainable funding and institutional support for these efforts is essential to maintaining the long-term integrity of ocean data systems. The conference reaffirmed the urgency of building a unified and inclusive digital ocean ecosystem where scientific, cultural, historical, and local knowledge converge. Achieving this vision requires sustained efforts in data harmonization, policy alignment, and international cooperation. By strengthening these foundations, the Ocean Science community moves closer to a future where ocean knowledge is accessible, actionable, and impactful for all—a future where the Ocean Science community limitlessly shares the data we need for the Ocean we want.
