Digital Archaeology Underwater: Ethical, Epistemic, and Climate Challenges for a Collaborative Future

This article explores the converging challenges and opportunities at the intersection of underwater cultural heritage, digital archaeology, and participatory science. In an era of accelerated climate change, data fragmentation, and rapid technological advancement, underwater archaeology is being reshaped by the rise of generative artificial intelligence (GAI), FAIR (Findable, Accessible, Interoperable, and Reusable) data governance, and the growing role of public archaeology. We argue for an ethical and epistemologically inclusive framework that recognizes the importance of co-authorship, data transparency, and multisensory narratives in interpreting submerged sites. Drawing on case studies from Latin America and Europe, this article demonstrates how socio-technical networks, collaborative models, and culturally sensitive ontologies offer a pathway toward a decolonized, accessible, and sustainable archaeology. This paper concludes with recommendations for integrated public policy and citizen-driven heritage protection, highlighting digital archaeology’s transformative potential in the Anthropocene.
