🎙️ Episode DescriptionIn this episode, we explore the often-overlooked dimension of cultural heritage in deep-sea mining. Matthew joins Oliver Gunasekara to examine how tangible and intangible cultural heritage intersect with seabed development. From shipwrecks and paleontological remains to Indigenous cosmologies and ancestral ties to the ocean, the conversation highlights regulatory frameworks, challenges in stakeholder engagement, and opportunities for responsible stewardship. The discussion underscores that the deep ocean archive of exploration, conflict, migration, belief, and memory requires thoughtful navigation.👤 GuestMatthew Piscitelli – Project Manager & Marketing Manager at SEARCH, a U.S.-based cultural resource management firm specializing in heritage compliance and underwater archaeology.🎧 HostOliver Gunasekara – CEO & Co-Founder of Impossible Metals⏱️ Episode Timeline* Introduction and overview of cultural heritage in deep-sea mining (00:00:00–00:01:23)* Why cultural heritage is increasingly urgent in seabed development (00:01:23–00:03:06)* Defining tangible vs. intangible cultural heritage (00:03:15–00:05:31)* Examples of tangible heritage: shipwrecks, fossils, naval wreck protections (00:05:51–00:07:27)* Shipwreck distribution data and exposure to deep-sea mining zones (00:07:42–00:10:10)* Intangible heritage: Indigenous cosmologies, seascapes, and ancestral connections (00:10:20–00:12:18)* Regulatory frameworks: UNCLOS, ISA, U.S. law, and cultural heritage provisions (00:12:52–00:15:05)* Lessons from offshore wind and terrestrial industries on compliance and engagement (00:15:52–00:18:00)* Best practices: baseline assessments, predictive modeling, and transparent communication (00:18:37–00:20:27)* Stakeholder engagement challenges: geography, consultation timelines, and global commons debates (00:26:51–00:30:03; 00:37:29–00:39:33)* Q&A highlights: AI and machine learning for archaeological detection (00:23:51–00:26:38); evaluating cultural harm and Indigenous consultation (00:30:11–00:44:10); technology claims and environmental verification (00:54:18–00:57:37)🔑 Key Takeaways* The deep ocean contains shipwrecks, paleontological remains, and places that hold cultural and spiritual meaning for many communities. It is described as an archive of exploration, conflict, migration, belief, and memory.* Cultural heritage has two dimensions. Tangible heritage includes physical artifacts, while intangible heritage encompasses beliefs, practices, and identity.* Shipwreck exposure to deep-sea mining appears limited but uncertain. Only a small percentage of known wrecks lie in potential mining depths, though data gaps remain.* Regulatory frameworks are evolving. International and national regimes address tangible heritage more clearly than intangible cultural connections.* Indigenous perspectives are central. Many Pacific and diaspora communities view the ocean as ancestral space, not empty territory.* Stakeholder engagement is complex. Geographic distance, global commons debates, and regulatory authority shape who participates in decision-making.* Baseline cultural assessments reduce operational and reputational risk. Early surveys and predictive modeling help avoid unintended impacts.* Transparency builds trust. Clear communication, science outreach, and accessible storytelling improve public understanding.* Capacity building matters. Supporting communities with resources and training strengthens meaningful participation.* Responsible access requires cultural awareness. Development and heritage stewardship are not mutually exclusive—but require deliberate integration.🔗 Links & Resources Mentioned* Impossible Metals* International Seabed Authority* National Oceanic and Atmospheric Administration* Bureau of Ocean Energy Management This is a public episode.
