The case studies in this book and the interventions from the International Seabed Authority (ISA) (see Appendix) meetings showcase the types of Ocean Heritage, natural and cultural, tangible and intangible, that may be lost if deep sea mining (DSM) goes ahead. The chapters also provide some suggestions to protect heritage in the deep sea for future generations. For example, exclusion zones, as seen with dredging regulations (Chap. 5 , this vol.). What is needed most, is surveys of the Ocean Heritage in the deep, especially in zones proposed for mining. We cannot protect heritage we do not know about. These surveys must be done to standards that archaeologists can work with, and the results should be publicly available. Underwater cultural heritage (UCH) must be included in these surveys along with natural heritage and environmental impact assessments. This is because UCH can support ecological marine biodiversity and help boost sea connectivity. Understanding UCH, including intangible UCH, is also key to respecting international commitments to human rights (including intergenerational rights, the right of public participation, the right to culture, and Indigenous peoples’ rights).
