Protecting Underwater Cultural Heritage in International Waters

Underwater cultural heritage (UCH) sites are unique in how their artifacts and archaeological contexts differ from terrestrial heritage sites, but UNESCO notes that UCH sites in less-actively regulated areas, like international waters, are at a high risk of having their material culture remains destroyed, pillaged, or commercially exploited, especially as technological innovations continue to increase access to the deep sea and its resources. International treaties like UNESCO's 2001 Convention on the Protection of the Underwater Cultural Heritage demonstrate efforts by the international community to protect UCH, however many maritime states including the U.S. have not signed it out of a concern that the treaty oversteps the international legal framework established by the 1982 UN Convention on the Law of the Sea (UNCLOS). In order to better understand how UCH is (or is not) protected in international waters around the world, this thesis examines the threats facing UCH in international waters as well as the contemporary legal frameworks designed to protect this cultural heritage. Several solutions aimed at addressing key threats facing UCH in international waters caused by these legal and regulatory systems and which can be taken by the U.S. and international community at large are also proposed.
