Underwater Cultural Heritage and International Law

Recent developments in deep-sea technology, that make possible the recovery of materials from virtually the entire ocean floor, mean that marine treasure hunting has become a matter of major international interest. Sarah Dromgoole provides a clear and well-informed account of the complex and controversial international legal framework governing this issue.

The UNESCO Convention on the Protection of the Underwater Cultural Heritage 2001, which entered into force internationally in 2009, is designed to deal with threats to underwater cultural heritage arising as a result of advances in deep-water technology. However, the relationship between this new treaty and the UN Convention on the Law of the Sea is deeply controversial. This study of the international legal framework regulating human interference with underwater cultural heritage explores the development and present status of the framework and gives some consideration to how it may evolve in the future. The central themes are the issues that provided the UNESCO negotiators with their greatest challenges: the question of ownership rights in sunken vessels and cargoes; sovereign immunity and sunken warships; the application of salvage law; the ethics of commercial exploitation; and, most crucially, the question of jurisdictional competence to regulate activities beyond territorial sea limits.
