Book excerpt: This is the first comprehensive study on archipelagic regimes published since the adoption of the United Nations Convention on the Law of the Sea in 1982. The book traces the historical evolution of the archipelagic concept in international law and examines the definition of archipelagos and archipelagic states. The nature, status and regime of the waters of different types of archipelagos is examined and analysed from the perspective of archipelagic states and is based on the requirement of such states for territorial integrity and self-determination. The book introduces the concept of `Ocean States' and links Ocean States with the archipelagic concept. The archipelagic concept is viewed as a practical as well as a functional basis for the determination of the territorial limits of Ocean States.
