The law of the sea is an up-to-date and comprehensive treatment of this branch of public international law. It begins by tracing the historical origins of the law of the sea and explaining its sources, notably the 1982 UN Convention on the Law of the Sea. This is followed by chapters examining the various maritime zones into which the sea is legally divided, namely internal waters, the territorial sea, archipelagic waters, the contiguous zone, the continental shelf, the exclusive economic zone, the high seas and the International Seabed Area. In each case the legal nature of the zone and its physical dimensions are analysed. Separate chapters deal with the baselines from which the breadths of most maritime zones are delineated and the law governing the delimitation of boundaries between overlapping maritime zones. Later chapters discuss how international law regulates the safety of navigation, fisheries and scientific research, and provides for protection of the marine environment from pollution and biodiversity loss. The penultimate chapter addresses the question of landlocked States and the sea. The final chapter outlines the various ways in which maritime disputes may be settled. Throughout the book detailed reference is made not only to the UN Convention on the Law of the Sea, but also to other relevant instruments, the burgeoning case law of international courts and tribunals, and the academic literature.
