Description

The law of the sea is codified in the United Nations Convention on the Law of the Sea (LOSC), being the “constitution” of the oceans. We examine the legal regimes regulating the use of the internal waters, ports, archipelagic waters, the territorial sea, the contiguous zone, the exclusive economic zone (EEZ), the continental shelf, the area, and the high seas. We see how States establish their maritime boundaries, and how overlapping boundaries are delimited between adjacent States. We examine the legal definition of islands, rocks, low-tide elevations, installations, ships, vessels, artificial islands, as well as harbor works. We turn our attention to the environmental protection of marine areas both within and beyond any State’s national jurisdiction. The regulation of the search and rescue of migrants at sea is also included. And we pay attention to piracy and other security issues. Finally, we discuss the rules and procedures for the peaceful resolution of international ocean disputes.
