maritime border

A maritime border is the boundary dividing the territorial waters and exclusive economic zones of two or more countries in the ocean or sea. It determines where one nation's jurisdiction ends and another's begins, affecting rights over natural resources like fish and minerals. These borders are established through international agreements and treaties, respecting global laws such as the United Nations Convention on the Law of the Sea (UNCLOS). Accurate delimitation helps prevent conflicts and manages sea resources fairly among neighboring nations.
