territorial sea
coastal waters that are part of a nation-state's sovereign territory
AI overview
A territorial sea is the area of ocean water that extends from a country's coastline and legally belongs to that nation, just like its land does. It matters because it gives countries control over the resources, shipping, and activities in these waters near their shores.

Maritime zones under international law
Territorial waters are informally an area of water where a sovereign state has jurisdiction, including internal waters, the territorial sea, the contiguous zone, the exclusive economic zone, and potentially the extended continental shelf (these components are sometimes collectively called the maritime zones). In a narrower sense, the term is often used as a synonym for the territorial sea.
