The United Nations Convention on the Law of the Sea (UNCLOS), an international agreement that defines nations' rights and responsibilities regarding the world's oceans, establishes guidelines for businesses, the environment, and the management of marine natural resources. One important aspect of this convention is the designation of a territorial sea.
The territorial sea, according to UNCLOS, extends up to 12 nautical miles from the baseline, which is usually the mean low-water mark along the coast. Within this area, the coastal state exercises sovereignty, akin to its sovereignty on land. This includes jurisdiction over the air space above, the seabed, and the subsoil.
For clarity:
| Measurement | Miles | Nautical Miles |
|---|---|---|
| Territorial Sea Limit | - | 12 |
In summary, according to the United Nations Convention on the Law of the Sea, the correct answer is that the territorial sea of a State extends to 12 Nautical Miles.
