These national waters are subject to the territorial sovereignty of coastal nations, with certain navigational rights reserved to the international community. The second part includes contiguous zones, waters of the exclusive economic zone, and the high seas. These are international waters in which all nations enjoy the high seas freedoms of navigation and overflight. International waters are discussed further in paragraph 1.5. 1.4.1 Internal Waters.
Internal waters are landward of the baseline from which the territorial sea is measured.
Lakes, rivers, some bays, harbors, some canals, and lagoons are examples of internal waters. From the standpoint of international law, internal waters have the same legal character as the land itself. Where the establishment of a straight baseline has the effect of enclosing as internal waters areas which had previously not been considered as such, a right of innocent passage exists in those waters. 1.4.2 Territorial Seas. The territorial sea is a belt of ocean which is measured seaward from the baseline of the coastal nation and subject to its sovereignty.
