Low-Tide Elevation

Offshore land features such as shoals, rocks, or reefs that are exposed at low tide but submerged at high tide are referred to as low-tide elevations.

If a low-tide elevation lies at least partially within the normal breadth of the Territorial Waters of a nation, the low-water line of that elevation may be used as a baseline for measuring the ultimate reach of the territorial sea of that nation. Those low-tide elevations lying totally outside the usual breadth of the territorial sea do not expand the reach of the territorial sea of a nation.
