The Maritime Zones Act 2013 states that the baseline of the territorial sea of Niue is measured from the low-water mark along the coast of Niue, or where there is a coral reef along any part of the coast of Niue, the low-water mark along the outer edge of the coral reef.
The territorial sea comprises those areas of the sea having, as their inner limits, the baseline and, as their outer limits, a line measured seaward from that baseline, every point of which is distant 12 nautical miles from the nearest point of the baseline.
The Marshall Islands Territorial Sea Zone was measured from the low water line of the seaward side of the normal baseline (coast), low-water line of the seaward side of the reef fringing the coast and bounding any lagoon waters adjacent to any part of that coast. MarZone delimitation software was used to generate territorial sea limit using the World Geodetic System 1984 (WGS 84) reference datum as stipulated under the Tuvalu Maritime Zones Act 2012.
The Nauru Territorial Sea Zone was measured from the low water line of the seaward side of the normal baseline (coast) or the low-water line of the seaward side of the reef fringing the coast. MarZone delimitation software was used to generate territorial sea limit using the World Geodetic System 1984 (WGS 84) reference datum as stipulated under the Nauru Sea Boundaries Act 1997.

(a) having as their inner limits the breadth of the territorial baselines and is measured from the low-water mark along the coast of the Cook Islands or where there is coral reef along any part of the coast of the Cook Islands, the low-water mark along the outer edge of the coral reef.
The Code of the Federated States of Micronesia (FSM) was amended to include the Exclusive Economic Zone (EEZ), to increase the size of its Territorial Sea and to be inclusive of the current political status of FSM and other purpose as it deem fit (16 December 1988)
