The Pacific Network for Environmental Assessment (PNEA) Portal is an initiative of the Secretariat of the Pacific Regional Environment Programme (SPREP) to support government officials from Pacific Island countries and territories who work with environmental impact assessment (EIA), strategic environmental assessment (SEA) as well as Environmental and Social Safeguards (ESS).
The portal complements SPREP’s current capacity building program for EIA and SEA - including the recently launched Regional EIA Guidelines, the Coastal Tourism EIA guidelines, and SEA guidelines.

The Marshall Island Exclusive Economic Zone was measured from the low water line of the seaward side of the normal baseline (coast), the low-water line of the seaward side of the reef fringing the coast or 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 Republic of the Marshall Islands Maritime Zone Declaration Act 2016.
Nauru's Territorial Sea Baseline was defined using the 1993 topographic map produce by Survey Graphics Pty Ltd of Perth, Western Australia, under the direction of the Ministry of Island Development and Industry. The map is based on UTM Grid Zone 58, which is referred to the World Geodetic System 1972 (WGS 72). The WGS 72 coordinate system was then converted to WGS 84 using transformation parameters tabled on Nauru Maritime Boundaries Technical Report (TR 399).
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 Contiguous 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 the Contiguous zone using the World Geodetic System 1984 (WGS 84) reference datum as stipulated under the Republic of the Marshall Islands Maritime Zones Declaration Act 2016.
An exclusive economic zone extends from the baseline to a maximum of 200 nautical miles (370.4 km; 230.2 mi), thus it includes the contiguous zone.[3] A coastal nation has control of all economic resources within its exclusive economic zone, including fishing, mining, oil exploration, and any pollution of those resources.
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.
Niue's Territorial Sea Baseline was derived using the IKONOS satellite imagery taken in 2004 and Horizontal Datum used was the World Geodetic Datum 1984 (WGS 84) as stipulated under Section 12 of the Maritime Zones Act 2013.
The Maritime Zones Act 2013 states that the contiguous zone comprises those areas of the sea that are beyond and adjacent to the territorial sea, having as their outer limits a line measured seaward from the baseline, every point of which is distant 24 nautical miles from the nearest point of the baseline.
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.
Nauru Contiguous Zone was calculated from its territorial sea baseline using a special maritime boundaries delimitation software called MarZone. The Proclamation Sea Boundaries Act 1997 states the geographical coordinates are expressed using World Geodetic System 1984 (WGS84).
This dataset shows the global distribution of coral reefs in tropical and subtropical regions. It is the most comprehensive global dataset of warm-water coral reefs to date, acting as a foundation baseline map for future, more detailed, work. This dataset was compiled from a number of sources by UNEP World Conservation Monitoring Centre (UNEP-WCMC) and the WorldFish Centre, in collaboration with WRI (World Resources Institute) and TNC (The Nature Conservancy).
The USGS Earthquake Hazards Program of the U.S. Geological Survey (USGS) is part of the National Earthquake Hazards Reduction Program (NEHRP) led by the National Institute of Standards and Technology (NIST).
Dataset includes various regional-scale spatial data layers in geojson format.
This dataset is a merged layer of the 12 nautical mile zone for the Pacific region. It is the combination of the original data with SPC and data from marineregion.org.

“Territorial Sea” means the waters having as their inner limits, the baseline and as their outer
limits, a line measured seaward from that baseline, every point of which is at a distance of
twelve (12) nautical miles from the nearest point of the baseline.
The Marine Zones (Declaration) Act 2011 repeals the Marine Zones (Declaration) Act 1983. It states that the "Contiguous Zone" means waters beyond the territorial sea within a distance of twenty-four (24) nautical miles from the baselines from which the breadth of the territorial sea is measured.
