GEBCO’s gridded bathymetric data sets are global terrain models for ocean and land. The grids are available to download or access through Web Map Services.

Normally, the baseline from which the territorial sea is measured is the low-water line along the coast as marked on large-scale charts officially recognized by the coastal state. This is either the low-water mark closest to the shore, or alternatively it may be an unlimited distance from permanently exposed land, provided that some portion of elevations exposed at low tide but covered at high tide (like mud flats) is within 12 nautical miles (22 km; 14 mi) of permanently exposed land.
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 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 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.
Scientific data collected on the _Westward, Corwith Cramer_, and _Robert C. Seamans_ are invaluable products of SEA’s educational research programs. SEA supports dissemination and sharing of data with educators and researchers to benefit the broader science community and the public. We aim to encourage and ensure fair access to SEA data while also preserving the intellectual property of individual researchers and seeking opportunities for collaboration.
Portions of SEA’s digital data have been contributed to a variety of national archives for specific projects; you are welcome to freely access and utilize these resources without submitting a formal request. Proper citation is expected, see format below.
## Data Citation
Any product (e.g., thesis, capstone project, report, website, graphics, publication, presentation) by any person that includes data or samples collected onboard SEA vessels should include the following acknowledgement:
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).
With a focus on the western Pacific, this portal provides ocean data relevant to a range of sectors and applications including tourism, fishing, shipping/boating, coastal inundation, environmental management etc. Designed with a user-friendly interface, the portal entry page features the applications, thereby negating the need for users to have universal knowledge of the types of information that may be relevant to their activity. The primary purpose of the portal is both data discovery, and a means of communicating ocean information.
A recently published paper, titled “Coastal proximity of populations in 22 Pacific Island Countries and Territories” details the methodology used to undertake the analysis and presents the findings. **Purpose** * This analysis aims to estimate populations settled in coastal areas in 22 Pacific Island Countries and Territories (PICTS) using the data currently available. In addition to the coastal population estimates, the study compares the results obtained from the use of national population datasets (census) with those derived from the use of global population grids.
