The ASTER Global Digital Elevation Model (GDEM) Version 3 (ASTGTM) provides a global digital elevation model (DEM) of land areas on Earth at a spatial resolution of 1 arc second (approximately 30 meter horizontal posting at the equator).
The development of the ASTER GDEM data products is a collaborative effort between National Aeronautics and Space Administration (NASA) and Japan’s Ministry of Economy, Trade, and Industry (METI). The ASTER GDEM data products are created by the Sensor Information Laboratory Corporation (SILC) in Tokyo.
Since 1972, the joint NASA/ U.S. Geological Survey Landsat series of Earth Observation satellites have continuously acquired images of the Earth’s land surface, providing uninterrupted data to help land managers and policymakers make informed decisions about natural resources and the environment.
SENTINEL-2 is a wide-swath, high-resolution, multi-spectral imaging mission, supporting Copernicus Land Monitoring studies, including the monitoring of vegetation, soil and water cover, as well as observation of inland waterways and coastal areas.
The SENTINEL-2 Multispectral Instrument (MSI) samples 13 spectral bands: four bands at 10 metres, six bands at 20 metres and three bands at 60 metres spatial resolution.
dataset with internet direct links and resources relating to the global seafloor geomorphic features that represents an important contribution towards the understanding of the distribution of blue habitats. Certain geomorphic feature are known to be good surrogates for biodiversity. For example, seamounts support a different suite of species to abyssal plains.

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.
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 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).
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:
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.
