The network includes a system of national marine sanctuaries and marine national monuments. Few places on the planet can compete with the diversity of the National Marine Sanctuary System, which protects America's most iconic undersea natural and cultural resources. The system works with diverse partners and stakeholders to promote responsible, sustainable ocean uses that ensure the health of our most valued ocean and Great Lake places. By investing in innovative solutions, we strengthen these iconic places to address 21st-century challenges while supporting America's commerce and tourism. These unique locations inspire people to visit, value, and steward our nation's iconic ocean and Great Lakes places. The legal boundaries of the national marine sanctuaries are defined within the Code of Federal Regulations, at 15 C.F.R. Part 922 and the subparts therein. The GIS compatible digital boundary files for each national marine sanctuary are representations of those legal boundaries and are based on the best available data. These files are provided to promote an understanding of the boundaries, locations, and extents for each national marine sanctuary. They are based on the legal definition of each sanctuary as defined in the Code of Federal Regulations, at 15C.F.R. Part 922 and the subparts therein as stressed previously. These digital files are not intended and should not be relied upon for use in navigation or for legal purposes. For legal questions relating to the digital boundary files, please contact NOAA’s Office of National Marine Sanctuaries at the information provided in this metadata record. onGoing GIS Coordinator (301) 713-3125 (301) 713-0404 1305 East-West Highway, 11th Floor Silver Spring MD 20910 sanctuaries@noaa.gov pointOfContact GIS Coordinator (301) 713-3125 (301) 713-0404 1305 East-West Highway, 11th Floor Silver Spring MD 20910 sanctuaries@noaa.gov custodian daily https://americansamoa.noaa.gov/media/img/as_full-400.jpg Locator map depicting the location of NMS of American Samoa jpg American Samoa Marine NMS National Marine Sanctuary South Pacific place Sanctuary CFR Code of Federal Regulation MPA NMS National Marine Sanctuary ONMS marine protected area theme DOC/NOAA/NOS/NMS > National Marine Sanctuaries, National Ocean Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2026.

The digital boundaries were created with the most recent and accurate geospatial information available at the time of publication, but their overall extent, area, and/or proportions may change due to natural land changes along shorelines, as well as sanctuary boundary site modifications and expansions, as well as updated source data that is the basis of the boundary.

The values recorded for each attribute were quality assured and believed to be accurate. Completeness Report Where possible, the entire boundary for the sanctuary is represented by this digital file. Conceptual Consistency The data were topologically cleaned. The geographic boundary coordinates listed within the United States Code of Federal Regulations (CFR) were converted to decimal degrees and a text file was created. A point coverage was then generated using ArcInfo GIS. The coverage was projected into the Geographic Coordinate System and overlaid on large scale nautical charts and analyzed with additional data such as adjacent sanctuaries and shorelines. Specific attention was given to analysis of inconsistencies between textual descriptions and listed coordinates. The polyline files were created using a combination of the coordinate list from the CFR and applicable shoreline vector files. For point files, two methods were used. If the sanctuary had a shoreline component, a polyline to point script was used to create a point for each vertice. If a shoreline component was not present, then the original coordinates from the CFR were used to create a point shapefile. Polygon files were created by converting polylines to polygons.
