    Title:
    USEEZ: Boundaries of the Exclusive Economic Zones of the United States and territories
    Abstract:
    Exclusive Economic Zone (EEZ) and Maritime Boundaries; Notice of Limits By Presidential Proclamation No. 5030 made on March 10, 1983, the United States established an exclusive economic zone, the outer limit of which is a line drawn in such a manner that each point on it is 200 nautical miles from the baseline from which the breadth of the territorial sea is measured. The U.S. EEZ is the largest in the world, containing 3.4 million square miles of ocean and 90,000 miles of coastline. The Government of the United States of America has been, is, and will be, engaged in consultations and negotiations with governments of neighboring countries concerning the delimitation of areas subject to the respective jurisdiction of the United States and of these countries. The limits of the exclusive economic zone of the United States as set forth below are intended to be without prejudice to any negotiations with these countries or to any positions which may have been or may be adopted respecting the limits of maritime jurisdiction in such areas. Further, the limits of the exclusive economic zone set forth below are without prejudice to the outer limit of the continental shelf of the United States where that shelf extends beyond 200 nautical miles from the baseline in accordance with international law.
    Supplemental_Information:
    The following is provided verbatum from the Federal Register: [Federal Register: August 23, 1995 (Volume 60, Number 163)][Notices][Page 43825-43829] From the Federal Register Online via GPO Access [wais.access.gpo.gov][DOCID:fr23au95 113]DEPARTMENT OF STATE[Public Notice 2237] Exclusive Economic Zone and Maritime Boundaries; Notice of Limits By Presidential Proclamation No. 5030 made on March 10, 1983, the United States established an exclusive economic zone, the outer limit of which is a line drawn in such a manner that each point on it is 200 nautical miles from the baseline from which the breadth of the territorial sea is measured.

Further, the limits of the exclusive economic zone set forth below are without prejudice to the outer limit of the continental shelf of the United States where that shelf extends beyond 200 nautical miles from the baseline in accordance with international law. The following notices have been published which have defined the United States maritime boundaries and fishery conservation zone established March 1, 1977: Public Notice 506, Federal Register, Vol.41, No. 214, November 4, 1976, 48619-20; Public Notice 526, Federal Register, Vol. 42, No. 44, March 7, 1977, 12937-40; Public Notice 544, Federal Register, Vol. 42, No. 92, May 12, 1977, 24134; Public Notice 4710-01, Federal Register, Vol. 43, No. 7, January 11, 1978, 1658; Public Notice 585, Federal Register, Vol. 43, No. 7, January 11, 1978,1659; Public Notice 910, Federal Register, Vol. 49, No. 155, August 9,1984, 31973. This Public Notice supersedes all limits defined in the above Public Notices. Therefore, the Department of State on behalf of the Government of the United States hereby announces the limits of the exclusive economic zone of the United States of America, within which the United States will exercise its sovereign rights and jurisdiction as permitted under international law, pending the establishment of permanent maritime boundaries by mutual agreement in those cases where a boundary is necessary and has not already been agreed. Publication of a notice on this subject which is effective immediately upon publication is necessary to effectively exercise the foreign affairs responsibility of the Department of State.

Why was the data set created?

The purpose of this data layer is to provides a general basemap showing the extent of the U.S. Exclusive Economic Zone. The EEZ consists of those areas adjoining the territorial sea of the U.S., the Commonwealth of Puerto Rico, the commonwealth of the Northern Mariana Islands, and U.S. overseas territories and pssessions. The EEZ extends up to 200 nautical miles (370 km) from the U.S. coastline. About 15 percent of this area lies on the geologic continental shelf and is shallower than 200 meters. Within its EEZ, the U.S. has sovereign rights over all living and non-living resources. Other nations may exercise freedom of vessel navigation and overflight within the U.S. EEZ (Source: Year of the Ocean Discussion Papers 1998; 2nd Ed. of Coastal and Ocean Law by Kalo et al. 1994).


How was the data set created?

  1. From what previous works were the data drawn?

    useez.e00 (source 1 of 1)

    Type_of_Source_Media: online
    Source_Contribution:
    The Arc/Info export file contains the extent of the US Exclusive Economic Zone and was downloaded from NOAA's anonymous ftp site. This complete dataset is no longer available from the NOAA website. The EEZ boundary is now available by region and is contained within zipped files. Within each zipped file, there are two sets of files-- 1) a dbase IV file containing points representing the outer boundary and 2) a shapefile representing the points as a single polyline.

  2. How were the data generated, processed, and modified?

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?

    All attributes were supplied with NOAA 'e00' dataset are Arc/Info related. There are no polygon attributes in the Exclusive Economic Zone geography.

  2. How accurate are the geographic locations?

  3. How accurate are the heights or depths?

  4. Where are the gaps in the data? What is missing?

    This is the complete, unaltered EEZ file as downloaded from the NOAA ftp site. NOAA now distributes the EEZ boundary as separate files based on geographic region.

  5. How consistent are the relationships among the observations, including topology?

    No additional checks for topological consistency were performed on the data.


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
