(Version 4.0, 7/26/2013) Maritime limits for the United States are measured from the U.S. baseline, which is recognized as the low-water line along the coast as marked on the official U.S. nautical charts in accordance with the articles of the Law of the Sea. The baseline and related maritime limits are reviewed and approved by the interagency U.S. Baseline Committee. The primary purpose of this dataset is to update the official depiction of these maritime limits and boundaries on NOAA's nautical charts. The Office of Coast Survey depicts on its nautical charts the territorial sea (12 nautical miles), contiguous zone (24nm), and exclusive economic zone (200nm, plus maritime boundaries with adjacent/opposite countries). U.S. maritime limits are ambulatory and are subject to revision based on accretion or erosion of the charted low water line.

NOAA is responsible for depicting on its nautical charts the limits of the 12 nautical mile Territorial Sea, 24 nautical mile Contiguous Zone, and 200 nautical mile Exclusive Economic Zone (EEZ). The outer limit of each of these zones is measured from the U.S. normal baseline, which coincides with the low water line depicted on NOAA charts and includes closing lines across the entrances of legal bays and rivers, consistent with international law. The U.S. baseline and associated maritime limits are reviewed and approved through the interagency U.S. Baseline Committee, which is chaired by the U.S. Department of State. The Committee serves the function of gaining interagency consensus on the proper location of the baseline using the provisions of the 1958 Convention on the Territorial Sea and the Contiguous Zone, to ensure that the seaward extent of U.S. maritime zones do not exceed the breadth that is permitted by international law. In 2002 and in response to mounting requests for digital maritime zones, NOAA launched a project to re-evaluate the U.S. baseline in partnership with other federal agencies via the U.S. Baseline Committee. The focus of the baseline evaluation was NOAA's largest scale, most recent edition nautical charts as well as supplemental source materials for verification of certain charted features. This dataset is a result of the 2002-present initiative and reflects a multi-year iterative project whereby the baseline and associated maritime limits were re-evaluated on a state or regional basis. In addition to the U.S. maritime limits, the U.S. maritime boundaries with opposite or adjacent countries as well as the US/Canada International Boundary (on land and through the Great Lakes) are also included in this dataset.

An exclusive economic zone (EEZ) is a sea zone prescribed by the United Nations Convention on the Law of the Sea over which a sovereign state has special rights over the exploration and use of marine resources, including energy production from water and wind. This maritime boundary is designed to be used with other marine boundaries in order to help determine areas of trade, commerce and transportation. The 200 NM zone is measured, country-by-country, from another maritime boundary, the baseline (usually but not in all cases the mean low-water mark, used is not the same thing as the coast line. For each country, obtain the official list of the baseline points from the United Nations under Maritime Space.The exclusive economic zone stretches much further into sea than the territorial waters, which end at 12 NM (22 km) from the coastal baseline (if following the rules set out in the UN Convention on the Law of the Sea). Thus, the EEZ includes the contiguous zone. States also have rights to the seabed of what is called the continental shelf up to 350 NM (648 km) from the coastal baseline, beyond the EEZ, but such areas are not part of their EEZ. The legal definition of the continental shelf does not directly correspond to the geological meaning of the term, as it also includes the continental rise and slope, and the entire seabed within the EEZ. The chart below diagrams the overlapping jurisdictions which are part of the EEZ. When the (EEZ) boundary is between countries which are separated by less than 200NM is settled by international tribunals at any arbitrary line. Many countries are still in the process of extending their EEZs beyond 200NM using criteria defined in the United Nations Convention on the Law of the Sea.

This edition has been superseded by the Australia's Maritime Zones Edition 4 map published in October 2013. Geocat 69822. It no longer correctly reflects Australia's maritime zones and is kept for historical record only.

This map has been derived from Geoscience Australia's Australian Maritime Boundaries (AMB) version 2.0 data which is a digital representation of Australia's territorial sea baseline and the maritime limits and boundaries as established under the Sea and Submerged Lands Act 1973.

The map describes the different maritime zones, explains how Australia defines and updates its maritime boundaries, and lists the different maritime boundary arrangements with Indonesia, Papua New Guinea, Solomon Islands, France (New Calendonia and Kerguelen) and New Zealand.

The limits of the extended continental shelf beyond the exclusive economic zone, as shown on this map, are as submitted for consideration of the United Nations Commision on the Limits of the Continental Shelf (CLCS). In accordance with Australia's request the CLCS has indicated that it will not consider the extended continental shelf appurtenant to the Australian Antarctic Territory for the time being.

This map shows the extent of Australia's maritime boundaries, stretching from Heard and McDonald Islands in the west to Norfolk Island in the east, and from the Torres Strait and Arafura Sea in the north to the Australian Antarctic Territory in the south.

This map can be purchased in either flat or folded format. Also available as GIS data or PDF.

This is a global dataset containing maritime boundaries derived fromt the VLIZ Maritime Boundaries Geodatabase. The concept of maritime boundaries is a relative new concept. Coastal states now want to delimit an area in the ocean where they have exclusive rights over the mineral and biological resources. The basis for the calculation of maritime boundaries is the declaration of a baseline. The conditions under which a state may establish such baseline are described in the United Nations Convention on the Law of the Sea (UNCLOS). A baseline of a country can be the low water line, a straight baseline (a line that encloses bays, estuaries, inland waters,...) or a combination of the two. The zone extending 12 Nautical Miles from the baseline is the Territorial Sea and the zone extending 24 Nautical Miles is the Contiguous Zone of a country. The legal Exclusive Economic Zone is the zone extending 200 Nautical Miles from the baseline. When the space between two countries is less than 400 Nautical Miles, the boundary should be the Median Line or should be described in a multilateral treaty. Multilateral treaties and documents describing the baselines of countries can be found on the website of the United Nations (http://www.un.org/Depts/los/LEGISLATIONANDTREATIES/regionslist.htm). Those documents were a major source for the development of the database.

An exclusive economic zone (EEZ) is a sea zone prescribed by the United Nations Convention on the Law of the Sea over which a sovereign state has special rights over the exploration and use of marine resources, including energy production from water and wind. The 200 NM zone is measured, country-by-country, from another maritime boundary, the baseline (usually but not in all cases the mean low-water mark, used is not the same thing as the coast line. For each country, the official list of the baseline points is obtained from the United Nations Law of the Sea Maritime Space (http://www.un.org/depts/los/LEGISLATIONANDTREATIES/regionslist.htm).

The data for this layer were obtained from http://www.marineregions.org/eezmethodology.php. The Preferred Citation for this data is Flanders Marine Institute (VLIZ) (2014), Maritime Boundaries Geodatabase, version 8 in conjunction with NOAA. The exclusive economic zone (EEZ) limits and boundaries were created for NOAA's purposes only to update the charted maritime limits and maritime boundaries on NOAA charts and for official depiction, please see NOAA's paper or raster nautical charts (Sourced from NOAA_Version 4.1, 9/10/2013). NOAA provides shapefiles of the Exclusive Economic Zones for different regions of the United States and its overseas territories. In a second phase the database of negotiated treaties from the United Nations Law of the Sea was consulted and imported into a GIS. The geographic coordinates from the documents were converted to decimal degrees and imported into a database. After importing them in ArcGIS, the points were connected by a line. The remaining boundaries were calculated in a GIS in accordance with the United Nations Convention on the Law of the Sea: a 200 Nautical Mile buffer was drawn from the baseline or a median line between 2 countries was calculated.

This map was created from the Australian Maritime Boundaries Information System (AMBIS). It depicts the various jurisdictional limits and zones which exist within Australia's maritime jurisdiction. as at 2002.

Part 2 of the Tuvalu Maritime Zones Act 2012 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 that baseline.

Where an archipelagic baseline is declared, the outer limits of the contiguous zone are a line measured seaward from that archipelagic baseline, every point of which is distant 24 nautical miles from the nearest point of that archipelagic baseline.

In addition, the Declaration of Contiguous Zone 2012 made under the MZA 2012 contains the geographical coordinate with reference to the World Geodetic System 1984 (WGS 84). The MZA of Tuvalu clearly illustrates in a map the contiguous zone of Tuvalu.

Marine jurisdictions define the U.S. boundaries and limits for sovereignty, exclusive rights, and control over maritime areas off its coast. These limits are measured from the U.S. baseline, defined as the low-water line along the coast and marked on NOAA's nautical charts, in accordance with the Law of the Sea. The U.S. Baseline Committee reviews and approves the baseline and related maritime limits. NOAA’s Office of Coast Survey updates these limits and boundaries on nautical charts, including the territorial sea (12 nautical miles), contiguous zone (24 nautical miles), and exclusive economic zone (200 nautical miles), along with maritime boundaries with neighboring countries. U.S. maritime limits are subject to changes due to natural processes such as accretion or erosion.State Seaward Boundary: Defined by the Submerged Lands Act of 1953, this boundary extends 3 nautical miles (nmi) from the baseline, except for Texas, the Gulf coast of Florida, and Puerto Rico, where it extends 9 nmi. This boundary marks the extent of state jurisdiction.Revenue Sharing Boundary: Established by Section 8(g) of the Outer Continental Shelf Lands Act, this boundary extends 3 nmi beyond the State Seaward Boundary. Revenues from resources such as oil and gas in this area are shared between the federal government and the coastal state.Territorial Sea: Extended to 12 nmi from the U.S. baseline by Presidential Proclamation 5928 in 1988, in accordance with the United Nations Convention on the Law of the Sea. The U.S. exercises full sovereignty over this area, including the airspace above and the subsoil below.Contiguous Zone: Extending from 12 to 24 nmi from the U.S. baseline, this zone allows the U.S. to enforce laws related to customs, fiscal matters, immigration, and sanitation to prevent violations within its territory or territorial sea, in line with international law.Exclusive Economic Zone (EEZ): Extending from 3 to 200 miles offshore (5 to 322 km), or 9 to 200 miles (14.5 to 322 km) offshore in western Florida and Texas, the EEZ grants the U.S. jurisdiction over economic activities and resource management, including the exploration, exploitation, conservation, and management of natural resources, in accordance with international law.Data and MetadataUS Marine LimitsUS Revenue SharingUS State SeawardOriginal Plate from 1985 Atlas: Political Boundaries and Maritime Zones (.pdf)This is a component of the Gulf Data Atlas (V1.0) for the Jurisdictions topic area.

PLEASE NOTE: These data have been updated. See Related Links for new data. Geoscience Australia has the primary role in the delineation of Australia's maritime boundaries. An output of this activity is the development of the Australian Maritime Boundaries (AMB) data. AMB is a GIS data product, replacing AMBIS 2001 Version 1.1, providing access to the data for Australia's Territorial Sea Baseline (TSB) and maritime zones.

AMB is a digital representation of Australia's territorial sea baseline and boundaries as established under the Seas and Submerged Lands Act 1973. The data also include a representation of the limits by which the adjacent areas of each of the States and of the Northern Territory are determined under the Petroleum (Submerged Lands) Act 1967. In the event of an inconsistency between AMB data and the baseline and limits under the legislation, the latter prevails.

The data have been published by Geoscience Australia in consultation with other relevant Commonwealth Government agencies including the Attorney-General's Department, the Department of Foreign Affairs and Trade and the Australian Hydrographic Office.

AMB data comprise the TSB and the outer limits of each zone, together with maritime boundaries determined by treaties between Australia and neighbouring countries. Base points that generate the zone boundaries are supplied in separate files and an extensive user guide provides useful background information. All data coordinates are supplied in the World Geodetic System (WGS 84) (ITRF 2000 @ 2000.0) which is effectively identical to the GDA94 datum.

Geoscience Australia is committed to the maintenance of the maritime boundaries data to ensure it reflects the changing nature of Australia's coastline and hence the various maritime zone limits. The data reflects the location of the coastline within the constraints of available source material at the time of production. Where major differences have since been discovered, these are listed in a table of notes and cautions.

AMB Data can now also be viewed on-line via AMSIS.
