Exclusive Economic Zones (EEZ)

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.
