An exclusive economic zone (EEZ) is a sea zone prescribed by the United Nations Convention on the Law of the Sea over which a state has special rights regarding the exploration and use of marine resources, including energy production from water and wind. It stretches from the baseline out to 200 nautical miles (nmi) from its coast. In colloquial usage, the term may include the continental shelf. The term does not include either the territorial sea or the continental shelf beyond the 200 nmi limit. The difference between the territorial sea and the exclusive economic zone is that the first confers full sovereignty over the waters, whereas the second is merely a "sovereign right" which refers to the coastal state's rights below the surface of the sea. The surface waters, as can be seen in the map, are international waters.

Within the MSP Challenge Game the EEZ indicates the Planning Region of a team. Planning outside of your team's EEZ requires the team who's border is crossed to approve the plan before implementation.

Marineregions: intersect of EEZs and IHO areas
The dataset from http://www.marineregions.org/downloads.php#iceser combines the boundaries of the world countries and the Exclusive Economic Zones of the world. It was created by combining the ESRI world country database and the EEZ V7 dataset.
2012
The layer was clipped to the extend of the North Sea, (as defined by IHO, retrieved on 2017-05-22). The geometry errors and duplicates were fixed; and the geometry was simplified to implement the layer in the MSP Challenge.
This layer is a combination of 2 sources:
Flanders Marine Institute (2012): Intersect of IHO Sea Areas and Exclusive Economic Zones.
HELCOM (2019): Exclusive Economic Zone.
Flanders Marine Institute (2012): Combination of the information on regional seas and national maritime boundaries.
HELCOM (2019): "The dataset contains the digitized Exclusive Economic Zone (EEZ) boundaries in the Baltic Sea based on the documents submitted by the Baltic Sea countries to the United Nations. These submissions, which are available online (http://www.un.org/depts/los/LEGISLATIONANDTREATIES/europe.htm), include nautical charts, maritime boundary delimitation agreements, and treaties between different countries (containing the agreed coordinates of the boundaries). In case of non-existing submission, the older EEZ version was used resulting from various HELCOM activities. The dataset has been amended with bilateral agreements, when available." Description retrieved from HELCOM's metadata page for this resource (2021-07-20)
The layer from Flanders Marine Institute (2012) was clipped to the extend of the Baltic Sea and Kattegat, (as defined by IHO, retrieved on 2017-05-22). The geometry errors and duplicates were fixed, the geometry was simplified to implement the layer in the MSP Challenge. The data was also reprojected to Lambert's Azimuthal Equal Area (EPSG:3035) projection.
The layer was updated on 2020-11-30 using the new version of the Exclusive Economic Zone of HELCOM (2019). The base layer is the one from Flanders Marine Institute (2012), the polygons were edited to match the boundaries of HELCOM (2019).
The EEZ layer in the Western Baltic Sea Edition remains consistent with that featured in the Baltic Sea edition.

In the Eastern Mediterranean Sea there are multiple National Planning Areas and disputed areas as you can see in the types below. Plans made in the disputed areas need approval from all countries in the sea basin.

Maritime Boundaries Geodatabase: Maritime Boundaries and Exclusive Economic Zones (200NM)
"Maritime Boundaries and Exclusive Economic Zones from the VLIZ Maritime Boundaries Geodatabase. Boundaries have been built using information about treaties between coastal countries. When treaties are not available, median lines have been calculated. An exclusive economic zone (EEZ) is a sea zone extending from a state's coast or baseline over which the state has special rights over the exploration and use of marine resources. Generally, a state's EEZ extends 200 nautical miles out from its coast, except where resulting points would be closer to another country. This dataset also contains delimitation of overlapping claims and joint regimes." (Retrieved from https://www.vliz.be/en/imis?dasid=6316&doiid=386 on 2023-03-39).

The dataset was clipped to the area of interest, merged boundaries belonging to the same country in different seas, removed subtractive polygons and adjusted to fit the countries' layer without overlaps or gaps.
