Description

According to Wikipedia, the term territorial waters is sometimes used informally to refer to any area of water over which a state has jurisdiction. In a narrower sense, the term is used as a synonym for the territorial sea and that is the definition used in the MSP Challenge.

Territorial sea, as defined by the 1982 United Nations Convention on the Law of the Sea,[2] are the coastal waters extending at most 12 nautical miles (22 km; 14 mi) from the baseline (usually the mean low-water mark) of a coastal state. The territorial sea is regarded as the sovereign territory of the state, although foreign ships (military and civilian) are allowed innocent passage through it, or transit passage for straits; this sovereignty also extends to the airspace over and seabed below. Adjustment of these boundaries is called, in international law, maritime delimitation.

MSP Challenge

Within the MSP Challenge Game the territorial waters do not have a special role and are not editable.

Back to Governance.

In this tab you can see the information that applies concretely to the North Sea edition of the MSP Challenge.

Data Source

Flanders Marine Institute (2016). Maritime Boundaries Geodatabase: Territorial Seas (12NM), version 1. Available online at https://www.marineregions.org/. https://doi.org/10.14284/243

Original Title

Territorial Seas (12NM)

Description

"Territorial Seas from the VLIZ Maritime Boundaries Geodatabase. Territorial seas are a belt of coastal waters extending at most 12 nautical miles (22.2 km; 13.8 mi) from the baseline (usually the mean low-water mark) of a coastal state." Retrieved from marine regions on 2021-07-06.

Creation Date

Methodology

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. The data layer was also reprojected to Lambert's Azimuthal Equal Area (EPSG:3035) projection.

Sand Extraction Edition

For the Sand Extraction Edition of the MSP Challenge, the territorial water line was updated, with a more recent data layer from Rijkswaterstaat called: "nautische_12mijl" accessed in 02/2025.

In this tab you can see the information that applies concretely to the Baltic Sea edition of the MSP Challenge.

Data Source

This layer is a combination of 2 sources:

Flanders Marine Institute (2016). Maritime Boundaries Geodatabase: Territorial Seas (12NM), version 1. Available online at https://www.marineregions.org/. https://doi.org/10.14284/243 HELCOM (2019)

Original Title

Flanders Marine Institute (2016): Territorial Seas (12NM)

HELCOM (2019): Territorial waters

Description

Territorial seas are a belt of coastal waters extending at most 12 nautical miles (22.2 km; 13.8 mi) from the baseline (usually the mean low-water mark) of a coastal state." Retrieved from marine regions on 2021-07-06.

HELCOM (2019): "Borders of territorial waters (12 nautical miles from baseline) in the Baltic Sea. It is based on a dataset by the European Environment Agency (https://www.eea.europa.eu/data-and-maps/data/maritime-boundaries). The Russian borders and some small segments are based in OpenStreetMap. See the attribute table for details. The Swedish territorial waters file was edited in November 2019. The source was the Swedish Maritime Administration (https://www.sjofartsverket.se/sv/Maritima-Tjanster/Havsgranser/)". Retrieved from HELCOM on 2021-07-06.

Creation Date

Flanders Marine Institute (2016): 2016-10-21 HELCOM (2019): 2017-01-01

Methodology

The layer from Flanders Marine Institute (2016) was clipped to the extend of the Baltic Sea and Kattegat, (as defined by IHO, retrieved on 2017-05-22). Geometry errors and duplicates were fixed, and the geometry was simplified to implement the layer in the MSP Challenge. The data layer was also reprojected to Lambert's Azimuthal Equal Area (EPSG:3035) projection.

The layer was updated later on 2020-11-30 using the new version of HELCOM from November 2019.

Western Baltic Sea

The Territorial Waters layer in the Western Baltic Sea Edition remains consistent with that featured in the Baltic Sea edition.

Not Applicable.

There are no territorial waters defined in the Clyde Marine Region.

In this tab you can see the information that applies concretely to the Adriatic Sea edition of the MSP Challenge.
