Limits and Boundaries - Northern Ireland Zone

This layer shows the limits of the territorial sea of the United Kingdom which are to be treated as adjacent to Northern Ireland as defined in The Adjacent Waters Boundaries (Northern Ireland) Order 2002.

This is a modified version from the UKHO Law of the Sea department data, available via https://www.gov.uk/guidance/inspire-portal-and-medin-bathymetry-data-archive-centre. The data is derived from UK 12nm limit, combined with:

• The Scottish Adjacent Waters Boundary Order 1999 (http://www.legislation.gov.uk/uksi/1999/1126/note/made)
• The Territorial Sea Act 1987 (Isle of Man) Order 1991 (http://www.legislation.gov.uk/uksi/1991/1722/schedule/made) 
• The Welsh Zone (Boundaries and Transfer of Functions) Order 2010 (http://www.legislation.gov.uk/uksi/2010/760/contents/made) .
