This dataset consists of all identified shipwrecks and aircraft wrecks that fall within Northern Ireland's Marine Plan extent. These include wrecks which have been designated under the Protection of Wrecks Act 1973 (PWA 1973), the Protection of Military Remains Act 1986 (PMRA 1986) and the Historic Monuments and Archaeological Objects NI Order 1995 (HMAOO 1995). These designated heritage assets have been labelled accordingly. The dataset includes detailed information on each wreck; including the name of the vessel, type of vessel, accuracy of the position data, condition, date of sinking, and the UK Hydrographic Office number (if the location has been verified by UKHO). Wrecks for which there is only documentary evidence are not included; they are recorded on the Density of Documented Losses layer on the NI Marine Map Viewer and Historic Environment Map Viewer. The dataset was reviewed as part of DAERA's 2023 coastal heritage resources mapping project and all information previously compiled was updated at this time.
