Celtic Seas Offshore habitats classified to EUNIS habitat classification. The EUNIS habitat classification is a comprehensive pan-European system to facilitate the harmonised description and collection of data across Europe through the use of criteria for habitat identification. It is hierarchical and covers all types of habitat types from natural to artificial, from terrestrial to freshwater and marine. The habitat data geographic coverage is a part of the Celtic Sea to the south of Ireland. The Celtic Seas habitats data is a collation of historical data from the 1970's, 1980's, 1990's and 2000's. The Celtic Seas offshore habitats consist of interpolated point data from the collation of historical habitat data by Aquafact Environmental Consultants as part of the Strategic Environmental Assessment of the Irish and Celtic Seas, and published in the IOSEA 4 Report. Habitat classification and extent mapping supports understanding and knowledge on the nature of the seabed. Habitat mapping translation completed by the Advanced Mapping Services data analyst within the Marine Institute (Ireland). Habitat coverage 100% for the area defined and surveyed.

Provenance information The habitat data were generated from the collation of historical habitat maps by Aquafact Environmental Consultants as part of the Strategic Environmental Assessment of the Irish and Celtic Sea and subsequently published in the IOSEA 4 Report. Hard copy versions of habitat maps were georeferenced and the habitat classes were traced and saved as polygon shapefiles using ArcMap version 10. All original classifications assigned to the habitats were translated to EUNIS using expert judgement and additional data and merged into one standardised polygon shapefile displaying EUNIS habitats in the Celtic Sea.
