>> More Information
Even seemingly strong sections of coastline, such as these cliffs on the Dingle Peninsula, are prone to erosion.
Coastline
The coastline of Ireland is a complex environment where land meets sea. Its shape changes over time, influenced by currents, weather, erosion, and human impacts to name a few.
Sea dunes located 20 nautical miles off the south coast of Co. Wexford are one example of seabed features.
Bathymetry of Irish Waters: GEBCO Contours
The bathymetry around Ireland is diverse, with smooth, shallow sea floor close to the coast, and steep slopes of the continental margin further to the south and west.
Among details displayed in the OSI / OSNI 1:50,000 Webmap Series are names of channels, such as Bull's Mouth in Blacksod Bay, Co. Mayo.
Ordnance Survey Basemaps
Ordnance Survey of Ireland and Northern Ireland provide base information such as towns, roads, counties and rivers for the Republic and Northern Ireland. In MIDA, the 1:450,000 scale basemap changes to the more detailed 1:50,000 scale basemap as you zoom in to coastal areas.
