Buoys, lightships and Large Automatic Navigational Buoys (LANBYs) have been located in areas where water levels are too deep or lighthouses would be too expensive or impractical to construct. These floating objects are anchored to the seabed. Their distinctive shapes and colors indicate their purpose and how to navigate around them. They may have lights attached, and may have a sound making device such as a gong, bell or horn. This data has been downloaded from MIDA hosted by the CMRC in UCC.

Provenance information	Records of navigational buoys and major floating aids were extracted from tabular data provided in Excel Format. The results were saved into DBF format.The DBF table with geographic coordinates was imported into ArcMap and added as an Event theme. Rotten Island H/O and Ballagh Rocks H/O are hauling off buoys and as such their positions are not defined, therefore they are not considered in this shapefile. Event theme exported as Shapefile in Irish National Grid as well as Geographical Coordinates (WGS 84).
