Ireland's seabed is roughly ten times the size of its land area.
Why Seabed Mapping Matters
The deeper offshore waters were mapped as part of the Irish National Seabed Survey (INSS) between 1999 and 2005.
INFOMAR are mapping the inshore areas.
Phase 1 (2006 - 2016) mapped 26 priority bays.
Phase 2 (2016 - 2026) is mapping the remaining white areas.

We map the Irish seabed, mostly using sonar systems on boats.
We use other methods of surveying in shallow areas, unsafe for boats including LiDAR (plane), Satellite Imagery and drones.
