Seabed
The seabed under the Celtic Sea is called the Celtic Shelf, part of the continental shelf of Europe. The northeast portion has a depth of between 90m and 100m, increasing towards Saint George's Channel. In the opposite direction, sand ridges pointing southwest have a similar height, separated by troughs approximately 50m deeper. These ridges were formed by tidal effects when the sea level was lower. South of 50° the topography is more irregular.
Oil and gas exploration in the Celtic Sea has had limited commercial success. The Kinsale Head gas field supplied much of the Republic of Ireland in the 1980s and 1990s.

And all the dry seabed unlocked,
I sent my creature scouting on the globe,
That globe itself of hair and bone....”
