Site overview: The seabed in this site is 1388 km2 and was shaped by glacial and subterranean activity. It is 23km northwest from the coast of Anglesey in north Wales. The site is made up of rocky habitats and sands and gravel. Lots of smaller sea creatures such as worms live between the rocks. Methane gas leaks out of the seabed here and forms carbonate slabs.
