Site overview

This site is to the west of Scotland, about 200km from the Outer Hebrides in the Rockall Trough, a deep water channel in the north-east Atlantic. The seamount is a former volcano, roughly circular in shape, and was last active 40 to 70 million years ago. The site contains a series of bedrock, stony and biogenic reefs which are home to sea cucumbers, brittlestars, cup corals and sponges.
