Hatton-Rockall Basin

Site overview: This site is located in the far west of Scotland’s offshore waters. Rockall Bank lies to the east, Hatton Bank to the west, and George Bligh Bank to the north. This is a really deep muddy area which is home to animals that don’t require much natural light! The site is important because it aims to protect unusual groupings of deep-sea sponges which are classed as a declining habitat. It is an unusual area as it is made up of polygonal faults which are cracks in the seafloor. They look like the cracks found on a sun scorched desert, creating a unique relief on the seabed providing a habitat for deep-sea sponges.
