Scanner Pockmark

Site overview: This site is approximately 185km off the north east coast of Scotland near the centre of the Witch Ground Basin, in waters of approximately 150 m depth. This area has a unique feature - blocks made by leaking gases. Anemones and squat lobsters live on these rocks. Fish (hagfish, haddock, wolf-fish and small redfish) also appear to be using the depressions in these structures for shelter.
