Annex I habitats that are a primary reason for selection of this site

1180 Submarine structures made by leaking gases
The Braemar pockmarks are a series of crater-like depressions on the sea floor, two of which contain the Annex I habitat Submarine structures made by leaking gases. In this location, large blocks, pavements slabs and smaller fragments of methane derived authigenic carbonate have been deposited through a process of precipitation during the oxidation of methane gas. These carbonate structures provide a habitat for marine fauna usually associated with rocky reef, and very specific chemosynthetic organisms which feed off both methane (seeping from beneath the sea floor) and its by-product, hydrogen sulphide (Judd, 2001). Larger blocks of carbonate also provide shelter for fish species such as wolf-fish and cod. Close by the two pockmarks containing blocks of carbonate, to the south west, there is another block of carbonate which is not associated with a pockmark (Hartley, 2005).
