Scanner Annex I Associated pockmark features

This dataset contains the findings from the analyses of data gathered during a seabed survey of Scanner Pockmark SCI. The pockmark and unit pockmark features present are a series of crater-like depressions on the seafloor. These structures consist of large blocks, pavements, slabs and smaller fragments of carbonate rock, including methane-derived authigenic carbonate (MDAC). The features are classified as the Directives Annex I habitat Submarine structures made by leaking gases even in the absence of MDAC as the qualifying feature has been recorded in the past, and the presence of leaking gases is inferred from high reflectance backscatter data.
