CEND 19x/12: Offshore seabed survey of Braemar Pockmarks SCI and Scanner Pockmark SCI 2017

Abstract

The report describes the presence, location and extent of the pockmark features, along with detail relating to the presence and location of any associated seafloor carbonate structures where they are observed to occur.

Summary

This report presents the findings from the analyses of the data gathered during the seabed survey of the Braemar Pockmarks and Scanner Pockmark Sites of Community Importance (SCI), as defined in the European Commission Habitats Directive 92/43/EEC. The pockmark features present within both of the SCIs are a series of crater-like depressions on the seafloor, and can include the Directive’s Annex I habitat ‘Submarine structures made by leaking gases’. These structures consist of large blocks, pavements, slabs and smaller fragments of carbonate rock, including methane-derived authigenic carbonate (MDAC).
