  • A composite Habitats Directive Annex I feature extent map of Submarine structures made by leaking gases for the Braemar Pockmarks SAC was created by British Geological Survey for JNCC to provide the most up-to-date knowledge of Methane-Derived Authigenic Carbonate (MDAC) coverage within the site. Existing polygon data from the 2012 JNCC/CEFAS survey (CEND19x/12 ) was combined groundtruthing information (PB and BGS datasets), to build a composite understanding of “High” and “Potential” Annex I feature within the site.
