Map describing potential MDAC coverage within pockmarks at Scanner Pockmarks SAC
A composite Habitats Directive Annex I feature extent map of Submarine structures made by leaking gases for the Scanner 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 with information extracted from previous surveys. Backscatter data and side scan sonar data was used to characterise the nature of the seafloor, in particular the presence of methane-derived authigenic carbonate (MDAC), to build a composite understanding of ÔÇ£HighÔÇØ and ÔÇ£PotentialÔÇØ Annex I feature within the site.
