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.

The multibeam dataset collected was used to semi-automatically map and characterise the morphology of the pockmarks. The information extracted from the mapped pockmarks was then compared to the 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). CEND19x/12 SURVEY datasets: The survey took place between the 17th November and the 1st December 2012 on-board the CEFAS Endeavour. Data collected include: Multibeam and Sidescan sonar transect providing backscatter and bathymetry data of the area; 77 video clips and 600 stills obtained during 22 drop camera transects; 0.1 m2 grab samples were subsampled for Particle Size Analysis (PSA), the remaining material was washed over 5 mm and 1 mm sieves to retain benthic fauna. SEA2 survey Multibeam map acquired during the OSAE for the SEA2 Project in 2001 was also used to create this map. BGS DATASET: As well as the published maps [Bressay Bank, Sheet 59┬░ N-00┬░, 1:250,000 Series, Seabed Sediments (published 1987) and Quaternary Geology (published 1986); Fladen, Sheet 58┬░ N-00┬░, 1:250,000 Series, Seabed Sediments (published 1986) and Quaternary Geology (published 1988)] and the regional report (Johnson et al., 1993), the original sampling records (seabed grab, vibrocore) and geophysical data (primarily deep tow boomer, sparker and side-scan sonar) provide information on the shallow geological and seabed conditions (for Report in additional resources). These data were primarily collected in the 1970s and 1980s as part of the regional mapping programme on behalf of the Department of Energy, later Department of Trade and Industry. It has been supplemented by additional data from commercial and governmental sources. For more information see section 2 of the Report in additional resources (Gafeira and Long, 2015).
