Broadscale habitat (EUNIS level 3) for South Rigg recommended Marine Conservation Zone (rMCZ)
A broadscale habitat map was produced by analysing and interpreting the acoustic and ground truth data collected at South Rigg rMCZ. Acoustic data was used to identify areas of Rock and sediment and groundtruthing data was used to divide the sediment areas into one of the four sediment classes, namely coarse sediment, sand, mud and mixed sediment. These areas were then divided into littoral and subtidal zones and different energy areas (Low, Moderate or High). These classes could then be classified using EUNIS.

Updated version of CMRS_20150216_BSH, where 'A5.1 Subtidal coarse sediment' has been reclassified as 'A5.1/ Subtidal coarse/mixed sediment', to account for the mixed sediment observed in ground truth data alongside the coarse sediment. A new habitat map for the site was produced by analysing and interpreting the available acoustic data and the ground truth data collected by the dedicated survey of the Compass Rose rMCZ, in addition to existing modelled bathymetry (Astrium, 2011). The process involves geological review and expert judgement to interpret the sediment textures present. To map substrata type across the rMCZ, we assessemed the sea bed and generated line work based on MBES, backscatter and derivatives (rugosity, slope) in conjunction with ground truth information (PSA, video and stills) in order to assign BSH classsifications. For further information, refer to the Compass Rose rMCZ Post-survey Site Report (Stewart and Green, 2015).
