This classification was produced using approach similar to the used by BGS in creation of seabed sediments maps. The interpretation used data from surface grab samples and surface sub-samples from vibro core samples. Each sample was colour coded following detailed particle size analysis based on Folk classification. This data was incorporated within GIS and interpreted together with multibeam backscatter and shaded relief. This exercise allowed interpolation between areas where sample data was absent. Moreover, this interpretation was supported with video dive data. Thus, this study produced seabed sediment type facies interpretation for selected study areas that added more detail to the existing BGS maps. The original classes assigned to the data were translated to the EUNIS habitat classification system as part of the MESH Atlantic project.

Provenance information Acoustic classes were generated from the analysis of MBES data, collected as part of the INFOMAR national seabed mapping programme, using QTC Multiview software. Supervised classification of the acoustic classes into sediment classes was done using information from sediment grab samples and cores. The original substrate classes assigned to the data were translated to the EUNIS habitat classification system as part of the MESH Atlantic project.
