Statement

The delineation and classification of the geological substrate units were based primarily on what can be observed and interpreted from the multibeam echo-sounder (MBES) bathymetry data collected during the Civil Hydrography Programme (CHP) surveys managed by the Maritime and Coastguard Agency (MCA) and a candidate Marine Conservation Zone (MCZ) survey for the Department for Environment, Food and Rural Affairs (Defra). The two survey areas mapped were: • HI1420 – Off Skerries TSS Blk A-E 4m SB (2013) • 118503 North St Georges Channel MCZ 4m SB (2012) MBES backscatter, physical samples (e.g. grabs, cores, and boreholes) and previous geological mapping were also used to further inform the geological interpretation. The geological interpretation was undertaken in 2020-2021, by A. Finlayson, E. Phillips, R. Kendall, G. Carter and J. Everest in an ESRI ArcGIS project using the BGS SIGMA Desktop application. The geological linework was captured at a scale ranging from 1:5000 to 1:7000, to ensure smooth linework when the dataset is viewed at a scale of 1:10000. Bedrock and superficial deposits were mapped into two independent SIGMA layers and later merged to create the Seabed Substrate layer included in this dataset. Additional attribute fields were added to the layers, in particular to the geomorphology, to complement the information captured automatically by the SIGMA. The methodology used is described in more detail in the user guide for this dataset OR/22/059.
