The British Geological Survey (BGS) has released a new fine-scale digital map featuring the seabed geology of offshore Anglesey. The island (in Welsh known as Ynys Môn) follows the Bristol Channel as the second in a series of new fine-scale maps that contain combined bedrock, sediment, bedrock structure and seabed geomorphology data. The maps are based on data produced by the UK Civil Hydrography Programme of the Maritime and Coastguard Agency, which includes bathymetry data, backscatter imagery, grab samples and other existing data sets such as seismic, sediment texture sheets and existing 1:250,000-scale geological maps.
