    "name": "Acoustic Multibeam Echosounder Survey of Turbot Bank Pembrokeshire (March 2012)",
    "description": "A multibeam echosounder survey was commissioned by former Countryside Council for Wales (CCW) in March 2012 over Turbot Bank, Pembrokeshire. This was completed by EMU Ltd at the end of March 2012 to International Hydrographic Organisation (IHO) Order 1a standards. The data have been verified by the United Kingdom Hydrographic Office (UKHO) and fully tidally corrected to chart datum. The dataset shows the dominant bedform over the bank to be large to very large dunes, with bedrock visible on the eastern edge of the study area. Further data use and analysis by CCW should help to delineate features for mapping purposes, and monitor change over time. The purpose of this data capture is to obtain bathymetry and backscatter datasets of the study area with 100% coverage.",
