Acoustic Multibeam Echosounder Survey of Turbot Bank Pembrokeshire (March 2012)
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.

Full hydrographic multibeam survey using Applanix POS MV positioning system and RESON 7125 multibeam echosounder. Vessel survey lines were run to obtain 100% seabed coverage. Dataset commissioned as a one-off and will be come part of the CCW acoustic data archive. The data have been submitted to the UK Hydrographic Office for verification, and to be made freely available to anyone who requests it as part of the UKHO multibeam bathymetry data archive centre (DAC). This dataset will also be made available by CCW under the pan-Governmental data sharing agreement for multibeam data (See DCT-11-107096).
