Multibeam Surveys; St David’s Head Pembrokeshire and North West Anglesey

Welsh Government

All survey work was completed by ABPmer on behalf of Welsh Government. Two areas were chosen for the survey work off covering two broad geographical areas, St David’s Head, Pembrokeshire; and an area to the west of Anglesey. Surveys were conducted during July and August 2019. When collecting multibeam data, an appropriate overlap was maintained to ensure that 100% coverage is achieved without any data gaps or holes. Appropriate statistical analysis of cross line / main line intersections was done to assess the quality of the data.

This project has received funding through the European Maritime and Fisheries Fund, which is funded by the European Union and the Welsh Government.
