2023-2024, NRW, Cefas, Bangor University, Welsh Acoustic Marine Mammal Survey (WAMMS), Soundtraps amd FPODs Data series https://portal.medin.org.uk/portal/start.php?tpc=015_e3e15a34-1e8e-4c4c-a621-f8ff052e3679 The Welsh Acoustic Marine Mammal Survey (WAMMS) aim was to develop an effective and robust method for measuring underwater noise and the occurrence of cetaceans (whales, dolphins and porpoises) in marine protected areas (MPAs) around the Welsh coastline. To test and demonstrate these monitoring methods, an 18-month pilot study was undertaken as part of the project in the North Anglesey Marine Special Area of Conservation (SAC). As well as illustrating how monitoring could be carried out elsewhere in Welsh marine waters, this pilot study provided baseline data on ambient noise and marine mammal detections at the site. The final field report and data analysis can be found here - https://cdn.cyfoethnaturiol.cymru/fyujoivu/wamms-final-field-report-clean-_nrw-comments-20250228-digital-copy.pdf The Phase 3 Report: Options for an all-Wales monitoring programme for underwater noise and cetaceans can be found here - https://cdn.cyfoethnaturiol.cymru/z0ephnok/wamms-phase-3-report-nrw-comments-20250320-vfinal-qcd-clean-digital-hc.pdf Three monitoring locations were selected within the North Anglesey Marine SAC: one at Holyhead deep, two off Point Lynas and one situated 1.7km off the coast and the other 5.2 km, at the boundary of the SAC.
