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.

False series At the three proposed monitoring locations, underwater noise data will be collected using the latest generation of Soundtraps (ST600HF, Ocean Instruments NZ) as well as click detector FPODs (Chelonia). Equipment will be deployed over an 18-month field season (May 2023 – November 2024) to better understand ambient noise levels and cetacean presence in the North Anglesey Marine SAC.
