| Summary: | 1. Management interventions to reduce human-wildlife conflict can have unintended consequences for non-target species. Acoustic deterrent devices (ADDs) are used globally by the aquaculture sector. However, the potential for these sound emissions to impact non-target species, such as cetaceans, has not yet been quantified at population relevant spatial scales. 2. To better understand the extent of potential impacts on cetaceans, such as harbour porpoises, we used acoustic modelling to investigate levels of ADD noise throughout the west coast of Scotland and across a Special Area of Conservation (SAC) for this species. 3. Using an energy-flux acoustic propagation model and data on aquaculture sites known to be using ADDs, we predicted the spatial extent of ADD noise on the Scottish west coast from the 1st February 2017 to 31st January 2018. Noise maps were produced to determine the risk of auditory impairment for harbour porpoises under a range of scenarios which assumed single or multiple ADDs and ... : FILE: Findlay_etal_JournalAppliedEcology_NatureScot2018Data.xlsx Locations of aquaculture sites on the west coast of Scotland using Acoustic Deterrent Devices (ADDs) were obtained from information submitted to the Marine Scotland – Licensing Operations Team in fulfilment of seal shooting license applications (NatureScot, 2018), and consequently may not include all sites using ADDs in 2017. Aquaculture site names have been redacted but data includes the source locations (latitude and longitude in decimal degrees), ADD type deployed (Ace Aquatec US3, Airmar, Terecos Type DSMS-4 and OTAQ SealFence) and whether or not sites were included (Y/N) in model simulations. FILE: Findlay_etal_JournalAppliedEcology_ValidationData.xlsx The excel file contains the measured and modelled sound exposure levels (SELs; dB re 1 dB re 1 µPa2s over 1-second) for 8, 10 and 12.5 kHz 1/3 Octave Frequency Bands (TOBs) produced by a Gael Force SeaGuard ADD (https://www.gaelforcegroup.com) which was deployed at three sites on the west ... |
