The effect of acoustic harassment devices on harbour porpoises (Phocoena phocoena) in the Bay of Fundy, Canada (2002, unknown): “As well, Morton and Symonds (2002) correlated a significant decrease in the occurrance of killer whales (Orcinus orca) in the same area while AHDs were active.”
Acoustic quality of critical habitats for three threatened whale populations (2014, background): “This site used to provide important feeding habitat for resident killer whales, until acoustic harassment devices (AHDs), deployed to displace seals from open-net salmon fish farms, inadvertently displaced killer whales from this part of their range (Morton & Symonds, 2002).”
A Brief Review of Known Effects of Noise on Marine Mammals (2007, background): “Other examples of apparent tolerance can be found in sperm whales with seismic surveys in Norway (Madsen, Møhl, Nielsen, & Wahlberg, 2002), blue (Balaenoptera musculus) and fin whales with LFA sonar (Croll et al., 2001) and sea lions (Zalophus californianus) to AHDs (NMFS, 1996).”
The impacts of anthropogenic ocean noise on cetaceans and implications for management (2007, background): “Killer whales stayed away for about 6 years, only returning when devices were discontinued in the area (Morton and Symonds 2002).”
Implications for marine mammals of large-scale changes in the marine acoustic environment (2008, background): “For example, Morton and Symonds (2002) surveyed killer whales in British Columbia, Canada, to evaluate avoidance of acoustic harassment devices that were placed for many years near fish farms in an attempt to keep marine mammals from depredating the fish.”
Interactions between Cetacean and Fisheries in the Southern Ocean (2006, background): “The use of acoustic deterrents, for example, may mediate the problem for orcas (Mate and Harvey 1987; Richardson et al. 1995; Jefferson and Curry 1996; Morton and Symonds 2002).”
Attraction and repulsion of mobile wild organisms to finfish and shellfish aquaculture: a review (2018, background): “…cetaceans, including porpoises and killer whales, displacing these marine mammals large distances from farms protected in this manner (Mate & Harvey 1987, Gordon & Northridge 2002, Johnston 2002, Johnston & Woodley 1998, Morton 2000, Morton & Symonds 2002, Strong et al. 1995, Taylor et al. 1995).”
Do Marine Mammals Experience Stress Related to Anthropogenic Noise (2007, unknown): “Morton & Symonds, 2002 Beluga Boat noise Masking?”
Anthropogenic sound and marine mammal health: measures of the nervous and immune systems before and after intense sound exposure (2004, background): “…à des sons (des impulsions sonores uniques sous-marines pouvant atteindre 200 kPa) produits par un canon sismique à eau et (ou) des tons purs uniques (pouvant atteindre 201 dB re µPa), qui ressemblent à des « pings » de sonar, afin de mesurer les paramètres neurologiques et immunitaires.”
Behavioral biology of marine mammal deterrents: A review and prospectus (2013, background): “Acoustic deterrent device usage remains controversial because of the risk of harming pinniped hearing and disturbing non-target wildlife (Gordon and Northridge, 2002; Morton and Symonds, 2002).”
