1. Habituation to an acoustic harassment device (AHD) by killer whales depredating demersal longlines

   in deterring depredation we experimentally tested a high amplitude device (195 dB re 1 μPa 6.5 kHz 1 ... m from the source) from a Patagonian toothfish longliner operating off the Crozet Islands while it ... a 10- 300 m range from the vessel, as they only have access to fishing gear during hauling. We ... fled over 700 m away from the vessel when first exposed to the AHD. However, they remained within a 10 ...
