The behavioural responses of migrating humpback whales to an air gun, a small clustered seismic array and a commercial array were used to develop a dose-response model, accounting for the presence of the vessel, array towpath relative to the migration and social and environmental parameters. Whale groups were more likely to show an avoidance response (increasing their distance from the source) when the received sound exposure level was over 130 dB re 1 μPa·s and they were within 4 km of the source. The 50% probability of response occurred where received levels were 150-155 dB re 1 μPa·s and they were within 2.5 km of the source. A small number of whales moving rapidly close to the source vessel did not exhibit an avoidance response at the highest received levels (160-170 dB re 1 μPa·s) meaning it was not possible to estimate the maximum response threshold.
利用迁移中的座头鲸对气枪、小型密集地震排列和商业地震排列的行为反应,开发了一个剂量反应模型,考虑到船只的存在、排列拖曳路径相对于洄游路线的位置以及社会和环境参数。当接收到的声暴露级超过 130dB re 1 μPa·s 且鲸鱼群距离震源 4 公里以内时,更有可能表现出回避反应(增加它们与源的距离)。在接收到的水平为 150-155dB re 1 μPa·s 且它们距离震源 2.5 公里以内的情况下,出现 50%反应的概率。少数快速靠近震源船只的鲸鱼在最高接收到的水平(160-170dB re 1 μPa·s)时没有表现出回避反应,这意味着无法估计最大反应阈值。
