Arctic marine mammals are living in a rapidly changing environment. However, the impacts of increasing human activity on northern whale species and populations is poorly understood.

具体来说,人为噪音源的原始条件的丧失,预计将导致不同程度的影响,从声音掩蔽和行为干扰到极端的听力损失和死亡。此外,加拿大北极地区越来越多的船只交通造成的严重伤害或死亡的风险,对鲸鱼物种来说是越来越令人担忧。我们正在寻求采用一种多方面的研究方法,利用实验控制研究来量化船舶噪声和声纳暴露对北极鲸鱼的声学影响,并评估船舶撞击风险。

结合空中行为观察(无人机)和水下生物探测技术(长期和粗放的卫星遥测标签,带有记录水平和垂直平面上的二维运动的时间深度记录器和记录三维潜水行为和接收声音的短期高分辨率生物探测仪)、猎物场测绘(海洋学采样)和船只位置和噪音数据(AIS),我们将确定1)人为噪声对北极鲸的行为和发声(呼叫和回声定位率)的影响;2)潜水行为对船只撞击风险的影响;3)我们可以减轻影响以减少干扰、伤害和死亡的风险。

我们的研究成果将直接支持国防部关于在北极地区使用声纳的风险缓解行动,并将有助于加拿大渔业和海洋部对海洋航运和环境对北极鲸鱼影响的适应性反应。我们的项目将通过评估海洋航运和渔业活动对北极鲸鱼的累积影响,建立更强大的土著伙伴关系,并让沿海社区参与进来。
