飞机活动正在阿拉斯加北极地区扩大，可能会改变社会生态系统。北极社区报告说，飞机干扰野生动物，对收获做法和经验产生负面影响。有限的数据限制了对飞机在传统收获区活动程度的了解。我们的目标是使用声景监测方法来记录努伊克苏特农村生计社区周围的飞机飞越，以告知影响缓解过程。这项研究提供了第一个定量估计的飞机活动在农村北极阿拉斯加。我们在2016年夏天沿着用于收获驯鹿（Rangifer tarandus）的旅行走廊部署了20个声学监测系统。录音捕捉7465飞机事件在驯鹿收获季节的高峰期。在人类发展区附近，飞机活动达到平均每天12次，比未开发地区多约6倍。飞机噪音随着人类发展的距离而逐渐减少。鉴于自给收割者报告说，飞机惊吓驯鹿，宁愿避免飞机本身，这一结果意味着他们将需要旅行更远的成功收获，招致更高的燃料，设备和努力的成本。这样的成本对于许多收割机来说可能是令人望而却步的。我们的研究表明，声学数据可以帮助了解人与人之间的相互作用如何影响北极的社会生态动态。
Aircraft activity is expanding across Arctic Alaska, potentially changing social-ecological systems. Arctic communities report that aircraft disturb wildlife and negatively influence harvest practices and experiences. Limited data have restricted knowledge about the extent of aircraft activity over traditional harvest areas. Our objective was to use soundscape monitoring methods to document aircraft overflights around the rural subsistence-based community of Nuiqsut to inform impact mitigation processes. This study provides the first quantitative estimates of aircraft activity in rural Arctic Alaska. We deployed 20 acoustic monitoring systems in summer 2016 along travel corridors used to harvest caribou (Rangifer tarandus). Sound recordings captured 7465 aircraft events during peak caribou harvest season. Aircraft activity reached a median of 12 overflights per day near human development, approximately six times greater than undeveloped areas. Aircraft noise decreased incrementally with distance from human development. Given that subsistence harvesters report that aircraft startle caribou and prefer to avoid aircraft themselves, this result implies that they will need to travel farther for a successful harvest, incurring higher costs of fuel, equipment, and effort. Such costs could be prohibitive for many harvesters. Our research demonstrates that acoustic data can aid in understanding how human-to-human interactions impact social-ecological dynamics in the Arctic.
