Determining Marine Mammal Distribution and Ambient Noise Using Passive Acoustic Deployments in the Northern Bering Sea and Bering Strait Region, 2015-2017

In this study, we integrated and analyzed new and existing sound recordings from the northern Bering and southern Chukchi Seas to provide data on marine mammal presence and noise levels for this area. Sound recordings collected in numerous biologically important and poorly studied areas were analyzed to determine marine mammal presence through the detection of their vocalizations. These recordings, made throughout the year were collected from different acoustic monitoring projects at strategic locations, such as the Bering Strait and Anadyr Strait, west of St. Lawrence Island. The resulting data from previous deployments (spanning 5 years), as well as strategic new deployments, constituted an important baseline from which were assessed for both ambient noise (natural and anthropogenic) and biological patterns, and allowed us to anticipate future impacts associated with increasing shipping, resource extraction and climate change. Data are presented as two CSV files: NPRB1511_Deployments_metadata.csv NPRB1511_Marine_Mammal_detections_metadata.csv Result figures from study calculations are included in folders corresponding to month of data collection. This dataset was generated as part of NPRB project 1511

本研究整合并分析了北白令海与楚科奇海南部的全新及现存声学录音数据，旨在为该区域提供海洋哺乳动物分布及噪声水平相关资料。研究针对众多具有重要生态意义但研究程度较低的区域所采集的声学录音展开分析，通过检测海洋哺乳动物的发声信号以确定其存在情况。这些全年采集的录音数据来自多个声学监测项目，布设于战略关键位置，例如圣劳伦斯岛西侧的白令海峡与阿纳德尔海峡区域。此前部署（历时5年）与新增战略部署所产出的数据共同构成了重要基线，可用于评估环境噪声（自然与人为源）及生物活动模式，同时助力我们预测航运活动增加、资源开发与气候变化所带来的未来影响。本数据集以两个CSV格式文件呈现：NPRB1511_Deployments_metadata.csv、NPRB1511_Marine_Mammal_detections_metadata.csv。研究计算所得的结果图表收纳于与数据采集月份对应的文件夹中。本数据集由NPRB项目1511资助生成。
