Acoustic Recordings of Killer Whales in Prince William Sound and Kenai Fjords, 2012-2021, Gulf Watch Alaska Pelagic Component

This dataset includes recordings of killer whale (Orca) vocalizations made during Spring, Summer, and Fall from 2012-2021 in Prince William Sound and Kenai Fjords. As recordings were secondary to photo-identification, they were made opportunistically, or when behavior was observed that would be better documented with recordings.Recordings were made with Offshore Acoustics and Hi-Tec hydrophones (3-7 meters depth), Tascam DR100 Mark II and Marantz PMD671 recording devices from research vessels of 12 meters or less, with no generator noise. Recordings are converted from wav to the flac format and have not been otherwise processed. Recordings are grouped together in .zip files by year, with individual files labelled with a time and/or date stamp. in yyyymmdd format. Beginning in 2016, the time is also included the file name, yyyymmdd_hhmm. However, there may still be files unlabeled by time, which are appended automatically with a file number, ie. _0162. When possible, the pod is included in the file or directory name, but these labels are for reference and may not be inclusive of all animals present. These data are part of the Gulf Watch Alaska (GWA), Pelagic Component of the Exxon Valdez Oil Spill Trustee Council, project numbers 12120114-M, 13120114-M, 14120114-M, 15120114-M and 16120114-M. Gulf Watch Alaska is the long-term ecosystem monitoring program of the Exxon Valdez Oil Spill Trustee Council for the marine ecosystem affected by the 1989 oil spill.

本数据集包含2012年至2021年春、夏、秋三季，在威廉王子湾（Prince William Sound）与基奈峡湾（Kenai Fjords）采集的虎鲸（Orca）发声录音。鉴于照片识别为本次工作的核心任务，录音仅作为辅助手段，因此本次录音均为机会性采集，或在观察到需通过录音更全面记录的行为时开展。本次录音采用Offshore Acoustics与Hi-Tec品牌水听器（部署深度3~7米），搭配Tascam DR100 Mark II及Marantz PMD671录音设备，使用长度不超过12米的研究船进行采集，采集过程无发电机噪音干扰。所有录音均从WAV格式转换为FLAC格式，未经过其他后期处理。录音按年份打包为ZIP压缩文件，单个文件以时间或/和日期戳命名，格式为yyyymmdd。2016年起，文件名中新增时间信息，格式为yyyymmdd_hhmm。但仍存在未标注时间的文件，此类文件会自动追加文件编号，如_0162。若条件允许，鲸群（pod）信息会被包含在文件或目录名称中，但此类标签仅作参考，未必涵盖所有在场个体。本数据集隶属于阿拉斯加海湾观测计划（Gulf Watch Alaska, GWA）旗下埃克森瓦尔迪兹石油泄漏信托委员会远洋组分项目，项目编号分别为12120114-M、13120114-M、14120114-M、15120114-M及16120114-M。阿拉斯加海湾观测计划是埃克森瓦尔迪兹石油泄漏信托委员会针对1989年受漏油事件影响的海洋生态系统开展的长期生态系统监测项目。
