Beaked Whale acoustic detections in the Gulf of Mexico, 2010 - 2013

This dataset contains a subset of passive acoustic data used to identify the acoustic signatures of four species of beaked whale in the Gulf of Mexico. The four species are Cuvier’s beaked whale, Gervais’ beaked whale, Blainville’s beaked whale, and a sound believed to be a beaked whale but of an unidentified species that we designate as “Beaked Whale Gulf ” (BWG). The data were collected at five locations in the Gulf of Mexico: Green Canyon, Mississippi Canyon, Dry Tortugas, Main Pass, and DeSoto Canyon. However, detections of beaked whales only occurred at Green Canyon, Mississippi Canyon, and Dry Tortugas. The acoustic signatures were used to estimate densities of beaked whales in the Gulf of Mexico. Results of the analysis were published in the paper Passive acoustic monitoring of beaked whale densities in the Gulf of Mexico (Hildebrand et al. 2015, DOI: 10.1038/srep16343). The data are stored in a Tethys temporal-spatial metadata database and must be used in conjunction with another programing environment. Sample source xwav audio files, and installation files and documentation for Tethys are included with the beaked whale acoustic data.

本数据集包含用于识别墨西哥湾四种喙鲸声学特征的被动声学数据子集。这四个物种分别为居维叶喙鲸（Cuvier’s beaked whale）、热尔韦斯喙鲸（Gervais’ beaked whale）、布兰维尔喙鲸（Blainville’s beaked whale），以及一种被认定为喙鲸但物种未明确的声学信号，我们将其命名为"墨西哥湾喙鲸（Beaked Whale Gulf，简称BWG）"。数据采集自墨西哥湾的五个区域：格林峡谷（Green Canyon）、密西西比峡谷（Mississippi Canyon）、德赖托图格斯群岛（Dry Tortugas）、梅恩帕斯（Main Pass）以及德索托峡谷（DeSoto Canyon）。但仅在格林峡谷、密西西比峡谷与德赖托图格斯群岛区域检测到了喙鲸信号。上述声学特征被用于估算墨西哥湾喙鲸的种群密度。相关分析结果已发表于论文《墨西哥湾喙鲸密度的被动声学监测》（Hildebrand 等人，2015年，DOI: 10.1038/srep16343）。本数据集存储于泰西斯时空元数据库（Tethys temporal-spatial metadata database）中，且需配合其他编程环境使用。本喙鲸声学数据配套包含示例xwav音频文件、泰西斯数据库的安装文件与使用文档。
