Long-term passive acoustic recording from Kerguelen deepwater mooring 2006

This dataset contains digitized passive acoustic recordings from a hydrophone connected to an autonomous recording device both moored near the sea-floor in the Southern Ocean. Recordings were digitised at a sample rate of 500 Hz and were continuous over the period of operation. The intended purpose of these recordings was to collect baseline data on the acoustic environment (i.e. underwater sound fields). Underwater sounds that were recorded include sounds generated by Antarctic sea ice, marine mammals, and man-made sounds from ships and geo-acoustic surveys. Marine mammal sounds include calls from blue, fin, humpback, and minke whales.The hydrophone was deployed on a mooring on the Kerguelen Plateau in 2006.

本数据集包含经数字化处理的被动声学录音，其采集自一台连接自主录音设备的水听器（hydrophone），该设备与水听器均锚定在南大洋的海底附近。所有录音以500 Hz的采样率完成数字化，且在设备运行周期内保持连续录制。本数据集的预设目标为收集声学环境（即水下声场）的基线数据。本次录制获取的水下声响涵盖南极海冰产生的声学信号、海洋哺乳动物的鸣叫声，以及船舶与地质声学勘测产生的人为声源。其中海洋哺乳动物的鸣叫声包括蓝鲸、长须鲸、座头鲸以及小须鲸的发声。该水听器于2006年部署在凯尔盖朗海台的锚系站位上。
