Fraser River Delta Lower Slope Hydrophone Deployed 2014-03-08

The JASCO M8E-51C35dBV Hydrophone 740 was deployed on 2014-03-08 at Fraser River Delta Lower Slope. This site is located on the lower slope of the Fraser River delta, where depth is approximately 150 metres. This device is a Hydrophone. Hydrophones are devices containing transducers that convert underwater sound waves into electrical signals. They are acoustic instruments that can process data while they are being collected to produce calibrated waveform data. Hydrophones are typically used to study vocalizations of marine mammals, ship traffic and ambient noise. It was deployed on a fixed platform. Data from this deployment were archived and made available through Ocean Networks Canada's Oceans 2.0 digital infrastructure, with quality assurance and derived data products following established practices.JASCO M8E-51C35dBV水听器（Hydrophone）740于2014年3月8日部署于弗雷泽河三角洲下斜坡站位。该站位地处弗雷泽河三角洲下斜坡区域，水深约150米。本设备为水听器，属于搭载换能器（transducer）的声学仪器，可将水下声波转换为电信号，并在数据采集过程中实时处理数据，生成经过校准的波形数据。水听器通常被应用于海洋哺乳动物发声行为研究、船舶通航噪声监测以及环境背景噪声分析领域。本次部署的水听器搭载于固定平台之上，采集所得数据已通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施完成存档并对外开放，其质量保障与衍生数据产品均遵循既定行业规范。
