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

The JASCO M8E-51C35dBV Hydrophone 742 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 3.0 digital infrastructure, with quality assurance and derived data products following established practices.

JASCO M8E-51C35dBV型水听器（Hydrophone）742于2014年3月8日布放于弗雷泽河三角洲下斜坡区域。该站位地处弗雷泽河三角洲下斜坡，水深约150米。该设备为水听器，是集成换能器（transducer）的装置，可将水下声波转换为电信号；作为声学仪器，其可在数据采集过程中同步处理数据，生成经过校准的波形数据。水听器通常被用于研究海洋哺乳动物的发声行为、船舶航运噪声及环境背景噪声。该设备搭载于固定式平台完成布放，本次布放获取的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外共享；数据的质量保证与衍生数据产品生产均遵循既定行业规范。
