Fraser River Delta Lower Slope Hydrophone Deployed 2013-05-03

The Ocean Sonics icListen LF Hydrophone 203 was deployed on 2013-05-03 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.

Ocean Sonics公司的icListen LF型水听器（hydrophone）203于2013年5月3日布放于弗雷泽河三角洲下斜坡。该布放位点位于弗雷泽河三角洲下斜坡区域，水深约150米。水听器是一类搭载换能器（transducer）的装置，可将水下声波转换为电信号；作为声学仪器，其能够在数据采集过程中同步处理数据，以生成经校准的波形数据。水听器通常被用于研究海洋哺乳动物的发声行为、船舶航运活动及环境背景噪声。本次布放采用固定式平台搭载设备，采集所得数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外共享；所有数据均遵循既定规范开展质量保障工作，并生成衍生数据产品。
