Fraser River Delta Lower Slope Hydrophone Deployed 2017-11-04

The Ocean Sonics icListen AF Hydrophone 2523 was deployed on 2017-11-04 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 AF型水听器（Hydrophone）2523于2017年11月4日部署于弗雷泽河三角洲下斜坡海域。该部署站点位于弗雷泽河三角洲下斜坡区域，海域水深约150米。该设备为水听器。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。其属于声学监测仪器，能够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。水听器通常被用于研究海洋哺乳动物的发声行为、船舶通航活动以及水下环境噪声。该设备搭载于固定式平台之上。本次部署采集得到的数据已完成归档，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；数据的质量保障与衍生数据产品的生成均遵循既定行业规范与操作流程。
