Discovery Passage Hydrophone Deployed 2020-07-15

The Ocean Sonics icListen AF Hydrophone 2523 was deployed on 2020-07-15 at Discovery Passage. Discovery Passage is a channel that is part of Inside Passage. It is located between Vancouver Island and the Discovery Islands and north of the Georgia Strait. 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 icListen AF水听器（Hydrophone）2523型号于2020年7月15日部署于发现水道（Discovery Passage）。发现水道为内海航道（Inside Passage）的组成部分，坐落于温哥华岛与发现群岛之间、乔治亚海峡以北。该设备为水听器，是一类搭载换能器（transducers）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完成处理，以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、船舶交通噪声及环境背景噪声。本次部署将设备固定于固定式平台之上。此次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数字基础设施对外公开，其质量保障工作与衍生数据产品均遵循既定规范流程。
