Discovery Passage Hydrophone Deployed 2022-01-28

The Ocean Sonics icListen HF Hydrophone 1350 was deployed on 2022-01-28 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 3.0 digital infrastructure, with quality assurance and derived data products following established practices.

2022年1月28日，Ocean Sonics icListen HF型水听器1350（Hydrophone）部署于发现海峡（Discovery Passage）。发现海峡是内航道（Inside Passage）的组成部分，坐落于温哥华岛（Vancouver Island）与发现群岛（Discovery Islands）之间、乔治亚海峡（Georgia Strait）北侧。该设备为水听器（Hydrophone），此类装置搭载换能器（transducer），可将水下声波转换为电信号，属于声学仪器；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。水听器通常被用于海洋哺乳动物发声行为研究、船舶交通监测以及环境背景噪声分析等场景。本次部署将该设备固定于固定式平台之上，此次采集的数据已完成存档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外提供；其质量保障流程与衍生数据产品均遵循行业既定规范。
