Chatham Sound Hydrophone Deployed 2018-10-26

The Ocean Sonics icListen HF Hydrophone 1354 was deployed on 2018-10-26 at Chatham Sound. Chatham Sound is a sound on the North Coast of British Columbia, located between Dundas and Stephens Islands and the Tsimpsean Peninsula near Prince Rupert. 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.海洋声学公司（Ocean Sonics）生产的icListen HF型水听器1354号于2018年10月26日部署于查塔姆湾（Chatham Sound）。查塔姆湾地处不列颠哥伦比亚省北海岸，位于邓达斯岛、斯蒂芬斯岛与鲁珀特王子港附近的钦西安半岛之间。该装置为水听器（Hydrophone）：水听器是内置换能器（transducer）的声学仪器，可将水下声波转换为电信号，且能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、船舶交通活动及环境背景噪声。本次部署将设备安装于固定平台之上。此次采集所得的数据已完成归档，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，其质量保证流程及衍生数据产品均遵循行业既定操作规范。
