Barkley Canyon Hydrophone Deployed 2019-09-17

The Ocean Sonics icListen HF Hydrophone 1252 was deployed on 2019-09-17 at Barkley Canyon. Barkley Canyon is a submarine canyon located on the continental shelf and slope break. Features include exposed gas hydrates and their associated ecosystems. Accumulation and movement of sediment, upwelling, and plankton blooms are studied in this area. 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.

Ocean Sonics公司生产的icListen HF型水听器1252于2019年9月17日部署于巴克利峡谷（Barkley Canyon）。巴克利峡谷是一处位于大陆架与大陆坡折带的海底峡谷，区域内具有裸露的天然气水合物及其伴生生态系统等特征。该区域的研究主题包括沉积物的堆积与运移、上升流及浮游植物水华现象。该设备为水听器（hydrophone），水听器是一类内置换能器的设备，可将水下声波转换为电信号；作为声学仪器，水听器可在数据采集过程中实时处理数据，以生成经过校准的波形数据。水听器通常被应用于海洋哺乳动物发声研究、船舶航运监测以及环境背景噪声分析。本次部署的水听器搭载于固定式平台。本次部署采集的相关数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外共享，其质量管控与衍生数据产品的生成均遵循行业既定规范。
