Barkley Upper Slope Hydrophone Deployed 2009-07-26

The Naxys Hydrophone 01428 (S/N 003) was deployed on 2009-07-26 at Barkley Upper Slope. Upper Slope is a location within Barkley Canyon, which is located on the upper continental slope. 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.

Naxys水听器（Hydrophone）01428（S/N 003）于2009年7月26日部署于巴克利上斜坡（Barkley Upper Slope）。巴克利上斜坡为巴克利峡谷（Barkley Canyon）内的一处区域，而巴克利峡谷地处大陆架上斜坡（upper continental slope）地带。
该设备为水听器，其内置换能器（transducer），可将水下声波转换为电信号，属于可在数据采集过程中同步处理，以生成校准后波形数据的声学仪器。
水听器通常被应用于海洋哺乳动物发声行为、船舶航行噪声以及环境背景噪声的相关研究。
本次部署采用固定式平台搭载该设备。本批次采集的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外开放获取，其质量保证流程与衍生数据产品均遵循行业既定规范。
