Strait of Georgia Central Echosounder, Bioacoustic Deployed 2010-02-19

The ASL Acoustic Water Column Profiler 55036 was deployed on 2010-02-19 at Strait of Georgia Central. Strait of Georgia Central is a central area in the Strait of Georgia. This device is a Echosounder, Bioacoustic. Echosounders are used to measure acoustic backscatter as a proxy for detecting zooplankton, fish, bubbles or other particles in the water-column. An echosounder has one or more transducers which emit acoustic pulses at a particular frequency. When the pulses strike animals or other objects in the water, echoes are produced, which can be detected and converted by the transducers back into electrical signals. Software is then used to determine distances, sizes, concentrations and movements of organisms and other objects in the water. 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.

ASL声学水柱剖面仪55036（ASL Acoustic Water Column Profiler 55036）于2010年2月19日部署在乔治亚海峡中部（Strait of Georgia Central）。乔治亚海峡中部是乔治亚海峡的中心区域。该设备为生物声学测深仪（Bioacoustic Echosounder）。测深仪（Echosounder）通过测量声学背散射信号，作为替代指标探测水柱中的浮游动物、鱼类、气泡或其他颗粒物质。测深仪配备一个或多个换能器（transducer），可发射特定频率的声学脉冲。当脉冲撞击水中的生物或其他物体时，会产生回波，换能器可探测该回波并将其转换为电信号。后续通过软件即可确定水体中生物及其他物体的距离、尺寸、浓度与移动状态。该设备部署于固定式平台之上。本次部署获取的数据已完成归档，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，其质量管控与衍生数据产品均遵循已确立的行业规范。
