Patricia Bay Echosounder, Bioacoustic Deployed 2011-04-19

The ASL Acoustic Water Column Profiler 5016 was deployed on 2011-04-19 at Patricia Bay. Patricia Bay is located in the Saanich Inlet, on the southern tip of Vancouver Island. 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5016（ASL Acoustic Water Column Profiler 5016）于2011年4月19日部署于帕特里夏湾（Patricia Bay）。帕特里夏湾位于温哥华岛（Vancouver Island）南端的萨尼奇湾（Saanich Inlet）内。该设备为生物声学回声测深仪（Bioacoustic Echosounder），此类设备通过测量声学背散射（acoustic backscatter）信号，作为检测水柱（water-column）内浮游动物（zooplankton）、鱼类、气泡或其他颗粒物的替代指标。回声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；当脉冲击中水体中的动物或其他物体时，会产生回波，换能器可检测该回波并将其转换为电信号。随后通过软件计算水体中生物及其他物体的距离、尺寸、浓度与运动状态。本次部署依托固定式平台完成，所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，其质量控制与衍生数据产品均遵循既定行业规范。
