Patricia Bay Echosounder, Bioacoustic Deployed 2018-09-30

The ASL AZFP Echosounder 55167 was deployed on 2018-09-30 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 AZFP回声测深仪（Echosounder）55167于2018年9月30日部署于帕特里夏湾（Patricia Bay）。帕特里夏湾地处温哥华岛（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）。回声测深仪通过测量声学背散射信号，作为检测水柱中浮游动物、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体及其他物体的距离、尺寸、浓度与移动情况。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数字基础设施对外提供，其质量保证与衍生数据产品均遵循既定行业规范。
