Patricia Bay Echosounder, Bioacoustic Deployed 2009-09-30

The SciFish Broadband Echosounder SN 0075 was deployed on 2009-09-30 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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

SciFish宽带回声测深仪（SciFish Broadband Echosounder）序列号0075于2009年9月30日部署于帕特里夏湾（Patricia Bay）。帕特里夏湾位于温哥华岛南端的萨尼奇湾（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（acoustic backscatter）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。当脉冲击中水中的生物或其他物体时，会产生回波，换能器可检测该回波并将其转换为电信号。随后通过软件分析，可计算水体中生物及其他物体的距离、尺寸、浓度与运动状态。本次部署搭载于固定平台。此次部署产生的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外共享，所有数据均遵循既定规范开展质量管控，并生成符合标准的衍生数据产品。
