Patricia Bay Echosounder, Bioacoustic Deployed 2006-02-25

The ASL Zooplankton Acoustic Profiler 1008 was deployed on 2006-02-25 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浮游动物声学剖面仪1008型于2006年2月25日部署于帕特里夏湾（Patricia Bay）。帕特里夏湾地处温哥华岛南端的萨尼奇湾（Saanich Inlet）。该设备为生物声学回声测深仪。回声测深仪通过测量声学背散射信号作为替代指标，以探测水柱中的浮游动物、鱼类、气泡或其他颗粒物。回声测深仪配备一个或多个换能器，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，换能器可探测该回波并将其转换为电信号。后续通过软件即可计算水体中生物及其他物体的距离、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数字基础设施对外共享，其质量保障与衍生数据产品均遵循既定行业规范。
