Patricia Bay Echosounder, Bioacoustic Deployed 2011-12-10

The ASL Zooplankton Acoustic Profiler 1006 was deployed on 2011-12-10 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1006（ASL Zooplankton Acoustic Profiler 1006）于2011年12月10日部署于帕特里夏湾（Patricia Bay）。该湾坐落于温哥华岛南端的萨尼奇湾（Saanich Inlet）内。本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，以其作为替代指标，实现对水柱内浮游动物、鱼类、气泡及其他颗粒物质的探测。该类设备配备一个或多个换能器，可按特定频率发射声学脉冲。当脉冲击中水中生物或其他物体时，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、浓度与运动状态。本次部署依托固定式平台完成。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 3.0数字基础设施对外共享；其质量控制与衍生数据产品均遵循既定行业规范。
