Patricia Bay Echosounder, Bioacoustic Deployed 2012-02-26

The ASL Zooplankton Acoustic Profiler 1007 was deployed on 2012-02-26 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1007于2012年2月26日部署在帕特里夏湾。帕特里夏湾位于温哥华岛南端的萨尼奇湾内。该设备为生物声学回声探测仪（Echosounder）。回声探测仪通过测量声学反向散射来间接探测水柱中的浮游动物、鱼类、气泡或其他颗粒物。回声探测仪配备一个或多个换能器（transducer），可发射特定频率的声学脉冲。当脉冲撞击水中的动物或其他物体时会产生回声，回声可被换能器检测并转换回电信号。随后通过软件计算水中生物及其他物体的距离、大小、浓度和运动状态。该设备部署于固定平台上。此次部署产生的数据已归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施开放获取，其质量保证和衍生数据产品均遵循既定规范。
