Strait of Georgia East Echosounder, Bioacoustic Deployed 2013-03-03

The ASL Zooplankton Acoustic Profiler 1008 was deployed on 2013-03-03 at Strait of Georgia East. Strait of Georgia East refers to an eastern area of the Strait of Georgia. 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（ASL Zooplankton Acoustic Profiler 1008）于2013年3月3日部署在乔治亚海峡东部（Strait of Georgia East），该区域指乔治亚海峡的东部海域。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反向散射信号，以此作为替代指标来检测水柱中的浮游动物、鱼类、气泡及其他颗粒物。回声测深仪配备一个或多个换能器（transducers），可发射特定频率的声学脉冲。当脉冲接触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。后续通过软件即可测算水体中生物及其他物体的距离、尺寸、浓度与移动状态。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，其数据质量保障流程与衍生数据产品均遵循既定行业规范。
