CCGS John P. Tully Echosounder, Bioacoustic Deployed 2020-03-01

The Kongsberg Simrad EK60 Tully 01 was deployed on 2020-03-01 on CCGS John P. Tully. The Canadian Coast Guard Ship (CCGS) John P. Tully is owned and operated by the Canadian Coast Guard. 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 mobile 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.

Kongsberg Simrad EK60 Tully 01设备于2020年3月1日部署在CCGS John P. Tully号上。加拿大海岸警卫队船只（Canadian Coast Guard Ship，CCGS）John P. Tully号由加拿大海岸警卫队拥有并运营。该设备为生物声学回声测深仪（Echosounder, Bioacoustic）。回声测深仪通过测量声学反向散射，将其作为检测水柱中浮游动物、鱼类、气泡或其他颗粒物的间接手段。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脉冲；当脉冲撞击水中生物或其他物体时产生回声，换能器可检测并将其转换回电信号。随后通过软件分析确定水中生物及物体的距离、尺寸、浓度与运动状态。该设备部署于移动平台，此次部署的数据已完成存档，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，其质量保证与衍生数据产品均遵循既定规范。
