CCGS John P. Tully Echosounder, Bioacoustic Deployed 2016-04-28

The Kongsberg Simrad EK60 Tully 01 was deployed on 2016-04-28 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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.康斯博（Kongsberg）西姆拉德（Simrad）EK60 Tully 01型设备于2016年4月28日部署于加拿大海岸警卫队舰船（Canadian Coast Guard Ship, CCGS）约翰·P·特利号。该舰船由加拿大海岸警卫队所有并运营。本设备为生物声学（Bioacoustic）回声测深仪（Echosounder），其通过测量声学背散射信号，作为探测水体中浮游动物、鱼类、气泡及其他颗粒物质的替代指标。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；当脉冲接触水体中的动物或其他物体时，会产生回波，换能器可探测该回波并将其转换为电信号，后续通过软件可计算水体中生物及其他物体的距离、尺寸、浓度与移动状态。本次部署搭载于移动平台，所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 2.0数字基础设施对外共享，其数据质控流程与衍生数据产品均遵循行业既定规范。
