CCGS John P. Tully Acoustic Doppler Current Profiler 75 kHz Deployed 2018-09-28

The RDI Ocean Surveyor ADCP 75 kHz (SN 1568) was deployed on 2018-09-28 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 Acoustic Doppler Current Profiler 75 kHz. Acoustic Doppler Current Profilers (ADCP) are hydroacoustic instruments, similar to sonars. ADCPs measure current speed and direction at multiple predetermined depths simultaneously. ADCPs use the Doppler effect of sound waves that are scattered by particles in seawater over a depth range. 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.

序列号1568的RDI Ocean Surveyor型75kHz声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP）于2018年9月28日部署于加拿大海岸警卫队“约翰·P·塔利”号（CCGS John P. Tully）。加拿大海岸警卫队舰船（Canadian Coast Guard Ship，CCGS）“约翰·P·塔利”号由加拿大海岸警卫队所有并运营。该设备为75kHz声学多普勒流速剖面仪（ADCP）。声学多普勒流速剖面仪（ADCP）是一类与声呐类似的水声仪器，可同时测量多个预设深度处的海流流速与流向。ADCP利用声波被海水内颗粒物散射产生的多普勒效应，在指定深度范围内开展流速流向测量。本次部署搭载于移动平台。此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数字基础设施对外公开提供，其质量保障流程及衍生数据产品均遵循行业既定规范。
