Endeavour South Acoustic Doppler Current Profiler 75 kHz Deployed 2019-09-20

The RDI Workhorse Long Ranger ADCP 75 kHz (17432) was deployed on 2019-09-20 at Endeavour South. This south section of the Endeavour Hydrothermal Vents includes two moorings to monitor the regional circulation. 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 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.

RDI Workhorse Long Ranger 75 kHz声学多普勒流速剖面仪（编号17432）于2019年9月20日部署在奋进号南部区域。奋进号热液喷口的南部区域设有两个系泊设备，用于监测区域环流。

该设备为75 kHz声学多普勒流速剖面仪（Acoustic Doppler Current Profiler）。声学多普勒流速剖面仪（ADCP）是一种水声仪器，与声呐类似。ADCP可同时测量多个预设深度处的海流速度和方向。ADCP利用声波在一定深度范围内被海水中颗粒散射产生的多普勒效应进行测量。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。
