Endeavour North Acoustic Doppler Current Profiler 75 kHz Deployed 2012-06-19

The RDI Workhorse Long Ranger ADCP 75 kHz (16511) was deployed on 2012-06-19 at Endeavour North. This north 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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

编号为16511的RDI Workhorse Long Ranger型75kHz声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP）于2012年6月19日在恩德华北（Endeavour North）海域完成部署。恩德华热液喷口区的北部区域设有两套锚系观测装置，用于监测区域环流。声学多普勒流速剖面仪是一类与声呐原理相似的水声仪器，可同时测量多个预设深度处的海流流速与流向。该设备利用声波段范围内海水中颗粒物散射声波的多普勒效应开展测量。本次部署将该设备搭载于固定平台之上。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 2.0数字基础设施对外共享；所有数据均遵循既定规范开展质量管控，并提供衍生数据产品。
