Minas Passage Acoustic Doppler Current Profiler 400 kHz Deployed 2015-09-29

The Nortek AWAC AST 400 kHz 2226 was deployed on 2015-09-29 at Minas Passage. The Minas Basin is an inlet of the Bay of Fundy and a sub-basin of the Fundy Basin located in Nova Scotia, Canada. This device is a Acoustic Doppler Current Profiler 400 kHz. Acoustic Doppler Current Profilers 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.

Nortek AWAC AST 400 kHz 2226型设备于2015年9月29日部署在米纳斯水道（Minas Passage）。米纳斯湾（Minas Basin）是芬迪湾（Bay of Fundy）的入海口海湾，同时也是位于加拿大新斯科舍省的芬迪盆地（Fundy Basin）的次级盆地。该设备为400 kHz声学多普勒流速剖面仪（Acoustic Doppler Current Profiler，ADCP）。声学多普勒流速剖面仪是一类与声呐相似的水声探测仪器，可同时在多个预设深度处测量水流速度与流向。此类设备利用声波的多普勒效应（Doppler effect），通过海水中悬浮颗粒物对声波的散射作用，获取指定深度范围内的水流数据。本次部署将该设备搭载于固定平台之上。本次部署采集的相关数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外公开共享，且遵循既定行业规范完成了质量管控与衍生数据产品的生成。
