Endeavour South Current Meter Deployed 2019-09-20

The Nortek Aquadopp Current Meter A2L2499 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 Current Meter. Acoustic Current Meters (ACM) measure current speed and direction, using the Doppler Effect. Aquadopp current meters have a sensor head that contains 3 acoustic transducers, a tilt sensor, a temperature sensor and a pressure sensor. The instrument transmits a short pulse of sound, and then listens to its echo to measure the change in pitch or frequency. The change in pitch can determine the velocity of the current. 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.

诺泰克（Nortek）Aquadopp海流计A2L2499于2019年9月20日部署于恩德华南（Endeavour South）海域。恩德华热液喷口（Endeavour Hydrothermal Vents）的南部区域设有两套锚系装置，用于监测区域环流。该设备属于海流计范畴。声学海流计（Acoustic Current Meters, ACM）利用多普勒效应（Doppler Effect）测量海流的流速与流向。Aquadopp海流计配备集成有3个声学换能器、一个倾斜传感器、一个温度传感器及一个压力传感器的探头单元。仪器通过发射短声波脉冲并接收回波，测量音调或频率的变化，进而推算海流流速。该设备部署于固定式平台之上。本次部署采集的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外开放；数据质量控制与衍生数据产品的生成均遵循既定行业规范。
