Endeavour South Current Meter Deployed 2023-07-09

The Nortek Aquadopp Current Meter A3L9188 AQD14218 was deployed on 2023-07-09 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A3L9188 AQD14218于2023年7月9日部署于恩迪弗尔南（Endeavour South）海域。恩迪弗尔热液喷口区的南部片区设有两套锚系观测系统，用于监测区域环流特征。该设备属于海流计范畴，声学海流计（Acoustic Current Meters, ACM）依托多普勒效应测量海流的流速与流向。Aquadopp海流计的传感器探头集成3个声学换能器、倾斜传感器、温度传感器及压力传感器。该仪器先发射短声脉冲，随后接收回波以检测频率（音调）的变化，基于该频移量即可推算海流流速。本次部署搭载于固定观测平台。本批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共享；所有数据均遵循行业既定规范完成质量管控，并产出配套衍生数据产品。
