Endeavour South Current Meter Deployed 2012-06-15

The Nortek Aquadopp Current Meter A2L2498 AQD2760 was deployed on 2012-06-15 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 metres 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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

诺泰克（Nortek）Aquadopp型海流计A2L2498、AQD2760于2012年6月15日部署在恩德华南（Endeavour South）海域。恩德华热液喷口（Endeavour Hydrothermal Vents）的南侧区域设有两套锚系监测装置，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）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了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。该仪器先发射短声波脉冲，随后接收其回波以检测音调（频率）的变化量，通过该变化量即可反演海流的流速。本次部署依托固定式平台完成。本次部署获取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数字基础设施对外共享，所有数据均遵循既定规范完成质量管控，并产出配套衍生数据产品。
