Endeavour North Current Meter Deployed 2012-06-19

The Nortek Aquadopp Current Meter A2L2560 (AQD 2811) 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 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 A2L2560（AQD 2811）型海流计于2012年6月19日部署于恩代尔北海域。恩代尔热液喷口区的北部区域布设了两套锚系观测装置，用于监测区域环流。本设备属于海流计范畴，声学海流计（Acoustic Current Meters, ACM）通过多普勒效应测量海流的流速与流向。Aquadopp型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、一个温度传感器与一个压力传感器。该仪器先发射短脉冲声波，随后接收回波以检测频率（音调）的变化，通过该频率偏移量即可推算海流流速。本次部署的载体为固定式平台。本次采集的数据集已完成归档，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行业规范完成质量管控，并产出了配套的衍生数据产品。
