Endeavour North Current Meter Deployed 2010-09-20

The Nortek Aquadopp Current Meter A2L2492 AQD2761 was deployed on 2010-09-20 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.

Nortek Aquadopp流速仪（型号A2L2492 AQD2761）于2010年9月20日部署在奋进号北部。奋进号热液喷口的北部区域设有两个系泊设备，用于监测区域环流。

该设备为流速仪。声学流速仪（ACM）利用多普勒效应测量水流速度与方向。Aquadopp流速仪的传感器探头包含3个声学换能器、1个倾斜传感器、1个温度传感器及1个压力传感器。仪器发射短声波脉冲，随后接收回波以测量音调或频率的变化，通过音调变化可确定水流速度。

该仪器部署于固定平台。

本次部署产生的数据已存档，并通过加拿大海洋网络的Oceans 2.0数字基础设施开放获取；其质量保证与衍生数据产品均遵循既定规范。
