Endeavour North Current Meter Deployed 2010-09-20

The Nortek Aquadopp Current Meter A2L2554 AQD2797 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 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.

型号为A2L2554、AQD2797的Nortek Aquadopp海流计于2010年9月20日部署于恩代弗尔北海域。恩代弗尔热液喷口的北部片区设有两套锚系监测装置，用于监测区域环流。该设备为海流计，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海流计配备集成有3个声学换能器、倾斜传感器、温度传感器及压力传感器的传感器头。仪器会发射短脉冲声波，随后接收回声以测算声波的音调（或频率）变化，通过该音调变化即可推算出海流的流速。本次部署将设备安装于固定平台之上。本批次部署获取的数据集已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外共享；所有数据均遵循既定规范完成质量管控，并产出符合标准的衍生数据产品。
