Endeavour North Current Meter Deployed 2012-06-19

The Nortek Aquadopp Current Meter 2809 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型2809海流计（Current Meter）于2012年6月19日部署于恩德华北海域（Endeavour North）。恩德华热液喷口区的该北部区域设有两套锚系观测系统，用于监测区域环流。本设备为海流计，声学海流计（Acoustic Current Meters, ACM）借助多普勒效应测量流速与流向。Aquadopp海流计的传感器探头集成3个声学换能器、一个倾斜传感器、温度传感器与压力传感器。该仪器发射短脉冲声波，随后监听回波以获取声频或频率变化，通过声频变化可推算海流流速。本次部署的设备搭载于固定观测平台。本批次采集的数据已通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施完成归档并对外公开，其数据质控与衍生数据产品均遵循既定行业规范生成。
