ODP 1026 Current Meter Deployed 2014-05-22

The Nortek Aquadopp Current Meter 2886 was deployed on 2014-05-22 at ODP 1026. ODP 1026 is a borehole site used to pinpoint an area within Cascadia. 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.

Nortek Aquadopp 2886型海流计于2014年5月22日部署于ODP 1026站位。ODP 1026是用于精确定位卡斯卡迪亚区域内某一目标海域的钻孔监测站位。该设备为海流计，声学海流计（Acoustic Current Meters, ACM）借助多普勒效应测量海流的流速与流向。Aquadopp系列海流计的传感器探头内置3个声学换能器、倾斜传感器、温度传感器以及压力传感器。该仪器发射短脉冲声波，随后接收回波以检测音调或频率的变化，通过该音调变化即可推算海流的流速。本次部署将仪器搭载于固定式平台之上。本次采集的数据已完成归档，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，其数据质量管控与衍生数据产品均遵循既定行业规范。
