Douglas Channel Fluorometer Turbidity Deployed 2017-04-06

The WET Labs ECO FLNTUSB 2472 was deployed on 2017-04-06 at Douglas Channel. Douglas Channel is one of the principal inlets of the British Columbia coast. This device is a Fluorometer Turbidity. Fluorometer Turbidity instruments measure chlorophyll fluorescence and turbidity within the same volume of seawater. The instrument uses a light emitting diode (LED) to provide an excitation source. The fluoresced light is received by a detector at a particular angle from the LED source, and uses an interference filter to discriminate against scattered excitation light. Turbidity is measured at the same time, by detecting scattered light from a LED, which is positioned at the same angle as the chlorophyll fluorescence. 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.

WET Labs公司的ECO FLNTUSB 2472型设备于2017年4月6日部署于道格拉斯海峡（Douglas Channel）。道格拉斯海峡是不列颠哥伦比亚省沿岸的主要入海口之一。该设备为荧光浊度测量仪（Fluorometer Turbidity），可在同一海水体积内同步测量叶绿素荧光度与浊度。该仪器采用发光二极管（Light Emitting Diode，LED）作为激发光源，荧光信号由与该激发LED光源成特定夹角的检测器接收，并通过干涉滤光片滤除散射的激发光以甄别有效信号。浊度则通过检测来自另一颗LED的散射光完成测量，该LED的安装角度与叶绿素荧光检测的角度一致。本次部署搭载于固定式平台，所获取的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施对外提供，且遵循既定规范完成了质量保证与衍生数据产品的制备。
