Fraser River Delta Lower Slope Fluorometer Turbidity Deployed 2013-05-04

The WET Labs ECO FLNTUSB 2473 was deployed on 2013-05-04 at Fraser River Delta Lower Slope. This site is located on the lower slope of the Fraser River delta, where depth is approximately 150 metres. 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 2473设备于2013年5月4日部署于弗雷泽河三角洲下斜坡（Fraser River Delta Lower Slope）。该观测站位位于弗雷泽河三角洲下斜坡区域，水深约150米。本设备为荧光计浊度仪（Fluorometer Turbidity），可在同一海水体积内同步测量叶绿素荧光与浊度。该设备采用发光二极管（Light Emitting Diode，LED）作为激发光源，荧光经与激发光源呈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；浊度则通过检测另一发光二极管的散射光实现同步测量，该发光二极管的安装角度与叶绿素荧光检测所用的光源夹角一致。该设备部署于固定式观测平台。本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开展质量管控，并衍生了配套的数据产品。
