Fraser River Delta Lower Slope Fluorometer Turbidity Deployed 2013-10-23

The WET Labs ECO FLNTUSB 2472 was deployed on 2013-10-23 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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.WET Labs ECO FLNTUSB 2472型仪器于2013年10月23日部署于弗雷泽河三角洲下斜坡（Fraser River Delta Lower Slope）。该站点位于弗雷泽河三角洲下斜坡区域，水深约150米。本设备为荧光浊度仪（Fluorometer Turbidity），此类仪器可在同一海水体积内同步测量叶绿素荧光与浊度。仪器采用发光二极管（LED, light emitting diode）作为激发光源，荧光信号由与LED光源呈特定夹角的探测器接收，并通过干涉滤光片滤除散射的激发光，以甄别目标荧光信号。浊度的同步测量则通过探测另一颗LED的散射光完成，该LED的安装角度与叶绿素荧光探测的角度一致。本次部署采用固定式平台，本批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 2.0数字基础设施对外共享；数据质控与衍生数据产品的生成均遵循既定行业规范与流程。
