Fraser River Delta Lower Slope Fluorometer Turbidity Deployed 2014-03-09

The WET Labs ECO FLNTUSB 2473 was deployed on 2014-03-09 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 2473 型仪器于2014年3月9日布放于弗雷泽河三角洲下斜坡站位。该站位地处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），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（Light Emitting Diode，LED）作为激发光源：探测器将在与LED光源成特定夹角的位置接收荧光信号，并通过干涉滤光片滤除散射激发光的干扰。浊度测量同步开展，通过探测同一LED发射光的散射光实现量化，该LED的安装角度与叶绿素荧光探测角度完全一致。本次布放搭载于固定观测平台，采集数据已完成归档，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；所有数据均遵循既定行业规范开展质量控制，并可获取对应的衍生数据产品。
