Strait of Georgia Central Fluorometer Turbidity Deployed 2021-09-28

The WET Labs ECO FLNTUSB 2472 was deployed on 2021-09-28 at Strait of Georgia Central. Strait of Georgia Central is a central area in the Strait of Georgia. 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 ECO FLNTUSB 2472 型观测设备于2021年9月28日部署于乔治亚海峡中部（Strait of Georgia Central）。乔治亚海峡中部为乔治亚海峡（Strait of Georgia）的中心水域区域。该设备为荧光计浊度仪（Fluorometer Turbidity），此类仪器可在同一体积的海水中同步测量叶绿素荧光强度与浊度。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消除背景干扰。浊度测量则通过检测另一颗LED的散射光实现同步采集，该LED的安装角度与叶绿素荧光检测的角度完全一致。本次部署采用固定式观测平台。本次采集的相关数据已完成归档，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；所有数据均遵循既定科研规范完成质量管控，并生成了对应的衍生数据产品。
