Cambridge Bay Fluorometer Turbidity Deployed 2019-07-31

The WET Labs ECO FLNTUS 3923 was deployed on 2019-07-31 at Cambridge Bay. Cambridge Bay is located on Victoria Island in the Kitikmeot Region of Nunavut, Canada. 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 FLNTUS 3923型设备于2019年7月31日部署于加拿大努纳武特地区基蒂克美奥特区维多利亚岛的剑桥湾。该设备为荧光计-浊度计（Fluorometer Turbidity），此类仪器可在同一海水采样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，荧光信号由与LED光源成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实现信号甄别。浊度测量同步开展：通过探测同一LED光源的散射光完成，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平台，采集所得数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外开放共享，其质量管控与衍生数据产品均遵循行业既定实践规范。
