Barkley Canyon Mid-East Fluorometer Turbidity Deployed 2013-05-17

The WET Labs ECO FLNTURTD 2973 was deployed on 2013-05-17 at Barkley Canyon Mid-East. Barkley Canyon Mid-East is a location in Barkley Canyon near a canyon wall. At this location, benthic processes, biodiversity, and sediment dynamics are observed. 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 FLNTURTD 2973 于2013年5月17日部署于巴克利峡谷中东部（Barkley Canyon Mid-East）。该区域地处巴克利峡谷内、临近峡谷岩壁，为底栖过程、生物多样性与沉积物动力学的观测位点。本设备为荧光浊度仪（Fluorometer Turbidity），可在同一海水体积内同步测定叶绿素荧光与浊度。设备以发光二极管（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。浊度则通过探测来自LED的散射光同步测得，该LED的安装夹角与叶绿素荧光探测夹角一致。本设备部署于固定式平台。本次部署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，其质量管控与衍生数据产品均遵循既定行业规范。
