Barkley Canyon Mid-East Fluorometer Turbidity Deployed 2012-06-02

The WET Labs ECO FLNTURTD 1087 was deployed on 2012-06-02 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 1087 设备于2012年6月2日部署于巴克利峡谷中东部（Barkley Canyon Mid-East）。该点位为巴克利峡谷内临近峡谷岩壁的区域，此处开展底栖过程、生物多样性与沉积物动力学相关观测研究。本设备为荧光计浊度仪（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，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。浊度测量则通过探测同一LED光源的散射光完成，该LED的安装角度与叶绿素荧光探测的角度保持一致。本次部署依托固定式平台开展，所获数据已完成归档，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规范完成质量管控，并配套提供衍生数据产品。
