Upper Slope South Sediment Trap Deployed 2012-05-30

The McLane Parflux MK78H-21 Sediment Trap (SN 12294-02) was deployed on 2012-05-30 at Upper Slope South. Upper Slope South is a location within Barkley Canyon, which is located on the upper continental slope. This device is a Sediment Trap. Sediment traps use a conical-shaped trap to guide settling particles into a set of sample bottles. Separate bottle samples are collected as the instrument is rotated. Sediment traps can be remotely triggered by a user or on a set schedule. Sediment traps record operational conditions including the sample date, time, and temperature during each sampling event. Upon instrument recovery, the samples are analyzed in a lab for particle flux and composition over time. 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.

本次研究涉及的麦克莱恩Parflux MK78H-21型沉积物捕集器（Sediment Trap，序列号SN 12294-02）于2012年5月30日部署在南上部斜坡（Upper Slope South）站位。南上部斜坡是位于大陆架上部斜坡的巴克利峡谷（Barkley Canyon）内的一处区域。该设备为沉积物捕集器，其通过锥形捕集结构引导沉降颗粒物进入一组采样瓶，随仪器旋转可依次采集不同采样瓶内的样品。沉积物捕集器支持用户远程触发，或按照预设周期自动启动采样，且会记录每次采样事件的采样日期、时间及采样过程中的温度等运行工况。设备回收后，实验室将对样品开展分析，以获取随时间变化的颗粒物通量与组分特征。本次部署搭载于固定平台，此次采集的数据已通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施存档并对外开放共享，相关数据的质量控制及衍生数据产品均遵循既定行业规范流程。
