Barkley Canyon Mid-West Sediment Trap Deployed 2014-05-12

The McLane Parflux MK78H-21 Sediment Trap (SN 12294-01) was deployed on 2014-05-12 at Barkley Canyon Mid-West. Barkley Canyon Mid-West 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 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.

McLane Parflux MK78H-21沉积物捕获器（序列号SN 12294-01）于2014年5月12日部署在巴克利峡谷中西部。
巴克利峡谷中西部位于巴克利峡谷内靠近峡谷壁处，在此地点可观测底栖过程（benthic processes）、生物多样性及沉积物动力学（sediment dynamics）。
该装置为沉积物捕获器（Sediment Trap）。沉积物捕获器采用锥形收集器引导沉降颗粒进入一组样品瓶。仪器旋转时可收集独立瓶样；沉积物捕获器可由用户远程触发或按预设时间表启动。
沉积物捕获器记录每次采样事件的操作条件，包括采样日期、时间及温度。仪器回收后，样品将在实验室中分析随时间变化的颗粒通量（particle flux）及组成。
该装置部署于固定平台；本次部署的数据已归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 3.0数字基础设施开放获取，其质量保证及衍生数据产品均遵循既定规范。
