Barkley Canyon Axis Sediment Trap Deployed 2018-08-01

The McLane Sediment Trap 78H-21 (S/N 13041-01) was deployed on 2018-08-01 at Barkley Canyon Axis. Barkley Canyon Axis is located within Barkley Canyon, where benthic processes, biodiversity, 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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.McLane沉积物捕集器（Sediment Trap）78H-21（序列号S/N 13041-01）于2018年8月1日部署于巴克利峡谷轴（Barkley Canyon Axis）。巴克利峡谷轴地处巴克利峡谷（Barkley Canyon）范围内，该区域针对底栖过程、生物多样性及沉积物动力学开展观测研究。本设备为沉积物捕集器：其采用锥形捕集结构，将沉降颗粒物引导至一组样品瓶中；随着仪器旋转，可依次收集各样品瓶内的样品。沉积物捕集器可由用户远程触发启动，或按照预设采样计划自动运行。该设备会记录每次采样事件的运行工况，包括采样日期、时间以及采样过程中的温度数据。待仪器回收后，科研人员将在实验室中对样品进行分析，以测定其随时间变化的颗粒通量与组分特征。本次部署搭载于固定平台之上。本批次部署产生的数据已完成归档，并通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施对外公开共享，其质量管控流程与衍生数据产品均遵循既定行业规范。
