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.麦克莱恩沉积物捕集器78H-21（序列号：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区域，该区域开展底栖过程、生物多样性及沉积物动力学相关观测。本设备为沉积物捕集器（Sediment Trap），通过锥形捕集结构将沉降颗粒物引导至一组采样瓶中，仪器旋转时可采集独立的瓶内样品。沉积物捕集器支持用户远程触发，或按预设计划启动采样。每次采样事件均会记录采样日期、时间及采样期间的温度等运行参数。设备回收后，实验室将对样品开展分析，以获取颗粒通量及其随时间的组成变化特征。本次部署采用固定式平台。本批次部署产生的数据已完成存档，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，相关数据已按照既定规范完成质量管控，并生成了标准衍生数据产品。
