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 2.0 digital infrastructure, with quality assurance and derived data products following established practices.

麦克莱恩Parflux MK78H-21型沉积物捕集器（序列号SN 12294-01）于2014年5月12日部署在巴克利峡谷中西部区域。该区域坐落于巴克利峡谷内，毗邻峡谷岩壁，是开展底栖过程、生物多样性及沉积物动力学研究的观测点位。本设备为沉积物捕集器（Sediment Trap），其采用锥形捕集结构将沉降颗粒导引至一组采样瓶内；随设备旋转可分别采集各采样瓶中的样品。沉积物捕集器支持用户远程触发，或按照预设计划自动启动采样，每次采样过程中均会记录采样日期、时间及采样时的温度等运行参数。设备回收后，实验室将对采集到的样品进行分析，以测定随时间变化的颗粒通量与组分特征。本次部署依托固定式平台完成，所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数字基础设施对外提供；相关数据的质量控制与衍生数据产品均遵循既定规范制作。
