Main Endeavour Field Sediment Trap Deployed 2015-09-10

The McLane Parflux MK78H-21 Sediment Trap (SN 12294-02) was deployed on 2015-09-10 at Main Endeavour Field. Main Endeavour Field is a vent field located at Endeavour Ridge, where hydrothermal vent systems 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（Sediment Trap，序列号SN 12294-02）于2015年9月10日部署于主恩多弗尔喷口区（Main Endeavour Field）。主恩多弗尔喷口区是坐落于恩多弗尔海岭（Endeavour Ridge）的热液喷口区域，区内已观测到热液喷口系统（hydrothermal vent systems）。该设备为沉积物捕集器，通过锥形捕集结构将沉降颗粒物引导至多组样品瓶中；随着仪器旋转，可依次采集各采样瓶内的试样。沉积物捕集器支持用户远程触发采样，或按照预设计划自动启动采样，并可记录每次采样事件的运行参数，包括采样日期、时间及采样时的环境温度。仪器回收后，实验室将对采集的样品进行分析，以获取随时间变化的颗粒物通量（particle flux）及其组成成分。本次部署采用固定式平台搭载该设备。本部署产生的相关数据已通过加拿大海洋网络（Ocean Networks Canada）的Oceans 2.0数字基础设施完成归档并对外公开，相关数据的质量保障（quality assurance）及衍生数据产品均遵循既定行业规范。
