EDoM measurement campaign: data from RWS frames

In 2018 and 2019 field surveys were conducted to better understand water and sediment exchamge mechanisms between the lower Ems River and the outer Ems estuary. In order to capture the contrasting conditions resulting from river discharge variability, two measurement campaigns were defined: one in August 2018 (local summer with relatively low river discharge) and one in January 2019 (beginning of the wet winter conditions). The collected dataset comprises (per campaign) of 10 observation locations measuring for at least one spring-neap tidal cycle (2 RWS frames RS, 5 bottom mounts BM, and 3 mooring chains MC) 8 simultaneous 13-hrs observations (including fixed stations SB, cross-channel transects CS, and one longitudinal transect). More detailed description of the data is provided in the accompanying report (report-EDoM-v2.0.pdf).

2018年至2019年，为深入解析埃姆斯河下游与埃姆斯河口外区域间的水沙交换机制，研究团队开展了野外实地调查。为捕捉河流径流量波动带来的迥异水文条件，本次研究设置了两组测量作业：分别于2018年8月（当地夏季，河流径流量相对偏低）与2019年1月（湿润冬季初期）实施。本次采集的数据集按每组测量作业统计，包含10个观测点位，所有点位均至少完成1个大小潮周期（spring-neap tidal cycle）的观测；其中点位类型涵盖2套RWS框架（RS）、5个底置式安装单元（BM）与3套锚链式锚泊装置（MC）。此外，同步开展了8组时长13小时的观测工作，观测范围覆盖固定监测站（SB）、跨航道断面（CS）以及1条纵向航道断面。该数据集的详细说明详见随附报告report-EDoM-v2.0.pdf。
