EDoM measurement campaign: along-channel data

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). This dataset provides the along-channel data. More detailed description of the data is provided in the accompanying report (report-EDoM-v2.0.pdf).

2018至2019年，为深入解析埃姆斯河下游与外埃姆斯河口之间的水沙交换机制，研究团队开展了野外调查。为捕捉河流径流变化引发的差异化水文条件，研究设置了两组测量航次：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）开展。本次收集的数据集按航次划分，每组航次包含10个观测点位，各点位至少完成1个大小潮周期（spring-neap tidal cycle）的连续观测，其中点位类型涵盖2个RWS框架（RS）、5个底置式观测装置（BM）与3个锚链式观测装置（MC）；同时开展8组同步的13小时连续观测，观测覆盖固定站（SB）、跨河道断面（CS）与1条纵向河道断面。本数据集提供沿程河道观测数据，详细说明详见随附报告（report-EDoM-v2.0.pdf）。
