EDoM measurement campaign: data from Mooring Chains

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至2019年，为深入探究埃姆斯河下游与外埃姆斯河口之间的水沙交换机制，研究人员开展了野外实地调查。为捕捉河流径流量变化带来的迥异水文条件，本次研究设置了两组观测场次：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观测场次划分，包含10个观测点位，各点位均完成至少1个大小潮周期（spring-neap tidal cycle）的观测，其中涵盖2个RWS框架式测点（RS）、5个底置式观测装置（BM）及3个锚链式观测锚系（MC）；同时包含8组同步进行的13小时观测，观测内容覆盖固定观测站（SB）、跨航道断面观测（CS）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》。
