EDoM measurement campaign: cross-channel transect 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 cross-channel data. More detailed description of the data is provided in the accompanying report (report-EDoM-v2.0.pdf).

2018至2019年，为深入厘清埃姆斯河下游与埃姆斯河口外域之间的水沙交换机制，研究团队开展了野外调查工作。为捕捉河流径流量波动所引发的迥异水文条件，本次研究设计了两组测量作业，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。按每组测量作业统计，本次采集的数据集包含两类观测内容：其一为10个观测点位，所有点位均完成至少1个大小潮周期的观测，其中包括2个RWS框架站（RWS frames RS）、5个底置式监测站（bottom mounts BM）与3个锚链式监测站（mooring chains MC）；其二为8组同步开展的13小时观测，观测覆盖固定监测站（fixed stations SB）、跨航道断面（cross-channel transects CS）与1条纵向航道断面。本数据集提供跨航道相关观测数据，更详细的数据说明可参见随附报告（report-EDoM-v2.0.pdf）。
