EDoM measurement campaign: CTD data from Pogum

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 subset provides the CTD data collected at the stationary boat location at Pogum (POG).

2018年至2019年间，研究团队开展野外调查，以深入解析埃姆斯河下游与外埃姆斯河口之间的水体与沉积物交换机制。为捕捉因河流径流量变化引发的迥异水文条件，本次研究设置了两次野外测量任务：分别为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）。本次采集的数据集（按单次测量任务统计）包含10个观测点位，各点位至少完成了1个大小潮周期（spring-neap tidal cycle）的观测；其中涵盖2套RWS框架式监测设备（RS）、5个底置式监测装置（BM）以及3套锚链式观测系统（MC），同时开展了8组同步的13小时观测，观测内容包含固定监测站（SB）、跨航道断面（CS）以及1条纵向航道断面的相关数据。本次子数据集包含在波古姆（POG）固定船载点位采集的CTD（温盐深仪）数据。
