Soil temperature, volumetric water content, and electrical conductivity measured every 10 minutes in a grass- and a herb-dominated area at a summer dike, Butjadingen, Germany (Nov 2022–Nov 2023)@en

To understand the role of plant species and functional diversity on the physical soil parameters of a sea dike, especially under prolonged drought conditions, continuous measurements of soil temperature, volumetric water content (soil moisture) and soil electrical conductivity (EC) were carried out from 22 November, 2022, to 22 November, 2023. The measurements were taken using six soil sensors from METER Group's TEROS 12 series, which were installed at three distinct soil depths (4 cm, 14 cm, 24 cm) and on two differently vegetated dike areas: one area with a grass-dominated plant community (referred to as 'Mix-Grass') and one area with a herb-dominated plant community (referred to as 'Mix-Herb'). The sensors were mounted on the southern (inland) side of a summer dike, which is located at the south-eastern North Sea coast of Germany (Butjadingen, Wesermarsch; 'Mix-Grass': 53.61211876 ° N, 8.330925695° E, 'Mix-Herb': 53. 61210826° N, 8.330989015° E), about 1 m below the dike crest. The dike height is approximately 3.6 m above mean high water (MHW). The measurement data was logged at 10-minute intervals using a ZL6 logger from the METER Group.为探究植物物种与功能多样性对海堤物理土壤参数的影响，尤其是在长期干旱条件下的作用，本研究于2022年11月22日至2023年11月22日期间，持续开展土壤温度、体积含水量（土壤湿度）及土壤电导率（Electrical Conductivity，简称EC）的监测工作。本次监测采用METER集团TEROS 12系列土壤传感器共6台，分别布设至3个不同土壤深度（4 cm、14 cm、24 cm），并设置于2个植被类型各异的堤段区域：一处以禾本科植物群落为主（命名为"Mix-Grass"），另一处以草本植物群落为主（命名为"Mix-Herb"）。传感器安装于德国北海南部沿岸布塔丁根（Butjadingen）、韦瑟马尔施（Wesermarsch）区域的某夏季海堤南侧（内陆侧），两处样地的具体坐标分别为："Mix-Grass"样地：53.61211876° N，8.330925695° E；"Mix-Herb"样地：53.61210826° N，8.330989015° E，传感器布设位置距堤顶下方约1 m处。该海堤高度较平均高潮位（Mean High Water，简称MHW）高出约3.6 m。监测数据通过METER集团ZL6数据采集器以10分钟的间隔进行存储记录。
