Dataset: Coastal wetland soil redox potential, tidal water level, and salinity and terrestrial groundwater level, 2022-2023, Maryland

This dataset consists of two years (2022-2023) of coastal wetland automated soil redox measurements and accompanying tidal data, including water level and salinity, as well as terrestrial groundwater level data. Coastal wetland data were collected from the ambient control plots in SMARTX, a long-term experiment in Smithsonian’s Global Change Research Wetland (GCReW), part of Kirkpatrick Marsh in Edgewater, MD. Redox data was collected using platinum-ringed probes at 5 and 20 cm below the soil surface every 30 min from 2022 to 2023 and marsh water level data was collected every 15 min using an AquaTROLL 200. Terrestrial groundwater level data were collected from the adjacent Terrestrial Ecosystem Manipulation to Probe the Effects of Storm Treatments (TEMPEST) experiment (Hopple et al., 2023). Groundwater level was measured using an AquaTROLL 600 multiparameter sonde deployed in groundwater wells in the center of the control plot, which does not receive flood manipulation treatments.

本数据集涵盖2022—2023年两年的滨海湿地自动化土壤氧化还原（redox）测量数据，以及配套潮汐数据（含水位与盐度）与陆地地下水水位数据。滨海湿地相关数据采集自史密森尼学会全球变化研究湿地（GCReW）长期实验站点SMARTX的环境对照样地，该站点位于美国马里兰州埃奇沃特的柯克帕特里克沼泽范围内。2022至2023年间，研究人员采用铂环探针，于土壤表层下5 cm与20 cm处每30分钟采集一次氧化还原数据；使用AquaTROLL 200型设备每15分钟采集一次沼泽水位数据。陆地地下水水位数据采集自相邻的“风暴处理效应探测陆地生态系统操控实验（TEMPEST）”项目（Hopple等，2023）。地下水水位通过部署于该对照样地中心地下井内的AquaTROLL 600型多参数水质仪进行测量，该样地未接受洪水操控处理。
