Soil porewater chemistry survey of European peatlands

Porewater and soil samples were collected from 64 natural and rewetted peatlands across Germany (47 sites), Poland (5), Estonia (6), Scotland (3), Sweden (2), and Georgia (1) between 1997 and 2017. A total of 812 anoxic porewater samples were taken from water-saturated soil layers (0–0.6 m depth) using dialysis samplers along 10–20 m transects (Hesslein, 1976). Selected fen sites were monitored for 10–20 years post-rewetting to assess seasonal and long-term nutrient dynamics. The peatlands varied in drainage history and land use intensity, resulting in different degrees of decomposition in the upper peat layers (0–0.4 m depth). The dialysis sampling technique enabled unbiased sampling of oxygen-sensitive dissolved solutes and provided vertical concentration profiles of porewater chemistry (Zak et al., 2004). The data were used to compare porewater composition between rewetted and natural peatlands (bogs and fens), (ii) evaluate the influence of peat characteristics on porewater chemistry in rewetted sites, (iii) examine seasonal variations in nutrient concentrations in rewetted fens, and (iv) assess long-term changes in porewater composition following rewetting.

Continuous water level observations at station BEFmate_I10upp, 2020-01 to 2023-09

Data presented here were collected between 2020-01 and 2023-09 at station BEFmate_I10upp within the research unit DynaCom (Spatial community ecology in highly dynamic landscapes: From island biogeography to metaecosystems, https://uol.de/dynacom/ ) involving the Universities of Oldenburg, Göttingen, and Münster, the iDiv Leipzig and the Nationalpark Niedersächsisches Wattenmeer. Experimental islands and saltmarsh enclosed plots were established in the back-barrier tidal flat and in the saltmarsh zone of the island of Spiekeroog (Germany). Groundwater levels at different elevation zones were measured using pressure loggers deployed in dip wells within the experimental islands as well as in the saltmarsh enclosed plots. Measurements were obtained using Hobo U20L Water Level Loggers (Onset Computer Corporation, Bourne, MA/USA). All devices were pre-calibrated by the manufacturer. Logged data were retrieved in the field using a Hobo Underwater Shuttle (U-DTW-1) and were read out with the HOBOware Pro (V3.7.28) software, Subsequent data processing was done using MATLAB (R2024b). Atmospheric pressure correction for water-level calculations was applied using data from a nearby weather station. Post-processing and quality control included (a) the removal of data covering maintenance activities, (b) an outlier detection, and (c) visual checks. Outliers in water level and temperature time series were detected using a moving-median filter and a 3-sigma criterion, with additional cross-checking against a reference sensor. Identified outliers were removed, and height-corrected water level series were produced to ensure consistency across sensors and years.
