Spatial suitability distribution for Ostrea edulis habitats within German Bight marine protected areas

The presented data shows the results of suitability analyses to assess potential restoration grounds for ostrea edulis in the German Bight's marine protected areas (MPA) Borkum Reef Ground and Sylt Outer Reef. We made use of existing marine data from various sources and applied a spatial multicriteria decision analysis (MCDA). Spatial input variables are scored uniformly in order to express their respective ability to improve restoration preconditions. They are summed in a linear combination using expert's judgements founded weights using the analytical hierarchy process (AHP) algorithm. Datasets which describe circumstances to prevent a successful restoration are subtracted from the resulting suitable area. The dataset presented here includes the resulting raster datasets as described in out publication. Detailed metadata on the original raw data (not included here) are listed in Table 1 of the publication. The Analysis was performed in 2021 and modified in 2022.

Biogeochemistry and qPCR data for microbial community adaptation to brackish water rewetting in a coastal peatland

Coastal wetlands can serve as natural laboratories for assessing the future impacts of sea-level rise and the intricacies of the effect of sulfate (SO42-) on emissions of greenhouse gases, such as methane (CH4) and carbon dioxide. In the case of previously drained and freshened wetlands, we can observe how freshwater terrestrial microbial communities react and adapt to intrusion of SO42- rich saline waters. We conducted a 3-month anoxic incubation experiment with soil extracted from a peatland on the German Baltic coast which was rewetted with brackish water in late 2019 to examine how microbial communities at the site had adapted to the new conditions after two years. Soil slurries were incubated at a moderate temperature of 15 °C at two different salinities (reflecting surface water and average peat soil water salinity) and sampled at 8 timepoints. At each timepoint 5 replicates of each treatment were destructively harvested and sampled for concentrations of CH4, dissolved inorganic carbon (DIC), total aqueous organic carbon, SO42-, ammonium, and other major ions, pH values, qPCR analysis, and δ13DIC and δ13CH4 values.
