Abstract:

This dataset collection presents measurements of microbial sulfate reduction rates (SRR), mircrosensor profiles, and benthic chamber experiments from eight stations, in Kiel Bight, near Fehmarn and Flensburg Fjord from 2023 to 2025. Sediment cores were recovered using multicorer (MUC), minicorer (MIC) or Rumohr lot (RL), with multiple core liners (MUC/MIC) used per deployment for microbial, geochemical, and sensor analysis. The dataset provides the first spatial and temporal overview of sulfide production in sediment and water column of Kiel Bight, small-scale putatively microbial influenced vertical gradients of the upper sediment, and flux rates between sediment and bottom water. Further geochemical data from the same deployments can be found in Spiegel et al. 2026 https://doi.pangaea.de/10.1594/PANGAEA.988013. Together these datasets enable assessments of microbial-geochemical controls on sulfide production, retention, and emission to the bottom water of Kiel Bight under changing regimes.
