Abstract:

This dataset presents total organic carbon (TOC, wt%) contents in sediments at 19 stations in the Kiel Bight taken during the research cruises BE03/2016 (08.03.2016), BE10/2016 (19.10.2016), BE10/2018 (23.10.2018), BE03/2019 (15.03.2019), L23-13 (13.09.2023 - 15.09.2023), Sagitta24-1 (16.09.2024), Sagitta24-2 (23.09.2024), L25-2b (09.02.2025 - 17.02.2025) and EMB374 (04.09.2025 - 13.09.2025). Sediment cores (<50cm) were recovered using a Multicorer (MUC), Minicorer (MIC) or Rumohrlot (RL). The TOC analysis was performed using an Element Analyzer (Euro EA 3000). The data are used in combination with porewater and water column data to describe the sulfur geochemistry and cycling across different sites in the Kiel Bight and to identify the controlling factors governing the accumulation of hydrogen sulfide at the seafloor.
