Pore-water DIC and δ13C-DIC data, as well as solid-phase porosity and TOC data from a MUC core from RV HEINCKE cruise HE595 at Tonne E3 in the Helgoland Mud Area, SE German Bight

Description: This dataset includes downcore measurements of dissolved inorganic carbon (DIC) and its stable carbon isotopic composition (δ13C-DIC), as well as solid-phase porosities and total organic carbon (TOC) contents from a sediment core retrieved using multi-corer sampling during RV Heincke expedition HE595 in 2022. The samples were collected in the framework of the Project APOC (Anthropogenic impacts on particulate organic carbon cycling in the North Sea). DIC contents were determined in the laboratories of the Alfred Wegener Institute (AWI) in Bremerhaven, Germany. The δ13C-DIC data were produced at MARUM—Center for Marine Environmental Sciences, University of Bremen, Bremen, Germany. Solid-phase porosity data were produced in the laboratories of the Alfred Wegener Institute (AWI) in Bremerhaven, Germany. Total organic carbon contents were determined at the Faculty of Geosciences at the University of Bremen, Bremen, Germany.
