Bottom Water (collected with the benthic trace profiler (BTP)) geochemical and Ni isotope data collected during ALKOR cruise AL543

The reactivity and isotope fractionation of Ni is strongly influenced by biological and redox-related processes in the ocean, giving the isotope system (expressed as δ60 Ni) some potential for studying past ocean environments. This requires, however, a profound understanding of its modern elemental and isotopic oceanic mass balance. In order to better understand mechanisms determining fluxes of Ni and its isotopes from the sediment-porewater system in reducing ocean settings, we present trace metal concentrations and Ni isotope data from sediments, porewaters and the water column of the shallow-water Kiel Bight, in the southwestern Baltic Sea. The samples were collected during RV Alkor cruise AL543. Trace metal concentrations in porewater, bottom water and BTP bottom water samples were measured on a Thermo Scientific Element XR and Nickel isotope compositions were measured using a Thermo Scientific Neptune Plus MC-ICP-MS. Digestion solutions of sediments and suspended particulate matter were measured by ICP-OES.

Stable isotope (2H and 18O) depth profiles of pore waters and inferred soil physical parameters in the Attert catchment, Luxembourg

Radiographs of the gravity core HE443/10-3 from North Sea

Radiographs of gravity core HE443/10-3 that was collected in the Helgoland mud area. The radiographs were produced about 8 months after coring and sampling. The white spots derive from previous sediment sampling that was performed onboard through windows that were cut into the core liner. The core shows intervals with intact sedimentary structures, but also intervals that are strongly mixed by bioturbation.

Solid phase iron isotopic composition of a gravity core at Station HE443/10, North Sea

Solid-phase samples were collected onboard (RV Heincke expedition HE443) using cut-off syringes. The MUC was sliced and sampled. For sampling the GC, small windows were drilled into the liner through which the syringes were introduced. All samples were stored anoxically and frozen at -20°C until processing. The processing involved freeze-drying and grinding. Extracts deriving from the sequential extraction of Fe phases were processed for stable Fe isotope analysis after Henkel et al. (2016).

Solid phase geochemistry of a multicorer core and a gravity core at Station HE443/10, North Sea

Solid-phase samples were collected onboard (RV Heincke expedition HE443) using cut-off syringes. The MUC was sliced and sampled. For sampling the GC, small windows were drilled into the liner through which the syringes were introduced. All samples were stored anoxically and frozen at -20°C until processing. The processing involved freeze-drying and grinding before splitting the samples for the different kinds of analyses.
