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

Description: 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).
