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...

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...

Pore water for iron isotope analysis was collected by use of rhizons, acidified and stored at 4°C until processing onshore. Processing of pore water (purification and matching)...

Pore water was collected onboard (RV Heincke expedition HE443) by use of rhizons that were inserted into the cores through drilled holes in the core liners. Samples were...

This is a compilation of pore-water and solid-phase data for station HE443/10 in the Helgoland mud area (German Bight, North Sea). The data derive from a multicorer core...

Surface sediment were extracted 4 times by ultrasonication with dichloromethane: methanol (9:1, v/v) for 15 min for FAs and alkanes. For quantification of FAs and alkanes, known...

The grain size of sediments was determined with a Cilas 1180 laser-diffraction particle analyzer (range 0.04–2500 μm) and the mean grain size was calculated. The surface area...

In March 2022, 56 surface sediments were collected from the Helgoland Mud Area and surrounding sandy areas in the North Sea. These surface sediments were analyzed for grain...
