Abstract:
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 preserved and analyses were performed onshore (at AWI) shortly after the expedition.

Comment:
The data have been partially published in PANGAEA before (Aromokeye, D A et al., 2018), but with core depth, not sediment depths.
