For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.927610"! ** Pore water was extracted from the core with 5 cm CSS Rhizon samplers (Rhizosphere, Wageningen, Netherlands). Saturation index is given as log₁₀(IAP/Ksp) with IAP = Ion activity product and Ksp = Equilibrium constant.
