Extended Data Fig. 3: Cation concentrations normalized against chlorinity.
From: Deglaciation drove seawater infiltration and slowed submarine groundwater discharge

Porewater cation concentrations of Boron (a), Barium (b), Calcium (c), Potassium (d), Lithium (e), Magnesium (f), Manganese (g), Sodium (h) and Silicon (i). The reported cation concentrations have the following uncertainties: calcium (Ca) ≤ 3%, potassium (K) ≤ 4%, magnesium (Mg) ≤ 4%, sodium (Na) ≤ 1%, sulfur (S) ≤ 4%, boron (B) ≤ 2%, barium (Ba) ≤ 3%, lithium (Li) ≤ 1%, manganese (Mn) ≤ 5% and silicon (Si) ≤ 3%.
