Fig. 3 (a–j) Selected water profiles demonstrating chemical stratification of LGM for two sampling dates in summer 1994. Data for surface water and deep-water composition of LPM are given inside the diagrams for comparison. Sulphate increase and Fe decrease between 22 August and 18 September 1994 document subsurface inflow of oxygen-bearing groundwater into LGM, slight Na and Cl increase in the surface water of LGM documents concentration increase due to evaporation. Increase of the Dissolved Salt Content (DSC) in the deep water is mainly contributed by DIC, Ca and NH4. There are no indications for incomplete seasonal mixing of the LGM water body
