Environmental properties determined for sediments, pore water (indicated by #) and lake water (indicated by *) sampled in October 2013 from nine saline-alkaline lakes in the national park “Neusiedler See-Seewinkel”, Burgenland, Austria.

Values marked with § denote data derived from the literature [32]. Missing data marked with NA (not available) was due to insufficient material for determination. Salinity values were estimated using a regionally constant correction factor [31]. Per cent units for carbonate and Ntot refer to the percentage weight of dried sediment.
