Isotope and water chemistry - 30 Polish lakes

The dataset presents the results of a seasonal monitoring (in 2012) of water chemistry and carbonate precipitation in 30 hardwater Polish lakes located along the temperature gradient (west-east). We collected the information about water chemistry (surface water temperature, pH, conductivity, Ca2+ and HCO3-) and we measured the dD, d18O from water samples, and d13C and d18O from carbonates deposited in sediment traps.
The overall monitoring program was designed to capture a pattern of relationships between meteorological conditions and carbonate precipitation.
