Geochemistry of karst headwaters

This study investigated CO2 degassing and related carbon isotope fractionation effects in the Wiesent River that drains a catchment in the karst terrain of the Fraconian Alb, Southern Germany. The river was investigated by physico-chemical and stable isotope analyses of water and dissolved inorganic carbon during all seasons in 2010 along 65 km long downstream transects between source and mouth. This data set contains the results of field and solute parameters (temperature, conductivity, pH, total alkalinity, total CO2, and pCO2) and stable isotope analyses (d2H-H2O, d18O-H2O, d13C-DIC) for the Wiesent River and major tributaries.
