Three different labs and instruments: (1) Finnegan MAT 252 isotope ratio mass spectrometer equipped with a Kiel carbonate device; (2) Finnegan Delta E gas source ratio mass spectrometer; (3) GasBench-IRMS system

more positive values of d18O are interpreted to reflect less rainfall throughout the "amount effect" and the fact that during dry years, the water in the soil (due to evapotranspiration) has more positive d18O values. More positive d13C indicates decreased biological activity in the overlying soil during drier conditions

negative (more rainfall, more negative d18O and d13C)

both d18O and d13C are recording changes between wetter and drier conditions in the external environment, with more soil activity during wet years

An online, automated carbonate preparation system linked to a triple collector gas source mass spectrometer at the University of Innsbruck

equilibrium is evidenced by the lack of correlation among d18O and d13C

TP: added site elevation; TP (30/12/19): In fact, the age information is not missing, but the depth and age columns in the dataset were mislabelled (age column was labelled 'depth', and depth column was labelled 'age'). LCB: Missing age/year. See plot. ZK (14/01/2019) the time span should be 1635 - 1995 AD; BM (14/03/2019) info sent using GitHub
