variableName: d18O
units: permil
description: carbonate
basis: We argue that a substantial and persistent change in !p is required to change the annual mean values of d18Ow in northern Scandinavia.

variableGroup: rainfall source area
scope: climate
scope: climate
basis: All the modern lake and groundwater isotope data lie on the Local Meteoric Water Line (LMWL) (IAEA/WMO, 2006) indicating that evaporation is not important. The similarity of the isotope composition of the lake and its different groundwater reservoirs indicate that the lake is likely to be constantly replenished by groundwater input and subterraneous outflow resulting in a short water residence time.
direction: positive
equilibriumEvidence: our calculated [equilibium] d18OC values of ?12.7? are similar to core values from the last few hundred years, which lends support to the idea that the modern carbonates are precipitating in equilibrium.
