description: carbonate
basis: Spannagel ?18O records and growth phases are in agreement with the ?18O pattern in Greenland ice cores on millennial to orbital timescales (Spi¿½tl and Mangini, 2007 Spi¿½tl et al., 2006), with sediment proxies and growth of deep-sea corals from the North Atlantic (Frank et al., 2009; Mangini et al., 2005) and with other stalagmites from central Europe (Mangini et al., 2007). Trouet et al. (2009) found and discussed similarities of Spannagel speleothem ?18O values in relation to their NAO reconstruction for the past 1000 yr based on speleothem data from Scotland (Proctor et al., 2000) and tree-ring data from Morocco (Esper et al., 2007). In addition, the super-regional character of our alpine location was explicitly demonstrated in a proxy intercomparison study investigating teleconnections between the tropical Pacific and mid-latitude regions (Graham et al., 2007).

basis: The observed strong decrease in the ?18O by about 1.5? between 11 and 10 ka, for example, is rather a change of the source region than a pure temperature effect. Based on this assumption, during the deglaciation the trajectories more frequently followed southerly routes. Towards the transition into the Holocene the main contribution of precipitation probably originated from more northern regions of the Atlantic, where the surface ocean is generally more depleted in 18O (LeGrande and Schmidt, 2006).
coefficient: NA
direction: positive
equilibriumEvidence: Owing to the low cave temperature kinetic isotope effects are minimal (Mangini et al., 2005; Vollweiler et al., 2006).
fraction: NA
inferredMaterial: groundwater d18O
integrationTime: Average resolution of each stal 5.1 yr (SPA12), 3.5 yr (SPA128), 8 yr (SPA70), 4 yr (SPA127) and 1.6 yr (SPA133).
integrationTimeBasis: iscam method (Fohlmeister et al., 2012), based on simulations and correlation calculations between pairs of climate records (this is a stack of 5 records). Point-wise linear interpolation between data points. Typical age errors are smaller than 2%.
