18O-enrichment in Marcella Lake water caused by summer effective moisture conditions; These prominent late Holocene changes in effective moisture occurred simultaneously with changes in Aleutian Low circulation patterns over the Gulf of Alaska indicated by Jellybean Lake. The reconstructed climate patterns are consistent with the topographically controlled climatic heterogeneity observed in the coastal mountains and interior valleys of the region today

effective moisture occurred simultaneously with changes in Aleutian Low circulation

Temperature fractionations between calcite and lake water were considered and are thought to be minor (0.25%/1C).

dsample 1?4 ([Rsample/Rstandard]-) x 1000 where R = 2H/1H, 18O/16O in sample and standard, respectively; First, the oxygen isotope stratigraphy from each lake was converted into three smoothed time-series at 50, 100 and 200-year intervals to examine multi-decadal and longer-term variations (Figs. 5a and b). Second, the Jellybean-d18OCa time-series were subtracted from the Marcella-d18O Chara time-series to produce a third, Dd (Fig. 5c). Variability of evaporation-insensitive Jellybean-d18OCa is relatively small (1.5?2%) compared to Marcella Lake (4.0?5.0%), but there are intervals where the d18Op correction results in  distinguishable effects on long-term trends of Marcella-d18OChara (note arrows in Fig. 5a and c). The smoothing procedure was done to eliminate problems due to temporal mismatches between individual samples from the two cores but given the nature of the trends does not significantly effect the uncertainty regarding timing of prominent shifts or long-term trends.
