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.
