Figure 3. Chronology of the PD in the Central Spain paleoglaciers and paleoclimate setting.

(a) Probability distribution functions of the ¹⁰Be ages for the two stages. Black vertical lines represent the stage ages with the grey vertical bars being the standard error of the mean. (b) ISI variability for 40°N¹⁸ for most likely τ configurations; τ = 325 (dashed); 350 (solid) and 375 (dotted). (c) Eagle Cave δ¹⁸O record (light blue) and ice volume corrected δ¹⁸O record (dark blue) with a 0.2 ka filter (bold blue). The isotope ratio correction takes into account sea level changes by Peltier and Fairbanks³⁷ considering a rate of change of 0.06‰/10 m of sea level³⁸. (d) Black rectangles labelled H1 to H3 refer to Heinrich events³⁹. (e) Green rectangle corresponds with the period of lack of calcite deposition in Villars Cave (southern France) due to extreme cold conditions²¹. Error bars indicate U-Th ages uncertainty.
