Abstract :
[en] A distinct shift in 18O,13C and trace element contents of the Père Noël (PN) stalagmite from southern Belgium revealed an abrupt climatic anomaly at 8.13±0.03 ka BP (Before Present=before 1950 AD). This anomaly is characterized by a maximum drop in the 18O (-1.4‰ compared the mean) between 8.13 and 8.10 ka BP (±0.03). This drop of 18O coincides with a decrease in 13C and trace element (Sr, Ba and Mg) concentrations suggesting drier conditions. Our precise chronology provides the timing of the outburst of proglacial lakes Agassiz and Ojibway that caused the 18O, 13C and trace elemental anomalies at 8.13 – 8.10 ±0.03 ka BP, which corresponds to the 8.2 ka BP event. The PN stalagmite bears δ18O values in fluid inclusions that covariate with the δ18O values in calcite, suggesting that the speleothem calcite δ18O primarily reflects variations in the rainfall δ18O. Comparison of PN record with different marine and terrestrial archives during the 8.2 ka BP event shows a good agreement in timing and duration suggesting that the PN speleothem can be regarded as a valuable proxy to better understand the 8.2 ka BP event.
