Corrigendum to “Evidence for solar influence in a Holocene speleothem record (Père Nöel cave, SE Belgium)” (Quaternary Science Reviews (2018) 192 (249–262), (S0277379118302038) (10.1016/j.quascirev.2018.05.039))

When this paper was originally published, there was an error in Fig. 7g. Indeed the curve of percentage of hematite-stained grains measured on North Atlantic MC52-VM29-191 core, published by Bond et al. (2001), was inverted. Please find the correct Fig. 7 below: [Figure presented] Fig. 7 corrected: (a), (b) and (c) PN trace elements contents (Sr = red line; Ba = green line; and Mg = black line) in comparison to (d) PN Stalagmite δ 18 O (blue line), (e) δ 18 O record from Bunker Cave-W Germany (Fohlmeister et al., 2012), (f) δ 18 O record from lake Ammersee- Germany (von Grafenstein et al., 1999), (g) hematite-stained grains from the North Atlantic (Bond et al., 2001), (h) frequency of wet/dry events in the Northern Hemisphere as defined by Wanner et al. (2014). The blue horizontal bars mark cold events. In the paper, Fig. 7 allows us to compare the trace elements Ba, Sr, Mg and δ 18 O isotopes results of Père Noël (PN) stalagmite with other continental and marine records. In the figure, the blue lines underline the 6 geochemical events measured in our speleothem PN record that we attribute to cold events. As a first point, we note that most of the PN events are consistent with some of the dry events (Fig. 7h) defined by Wanner et al. (2014) for the Northern Hemisphere. The correspondence is clear for 5 intervals corresponding to the 2.6–2.8, 4.6–4.8, 6.2–6.4, 8.1–8.3 and 9.3–9.5 Wanner events (no data for the oldest event at 10.3–10.7). Second, we compare the PN record with the abundance of hematite-stained grains in core VM29-191 (Bond et al., 2001). This curve, that was used as one of the drift ice indices, represents the North Atlantic cold events. (Note the comparison with the stacked curve would lead to the same conclusion). At least the 3 PN events at 4.6–4.8, 6.2–6.4 and 9.3–9.5 ka BP occur in a time interval consistent with the Bond events 3, 4 and 6, respectively. In the manuscript, the text must be corrected (see lines 416–418):“During these three intervals (i.e., around 10.5, between 9.5 and 9.2 and between 8.4 and 8.2 ka BP), the wavelet spectrum of trace elements shows that the solar imprint is well present in the PN stalagmite (Fig. 6). Those three intervals may correspond to Bond cycles (Bond et al., 2001)”. Indeed only the 8.4-8.2 ka BP and 9.3–9.5 event may be related to Bond cycle since the 10.5 event is not covered by the Bond curve. There is no peak-to-peak correspondence between the two curves than are characterized by different age uncertainties. PN record presents an age uncertainty estimated at ±11–51 years at 2σ level for the interval 2–9.5 ka BP (see Table 1 in our manuscript). The chronology of the Bond et al. records presents an age error estimated at 50 years (1σ). Whatever the 8 Bond events display, as stated in the Fig. 2 caption of Bond et al. (2001), “a millennial-scale cycles regarded as part of the North Atlantic's 1500-year cycle”. Such millenial cyclicity was revealed in our PN trace element record by a 912–1029 yr peak in the wavelet spectral power (Fig. 6). Such periodicity may suggest some solar forcing in our PN record.
